Anyone want to have a look and see If i am missing anything before I tear into the trans. Wont hold in 2nd gear. no codes . Gen 3, LS2 with 4l80e. PSI conversion harness and PCM
mild stall convertor. Still needs some engine tuning but trying to get the trans working first. Speed sensors and solenoids have been replaced. Still same problem. Thanks for any input
i'm not sure what you mean by 'wont hold in 2nd gear'. it looks to be shifting at the correct time that is set up in the shift table. what RPM converter? also seems the TCC is locking right after it shifts to 3rd so that could make 2nd feel way loose compared to 3rd. I would up the 3rd and 4th lockup speeds.
what I mean is it will hold under very light load but slips under part to full throttle. Ya I will raise the lock up speeds Thanks for looking
it did look like it revved a bit after shifting but you also gave it more throttle....thats why I asked what rpm converter....couldn't tell if it was converter or trans slip.
