my camaro has a yank SS3600 converter and it started acting weird. It sometimes keeps the clutch engaged when i go WOT my motor falls on its face for a couple of seconds then it un locks and starts to pull? does this sound like a tuning issue or trans problem ? Help me out fellas , it dosent disengage the converter clutch with a half trottle blip like it use to...

 

Sounds like it needs some tuning done on it sounds like what it isif there's nothing mechanical wrong with it!

 

If you have a scan tool monitor the TCC and see if the PCM is commanding the TC clutch to release. If it is and you do not have a TCC solenoid code then it is probably a converter problem. If you do not have a scan tool you need to take to a shop for diagnoses.

 

thanks guys it all started after a h/c swap i had trouble getting the converter to lock so i had my tuner(set all the values in the idle, low, and medium misfire tables to 32767.) after that i had a good strong lock up but will not unlock under 1/2 throttle and sometimes dont unlock for a couple of seconds at wot.Does anyone have a similar set up that could send me a ls1edit file to copy? I have 3.73, 4l60e,yank ss 3600 converter

 

What happens if the tc doesn't unlock during a downshift? Does the tranny still drop down a gear or does it stay in overdrive? I just swapped from 2800 to 4000 stall with no change in programming and now have a weird vibration when downshifting at wot or even 3/4 throttle. Just wondered if this could be related to the same sort of problem.

 

check your TC bolts...

as for the TCC not disengaging? maybe Yank or Vince can chime in.. sounds like a solenoid or mechanical issue, it was acting "OK" immediately after the tuning correct? then it started acting up?

 

any one have a ls1edit file to compare
