- he might have some insight. My friend used to have a 92 Lumina with a 4T60 that had this exact same problem. It had a ton of miles on it and I don't think we ever figured out what was causing it. He just drove the car like that until he did a 3800 SC swap and used a 4T60-E.
I do recall that while he had the 4T60, he always had to put it into neutral when coming to a stop and then shift it back into OD to get it to go back into gear when he had this problem. It never did leave him stranded though - he drove it for a long time with this issue.
