Hi I got a 1996 Camaro that I just put in. I built the trans with a Jake’s d3 valve body and everything works great but lock up. I originally put the pwm solenoid wire in the s spot at the trans and had lockup as soon as it shifted to second so I assumed that the non pwm solenoid wire should be use so I swapped them at the trans and now have no lockup. Is it in the tune? Wiring? Any advice on proper 4l80e setup using stock lt1 ecm would be great.

 

Well, if it was working then you moved a wire, that should be your clue..

 

So I have the trans tuning all ironed out besides lock up. Using the tcc enable wire not pwn the clutch engages and kicks off and repeats this cycle ever second or so. Using a tech 2 commanding the tcc it works fine so I assume something in the tune is wrong. Any lt1 4l80e tuner recommendations or anyone think they can point me in the right direction.

 

What year is the transmission
