If anyone has any idea what would be doing this, id appreciate it BIG TIME!!
Between yesterday and today, when im cruising, foot on the throttle going one speed on the freeway, it keeps going in and out of OD...jumping rpms, but not slipping at all, in fact it shifts smooth and hard through the gears..
Any thoughts bombers?!
THANKS!

 

Throttle position sensor out of adjustment, throttle valve out of adjustment.

 

Sounds like T.P.S.

 

Okay cool! Is this an easy fix that i can do myself? or should i take it to a tranny shop?? i have a good one close by. Appreciate it!

 

 

Thanks for the vid! Before i saw your post, i actually took the throttle position sensor off and throughly cleaned it with electrical contact cleaner, and played with the little mechanism for a bit, cleaning it and loosening it up a little, also cleaned all the ground and re wired all the positives to my drivers side battery. AND IT WORKS!! My truck is no longer hunting O/D at 50mph+ and running smooth as ever. thanks y'all!

 

LOOKS LIKE THE PROBLEM IS BACK!! Hopefully someone can help me figure this out! Still hunting OD, tcc locking/unlocking at freeway speeds..
I replaced alternator, regrounded all grounds, put in BD APPS noise isolator, and even replaced TPS to find that it still had same issue so i returned the TPS!
Any ideas???

 

Replace the bell crank and bushings and make the tps adjustable or just delete it.
