Just about everything already mentioned.
I am going on my third transmission. I have figured out why the transmissions are failing. We have the Aisin Warner RE5F05A transmission, also known as AW55-50SN, and AF33. This transmission is in tons of cars including VOLVO, SATURN, and PONTIAC. Anyways, the transmission fails because of the valve bodies being warped due to excessive heat and wear. Our cars put 255ft lbs of torque to the flywheel. This transmission's maximum torque rating is 245ft lbs of torque. This is a complete Frankenstein disaster that was set to fail. This issue is very dangerous.
As most of you have all ready done, I have also put in a complaint to NHTSA, but their concern with the matter is about as good as Nissan's consumer affairs.
I took my car in for repairs and spent $1500 just in getting diagnostics done from Nissan on more than one occasion; transmission specialty shops, and electrical specialists. No one could find the exact problem except the transmission specialty shop who told me it's in the valve body design. Vague, but in a sense true. That's what actually sends the fluid where it's needed to shift the transmission.
I am currently working with IPT Transmissions to get a fix so we can have some piece of mind. NISSAN has put my life and my families life in danger, and once I confirm this transmission did not meet the specifications of the Stock Cars output, I will be getting a lawyer and be pursuing a lawsuit. My demands will include a recall for this defective transmission for everyone.
