1997 4l60e problems..
Ok i have a 1997 4l60e with a fresh rebuild that me and a friend did. New clutches, plates, band, tourqe converter, shift kit and so on. it works great in all gears, shifts nice but in 3 and 4th it bump shifts. so anywhere from 60 to 120 kmh it will do this. But only at slight acceleration or if you let off and let the tranny freewheel and then apply a light amount of gas. if you get into it it down shifts and works like normal. I have changed the fluid since the rebuild as well as check all the selinoids. Does any one have any advice. Thank you Jayson.
