Transmission Gear Slipping problems of the 2007 Nissan Frontier

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.

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.

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.

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. . . .

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.

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.

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.
