trans trouble
 

ok so i put a ts six pos chip and some gauges in my truck. but when i turn the chip on its like it shifts really funny when taking it easy and when i give alot it seems to slam into gear. anybody know if my trans is just getting shot or is there some other problem. oh and the truck only has 76k on it

my 01 only had 61k on it when i chipped it and when towing heavy like i do everyday (20k-30k daily), if i smash the throttle it will shift hard and not smooth at all. had to deliver a load today in my buddies 05 6.0 chipped up,and it did the exact same thing. so idk if this is normal, but both of our trannies seem to be working fine otherwise.

Whos tunes are you running? If there wasn't a problem before you installed the chip, process of elimination to the culprit...

it ktperformance tunes and it shifted funny from first to second before the chip but only if i took it easy. if i mashed it it was smooth as could be

Is there a difference when the trans fluid is cold to when it is warm or is it just always?

It will or should shift firmer under WOT or hard accel conditions, should not bang gears.

i dont get on it when its cold and it feels like it slams gears but idk i have never rode in a chipped powerstroke other than mine. and when its on and i take it easy it feels like it bounces into the next gear kinda like if you would push the clutch in and out real quick on a manual

i know what feeling you are describing. my truck does it sometimes under wot with the chip in the 6 position (ts 140hp) and i didn't like that so i usually just dont run it that hard and i run it in the 5 position. in the 5position setting (110hp), it shifts smoother and under light throttle, very smooth. sorry i'm not much help...

I have the same problem with my trans on my 01. Going to take it back and see if it can be fixed this week but mine is better with the tunes than with the stock tune.

well let me know if you get it fixed
