Tranny First of all, did you rebuild the tranny ? if so I assume you knew what you were doing, if not I would take it back to the shop that rebuilt it. Also did you change any tranny parameters in the PCM via LT1 Edit?. If you did then install the stock Tranny program, but it does not sound like program issues, I beleive it is in the rebuild it self......

had the tranny rebuilt by a guy in my car club,he has always done awesome work,i was wondering is it a sensor like the speed sensor or something,i pulled it out and put the tranny back in myself,think i might have messed somewiring up somewhere,these codes are always linked to a perticular part in the tranny,trying to find out which ones
