4L80E swap Problems Can you please look over this tune and verify that the segment swap did go through...?The car will start out in second gear from a stop( In drive on the selector) the car moves 15-20ft and will shift straight to third and lock the converter, to the point the engine will stall,feels very violent as if it were going to reverse.Feels manual 1st has nothing just revs,scanner says its in 2nd gear from park to 1st ?
I hooked the scanner to the car and commanded the car to stay in first and second with good results but as soon as I let the tune control the car it will act up, when the car shifts it does not see the mph to shift, seems to shift on time.Does the rest of my tune look ok ? Thanks guys
