Transmission Gear Slipping Problems of Nissan Frontier - part 1

I bought the 2007 Nissan Frontier off a dealership as a used vehicle with no warranty. One week later the transmission started to slip, the following week the slippage was worse until it lost power and it left me stranded in a parking lot. I took it to my mechanic and he said that it's a possibility that the transmission computer had gone out and it would be close to $5,000 dollars to replace the transmission. The transmission fuse keeps blowing out once the truck is started. The mechanic said it could be a possibility that it was cross contamination since Nissan was known for faulty radiators. So I'm stuck with a truck payment through a loan with a transmission out and I can't even drive it. There are thousands and thousands of complaints online from people having the exact same issue.

Transmission started slipping and then lost reverse. And finally just kept slipping and wouldn't move more than a few hundred feet ,and would turn off and wouldn't restart until the transmission cooled off,and when it restarted the idle or tachometer would jump into the red line area even though the truck wouldn't drive past 20 mph. Coasting on the freeway I would pull to the side and have cars drive around mr while trying to push it off the shoulder,looking for an off ramp to go to the nearest transmission shop I could find. . Secondly I had to replace my fuel sender and or. My fuel pump I t went out when I was driving down the freeway thinking I had a half a tank when actually it was on empty . . So I really never knew how much fuel it had until I got it fixed at sam's automotive in beaumont CA . 92223 and sam has returned and sold the business so I have no receipt only remembering it costs between 500 and 100 dollars . . And yes I checked and it too had a recall and I was never notified.

Transmission started slipping and then lost reverse and finally just kept spinning and wouldn't move more than a few hundred feet and would turn off and not restart till transmission cooled off . . And when it would restart the idle or tachometer would accelerate into the red line area while coasting on the freeway heading to nearest transmission shop I could find off freeway.

Apparently coolant mixed into my transmission and it is now slipping. And repair will cost $4500. 00 or more. I heard a slight clunk when driving then it started to slip.

When truck gets warm first gear start slipping and hard to get the truck to move fluid levels are where they should be the vehicle was in motion at a drive-thru tobacco shop.

Drivers airbag light is on. Also transmission slipping anti-freeze mixing with transmission fluid.

Radiator leaks into transmission causing failure. The transmission slipped into neutral entering 45 mph traffic on a 4 lane city street leaving me stranded and blocking traffic. It is currently in the shop and will cost 3000. 00.

Driving on a trip transmission started slipping and jerking. Had to drive slow in third gear with it still slipping. Radiator fluid was foamy. Truck still in driveway. Four to five hour trip on highway with some hills didn't think I would make it home. A few years back we received a service notice of failed radiator. Took truck to nisan and they would not replace unless there was a problem.

The contact owns a 2005 Nissan Frontier. The contact stated that the transmission slipped and the vehicle experienced abnormal vibration. Upon inspection, the contact noticed that the transmission fluid mixed with the radiator fluid. The vehicle was taken to the dealer where it was confirmed that the transmission fluid mixed with the radiator fluid and stated that the transmission needed to be replaced. The manufacturer was notified of the failure. The failure occurred without warning. The failure mileage was 81,000.

When entering hwy 17 (70 mph speed limit) I pressed the gas pedal to the floor to enter oncoming traffic. Instead of increasing speed the truck stalled. I pulled onto the right side emergency lane in order to prevent traffic from running over my vehicle. I placed the transmission in park and it seemed to smooth out . Motor was running with excess rpm's and transmission was slipping. This was a near accident. I could hear cars behind placing on brakes and blowing horn. When returning home was told by Nissan dealership radiator cooler and transmission had to be replaced due to faulty lines. Nissan should have recalled this problem.

