I am a transmission specialist and owner of Cardinal Transmission Service in Columbus Tx. I built a 1997 S10 extended cab with a LM7 and a manual trasmission. I'm a total gearhead and have been for the last 20 years. I am, however, sort of new to any sort of PCM tuning. So on that note, I am grateful to have found this place and would be happy to answer any and all geartrain questions.
