i have been looking for a solution to the problem below for about 2 weeks now and still have not found a rock solid answer as to what it may be any help would be great

i have the 2.2 s-10 2wd the trans shifts rough from 1-2 and when the trans gets hot like when driving on the interstate shifts breifly from od to 3 or 4th then right back into od. i found a service bulitin that said that it is the valve body but i also know that the tcc silenoid goes out in these too dose anyone know what this may be.

i did pull the engine codes and it gave me a p1870 just trans parts slipping which is what led me to finding the service bulitin.

once again any help would be great thanks guys

 

ok so out of 120 people noone has anything to say about this can anyone please give me a hint on what the actual cause might be

 

Welcome to the forum. What I have to say, you probably won't want to hear. By the valve body, you're probably referring to TSB #01-07-30-023B which is almost 10 years old. As for an electrical problem on the TCC solenoid circuit (wiring or solenoid windings), the PCM will detect it and set another code. A new valve body may help but it won't do anything to worn-out friction surfaces. It's highly probable that yours is due for a rebuild.