My radiator had failed causing transmission fluid to enter the coolant and coolant to enter the transmission. Once Nissan replaced the radiator and flushed out both systems, the transmission seem to drive ok, and the Nissan dealer said it seems to be ok. After driving the vehicle for a month the transmission has developed slippage due to the previous radiator with an internal transmission cooler that caused internal damage to the transmission. If Nissan had built the truck with an external transmission cooler separate from the radiator, I wouldn't have had an issue with the transmission once the radiator failed. As an ase certified mechanic with working in the industry for 10 years, also serving in the military as a maintenance mechanic, and with all the different models of vehicles that I have owned; have I ever had this problem where one component fails that would cause me to replace a transmission. I am starting to believe that Nissan is not any better than owning any other car, as the technology seems to not be getting better but more costly to us the consumers. The vehicle was drivin at about 30 mph when the truck temp gauge elevated, and coolant burping out. I immediately shut it down to check and discover the issue was the radiator. Once taken to the shop by tow truck the shop said the transmission fluid had coolant inside and transmission fluid inside the engine coolant area and passages.

Transmission slips and the first gear so rough.

Transmission starts slipping at highway speed. Rpm increases without increase in speed. Intermittent but getting worse. This is my son's truck and I am worried about his safety when merging into the interstate. He almost got hit by a semi last week when merging into I-20 as the slipping was happening.

My transmission began slipping slightly and when the fluid was checked, we noticed that there was radiator fluid getting sucked into the transmission. Shortly after that was noticed, the transmission completely stopped shifting and left me stranded on the side of the road. It has 100,000+ miles on it so the warranty will do nothing for me and neither will the class action lawsuit that I've found some information on therefore, it has been sitting in my driveway for over a year because I cannot afford to have it fixed at this point.

At 32000 on the freeway hadn't shifted in miles clutch begins to smoke, transmission slips power loss, with five miles lost any gear in transmission forward or reverse and no clutch. If it wasn't night and I was in heavy traffic would not have been good. Unknown for sure either weak defective clutch throw out bearing or bad hydraulic clutch system. 5t.

My 2007 Nissan Frontier heater would not warm up when idling. I took it to the dealership in December 2014 and they flushed the lines. Six months later the transmission began to slip. I took it back to the dealer and they informed me that due to a manufacturer's defect engine coolant leaked into the transmission and destroyed it! I would need a new transmission and radiator. Because the vehicle was now 8 years old, the warranty will only cover part of the cost and I am responsible for $2,500. After researching this problem, I found that one of the warning signs was a heater that would not warm up while idling. The vehicle could have been fixed in December of 2014 and covered fully by warranty, however, the dealer did not warn me! now, Nissan says there is nothing they can do! I'm frustrated to say the least and have purchased my last Nissan!.

Transmission was slipping bad, and the coolant was looking brownish red. Transmission fluid was in the radiator and through out both the engine and transmission. When I took it to the dealership to get check-out they said my warranty had expired and that this wouldn't be covered. Would need to replace radiator and transmission. . . . Costing me $ 2,731. 25. Although this is a known fact that Nissan is having a good amount of problems with various Nissan model including my Nissan Frontier. Very unhappy Nissan customer of many years. . . . . Now I'm starting to have timing belt issues which falls under another Nissan Frontier problem. Will have to get fixed at my own expense. My dealership know these things but are not open about these fact. I take my Frontier in for maintenance nothing ever said and never seem to get recall notices either. . . .

Nissan has acknowledged that a manufacturer defect in 2005-10 Frontier, pathfinder, and xterra vehicles equipped with automatic transmissions have an internal crack on the oil cooler tube may occur leading to internal leakage of engine coolant. This defect has destroyed my transmission and many other consumers' transmissions, as evidenced by the class action lawsuits which have been filed against Nissan. Nissan offered customers an extended warranty for the radiators for vehicles with less than 100,000 miles, but never addressed the transmission issues, which range from $4000-6000 to rebuild. I realized I had an issue with the transmission while making a left turn on hwy 98 in florida, where oncoming traffic is traveling at speeds of greater than 60 miles an hour. The transmission slipped while I was making the turn and was nearly t-boned by two oncoming vehicles. It is inconceivable that Nissan has not recalled these vehicles. Nissan is putting consumers lives in danger and costing hard-working americans substantial amounts of money by not recalling these vehicles.

