Which TPS are you measuring by; there are two comming out of the TPS. One is for the tranny computer and one is for the ECM. And, they are in reverxe of each other. Send me your email and I will send you some info.Jimminyc said:

Are you maybe adjusting it the wrong way? By the way you described it, you are loosening both screws and moving the whole TPS to the left or right, not pivoting it on one screw at a time.

well, i tried adjusting it both ways...no matter what i did, the numbers didnt seem to make up 83%.
I dont remember which connector i tested...should i use the 3 wire or the 4 wire square connector?
Do you guys think my kickdown problem, and shifting problem, and TC lockup problem would all be signs of a tps??
TC locks up at 40 then kicks out when i let off the gas....wierd

4 wire square, and make sure you use terminals A & D (input) and B & D (output) divide output by input and there is your ratio. I would guess if nothing you do works, either you messed with the throttle stop, or your TPS is faulty.

Brandon, do a quick search. TPS adjustment. People have already posted the procedure a few times.
Now im trying to decide if i want to risk doing a flush or not....hmmm

If the tranny works good now, I would just replace the fluid and filter, but thats just me 
. No reason to fix what doesn't need fixing.
