I am having problems with the shifting of my tranny
tranny, It has been replaced 3times under warranty by the same guy and have the same problem with the shifting everytime and he kept telling me my TPS was bad and i have changed it and it fixed nothing.

When i am driving the truck at 1/4 to 1/2 throttle it shifts good and locks up like it should, but when i give it more throttle say to pass it jumps gears and revs up high and stalls. When it does, i will left off and ease back into it and it will shift fine. It does the same thing at any speed when i give it more throttle.

 

TV cable is not appropriately adjusted .. see You tube .. a few vids there to show ya how its done
