I've had my transmission replaced once and rebuilt twice in 36k miles. First was at 16K miles-all gears except 1st and reverse gone. Next was at 26k miles. Gears 3 and 4 gone. Next was at 36K miles last month. Gears 3 and 4 gone. I have just about every other oil change they have had to fix the transmission. I have owned this since new and never use it to tow.
the messed up part is my friend is having the same problems with hers 64k tranimission shot and 10k later its gone again. She doesnt beat truck and is so fed up with it, its going back to the dealership and she is getting something different!
