Help!!!!
I"ll try to make this long story short.After A dyno tune My converter Intner ermitantly does not lock.I have HP tuners 2.0 and have been Up back and sideways trying to fix it.There are no trans codes setting.I can manualy lock it w/HP tunes scaner controls but the pcm will not lock it.And like I said sometimes It locks.I flashed it back To stock but had the same result.Any Body have Ideas?
ie. in 4th gear and any %tps lock-apply converter at 42mph and release needs to be less than 42---41mph
