Transmission fluid mixing with coolant in radiator!.
Truck started not engaging in reverse at around 50,100 miles. Took my truck to larry h miller Nissan where I paid 157. 00 to have them tell me that my transmission was over full. They pulled about 3 liters of extra fluid from tranny. The fluid appears darker but thinner than normal. They said the pump is probably blown due to excessive pressure from the added fluid. This transmission has never had service of fluid added. No sure at this point if this is a problem with radiator cross contamination but about 3 yeas ago my heater stopped working. I checked my radiator to find it several quarts low. I'm not sure I want to spend any more money with anyone, especially Nissan, to have this looked further into, but I would bed that it is a cross contamination issue.
At 27,000 miles the clutch started slipping. The vehicle was in motion on I-5 freeway. The problem caused me to pull over and get off the road as the vehicle could not go at the speed of the traffic creating danger. The next day I took it to a repair shop where the clutch and the flywheel were replaced.
My clutch keeps wearing out after approximately 25,000 miles. I bought this truck used with 60,000 miles and replaced the clutch at 81,893 miles, 107,179 miles and it is now slipping again at 131,521 miles. I have owned and driven primarily manual transmission vehicles since 1975 and never had this problem before. I have driven nearl one million miles in vehicles with manual transmissions and replaced only one clutch. There is obviously a defect in the clutch that Nissan uses. The first time was 02/27/15 the second time was 5/24/16 and most recently 12/20/17.
Both rear axles are leaking at 60,265 miles. I was told this could lead to brake pad contamination which would reduce braking capability as well as the effectiveness o the parking brake.
Yea I got a Nissan Frontier new and my warranty is up due to 5 years but under 60000 miles and the transmission went bad. . Took it to the dealer and they want about 7500 for transmission replacement. . . I was driving next thing you know on the freeway I press on the pedal it revs high but doesn't go anywhere. . . This is so sad I think they make the car knowing that it would go bad after the short warranty I didn't fix my truck yet because the pricing is way too high to afford after buying the truck.
