Hi all. I have a 97 Corvette automatic. I encountered a problem after swap pcm 97-02. I swapped the wires following the diagrams. The car works well, except for the trans. In position D, the car starts from third gear and then shifts into 4th without locking the torque converter. If you move the slate to position 2, you can engage second gear, 1 does not engage at all. From the settings in tune I don?t understand some of the wheel size calibration values, is it possible that this could have some effect? Here are some photos from diagnostic devices and my tune. initially in pcm there was a tune for the trans manual. Could it be that manual 411 pcm cannot be made to work with an automatic?
