auto help can any one help with my problem,i have a std ls2 auto with original wiring harness and pcm (and gearbox tcm),i have had it oh a HP TUNER and it runs ok but it wont shift up the gears and it does not see any road speed,all the sensors are conected .there is a plug that we were told goes into the bulkhead harness that is not needed but it does need the pink wire to power the MAF meter,all the gearbox wiring is in the harness and dont know what we have missed !! been at this for two weeks now (i have tried a search) any advise would be grateful,
