Im new to this site so sorry if this has been asked, bought a 94 with a 373 gear , rebuilt trans-Shifts too hard! and 2400 stall speed, pcm was reprogramed for mods, tcc never locked up with this trans so i wanted less firm shifts-rearend taking a beating and a lockup converter, had a donor 94 caprice lt1 lying around from another project so swapped trans and converters, trans works fine but still no lockup checked tcc sw on brake and its ok called pcm programer and asked if they disabled tcc but they couldnt tell me and they dont have lt1 sotfware anymore, just want to know if possible to disable stock pcm tcc , if not than will tcc not locking up set any codes/lites? and can it be re-enabled Thanks

 

I'd start by re-installing the stock program, to determine if it's a software or hardware problem.

 

I dont have access to any program changing tools, if i put back to stock than id lose speedometer calibrate for 373, my question was was it possible thru programming to completely disable tcc?
