Engine/Transmission (1994 - 1998) TC unlock lock strange problem.

[San Felipe Bob]

Ok

Here goes.

This is what my TC does while in 4th gear on the freeway traveling 60 mph.



1) TC Unlocks when I back off the throttle all the way. (like it's supposed to)

When I get back into the throttle to resume 60 mph the TC stays unlocked for a long time. (minutes not seconds). The amount of time it stays unlocked varies and I have not been able to repeat the amount of time by changing my driving.



It's driving me nutz!



Is there a solenoid in the transmission that might be going south?



I have a new brake light switch , new TPS, neither of these has made any difference.



How do I wrap the TPS wires to eliminate Electrical noise?



I'm about to call Suncoast and get their valve body and computer. .

Just can't afford it.....



Thanks

Try checking the temps sensor resistance (or signal). Unfortunately it is inside the case if you have to change it.

theres a temp sender in the line near the pan that may keep it out of lockup if its defective.

'94 & '95 only. Then they moved them into the trans. All the guys with newer trucks that want to add an accurate trans temp gauge buy the '94-'95 line.
