93 4L60e no reverse
Just bought this truck, reverse lasted all of about two days. 1993 gmc sierra 1500, single cab short bed, 5.7/4L60e.
bought it, was told it had a shift kit in it, truck is very solid into gear and quick between the forward gears. VERY solid into 2nd gear, enough to jerk the truck.
reverse at time of purchase was working, but felt odd.
Putting it into gear, it would take anywhere from 2-5 seconds for it to find reverse, then it would be a weak engagement for a few seconds then a more solid engagement. I drove the truck home ~45 miles, worked on it some, and put a thermostat in it since it was never getting up to temp, and that first drive when it was getting up to 195ish was when it quit. It would drop the rpm slightly, but it was effectively a 2nd neutral.
For about 3 days after, if it was cold, I had reverse. Now, with fresh fluid and filter, it's got basically no reverse whatsoever. it still drops the rpm slightly, but will not move backwards at all. All forward gears still feel solid. video is from when I pulled the pan down. Ideas on how to fix this? or is it just hosed and needs rebuilt?