I own a 2005 Nissan Frontier. At about 84365 miles, the transmission started slipping badly. The mechanic said that my transmission cooler had ruptured inside the radiator and coolant had gotten inside the transmission. My transmission was basically destroyed and it cost over $5000. 00 to fix it. After reading other articles about Nissan owners with similar experiences, I think this is outrageous and Nissan should be held accountable for these failures.

While getting on the freeway, I accelerated to merge with traffic but was unable to gain speed so I got off on the first exit ramp. Had plenty of engine power but lost torque. First thought, must be the transmission slipping. Got home and checked the transmission oil level and it was fine, the oil did not look like transmission oil, it was discolored and had a different feel to it. Was able to get the truck to dealer and was told it needed a radiator and transmission. Coolant had leaked into the transmission. Did my research and found there have been many complaints about this problem. As for the warranty,by which I still have to pay over $2500, I believe Nissan should have had a recall on the 05 Frontier, pathfinder, and payed for the whole repair for their use of what I call defective parts. ( radiator & transmission cooler ).

I went to drive the truck and started to notice the transmission slipping. I called Nissan and the service department said there was not a recall for my truck. I have since found out the transmission is no longer usable and that many other people are noticing the same problems.

I was driving along on a major interstate at 65 mph when my engine was revving up to about 3500 or 4000 rpm but my speed was dropping. I pulled over to the right hand side of the road, stopped and turned the vehicle off. Had I not been in the right lane of the major interstate when traffic was very light, I could have had a major accident. Everything seemed normal except the low coolant level in the reservoir bottle. There did not appear to be any problems with the engine so then I placed the truck into drive and moved the vehicle forward. As the vehicle picked up speed and at about the 35 to 40 mph the truck engine would rev up but the transmission was slipping and not allowing the truck to move any faster. When I took the screw off the transmission dipstick to see that that fluid level was too high for the proper level in the automatic transmission. Also, I noticed that the fluid had a greyish milky appearance which is a clear indication of contamination with a water based material such as engine coolant. I find the fact Nissan clearly knew that was a problem and failed to notify me as the original owner of the vehicle annoying. They would rather pay to have vehicle repaired after the fact than take care of a potential safety problem before it occurs. This is extremely troublesome when a manufacturer places profits and the bottom line ahead of customer safety. Upon further research, I have learned that I could have replaced the faulty radiator with another product from koyorad for about $120 retail and prevented this problem. So for a couple hundred dollars, Nissan is willing to jeopardize my safety and all other Nissan owners safety. As the national safety agency, I implore you act immediately and order a recall on these Nissan vehicles before people get hurt. It is your duty to protect the people of the nation from safety issues when manufacturers fail to do so.

Transmission slipped and loss power while driving down the highway. Dealership service department claims issue is a common complaint with this vehicle. Actually has an extended warranty because of it.

Apparently a known issue with the radiator leaking into the transmission - causing an $3000 repair to a vehicle that was well-maintained. The transmission started slipping and after diagnostics was told by the mechanic this was an issue that Nissan knew about and never did anything about. Spent $3000 of my money to fix something that should have been prevented and fixed by the manufacturer. I liked Nissan, but after this; I may not buy anymore. Have documentation to prove the issue.

Over the course of approx 2 weeks the vehicle experienced transmission slippage and engine overheating. Then the transmission ceased to function. The vehicle had to be towed to a transmission shop. The transmission failed due to radiator coolant leakage into the transmission. The vehicle needed a completely rebuilt automatic transmission, and radiator. Total repair fees were $3495. 00 including towing. Was told by transmission shop that this was a very common problem for Nissan radiators. Called Nissan local dealership, they quoted a price of over $5500. 00 just for the transmission. Radiator and towing would be extra. I was informed that Nissan refused to offer warranty or other compensation.

