4l60e Lock Up question
#11
Any dtc's? p1870? Used to see alot of these at the dealership and they always needed a valvebody, espesially 98-02ish...If you caught it early enough you could get it to lock up with the tech2 like your describing because that commands 100% pwm on the solenoid, unlike letting the pcm control the lockup where it starts out at like 50ish pwm (dont quote me on that its been a while) but its alot less than 100%, so you dont "feel" the lockup occur. The steel tcc valve wears the aluminum vb and slowly begins to not "hold" in lockup. I dont know about efi live but in hp tuners you could set the min and max tcc pwm to 100% so it always goes for full lockup, maybe try that and see what happens...this would only be a band aid but might help with diagnosis.

glad i could help, they make a repair kit for that so you wouldnt have to replace the valvebody, i've never used one but i believe its some kind of reamer and new valve and sleeve, i think they're less than a hundred bucks too...i'm sure someone here has used them, maybe they will chime in
