Got a '95 LT1/4L60e in my '76 and when in "D" and just cruising, everything is fine, but when shifting manually at the track, 1st to 2nd is a good solid shift, but 2nd to 3rd takes "forever" after shifting to 3rd. If left in "D",1st to 2nd is good, but I'll need to let off on the gas to allow it to get out of 2nd and into 3rd...
Do you think this is a programming issue? There aren't any DTC's in the Tranny...
It is a known problem with the 4l60e.extreamautomatics.com can help you out.They work the valve body and enlarge the valves and can cure that problem and many more