The Nissan Frontier radiator contaminated the transmission with coolant thus causing the transmission to malfunction in a busy traffic area. This issue caused my vehicle to shutter thus forcing the traffic to the rear of me to lock up brakes to avoid hitting me. To my dismay, this problem is known by Nissan who refuses to fix the issues. To prove the issue is larger than Nissan admits, choose transmission repair shops in any area, make a phone call and tell them you own a Nissan Frontier, you will need say no more, the shop manager will without prompt say "you have transmission issues due to the radiator contaminating the transmission, you will have to rebuild/replace the transmission. " it is up to the NHTSA to protect the consumer from fraudulent companies such as Nissan. A recall is the only course of action. . . Most consumers cannot afford the cost of a transmission (upwards or 7000 dollars) and will drive their Nissan regardless of the danger the transmission slippage causes. It is now time for the recall before someone is injured or killed.

I had driven aprox 20 miles on interstate when I noticed when truck shifted between 4th and overdrive the motor was racing. I turned off cruise control and turned of the overdrive with the trailer switch. I stopped at station checked fluids but everything seemed ok. When leaving station the transmission was slipping when shifting. I was able to drive it home. Next day transmission shop told me transmission would need to be rebuilt. After google info I told shop to also replace radiator also. I got the truck back 2 weeks later. After 5 days of driving while traveling home from job. Transmission locked up and truck came to stop in middle of road. I looked under hood and found oil in radiator. The truck was towed back to shop. Come to find out the shop had replaced with used radiator. The same thing had happened again where antifreeze mixed with transmission oil causing extensive damage, still in shop and waiting on its return. Spent 12000 on truck and in first month. 400 miles and 3000 in repairs. And still climbing.

Tl- the contact owns a 2007 Nissan Frontier. The contact stated while traveling 55 mph the transmission started to slip. The vehicle started slowing down and making a grinding noise. The vehicle was taken to the dealer who stated that the coolant from the radiator leaked into the transmission and caused the failure. The failure and current mileage was 104,000. Rvk.

My truck began displaying symptoms of catastrophic transmission failure. For example, gear slippage and shuddering as if rolling over rumble strips. I took it to a mechanic and they found the coolant had transformed into a thick pink substance. It was determined that a seal had failed in the radiator causing coolant to mix with the transmission fluid. This then baked inside the transmission. We replaced the radiator and so far have delayed the inevitable replacement of the transmission. I called local Nissan dealerships and they know about the problem but declined to offer significant information. I contacted Nissan and because of language barriers, etc. , they would not address my issue. I contacted the bbb and a Nissan representative eventually called me, but in the end disregarded my issues with mock concern. I contacted the mn attorney general and they said I might take them to small claims court. It seems that Nissan has concocted a warranty that only benefits people who experience the problem at a very premature stage.

My transmission is slipping. I have been told by a dealer I have radiator fluid in my transmission fluid. Apparently, this is a known problem with certain model year Nissan vehicles, due to a break in a transmission line that runs through the radiator. Please force Nissan to recall and repair this issue!!!.

Automatic transmission slipped when changing gears. Also it felt as if I was driving over groves in the road while driving. I took it to my mechanic who informed me of multiple problems with the radiator leaking into the transmission and that I was 4k miles over the extended warranty. I never even knew I had an extended warranty, I guess Nissan didn't want too many people to know even though my vehicle is registered with them. My mechanic said this problem was a known issue with the Nissan design and since it was past the 80k mile warranty it was not covered. Radiator was replaced. I called the Nissan dealership and they would not extend or honor any warranty. My mechanic told me to watch my transmission, because that will be the next to go. My only hope is Nissan does the right thing (forced if necessary) and repairs or replaces what is clearly a faulty design. This has the possibility of causing accidents at the worst and abandonment on the side of the road of a family at best. Get them to fix this issue and protect the drivers on the road please.

Was parked at store with truck running when it ran hot. With further look it was the transmission oil mixing with the coolant. Replaced radiator. Now transmission is slipping and now not pulling.

The contact owns a 2004 Nissan Frontier. The contact stated that while driving approximately 40 mph and traveling uphill, the transmission slipped after the contact depressed the accelerator pedal. The contact stated that the defect was also present when driving downhill. The contact had to shift to neutral and back to drive before the vehicle would respond. The failure was recurring only when the engine became hot. The vehicle was taken to the dealer but the failure could not be duplicated. The vehicle was not repaired. The manufacturer was notified. The VIN was not available. The failure mileage was 90,000.
