Hey guys, I have a 1972 C4 trans ( with 302 motor). It shifts fine in reverse but takes forever to go into drive. This has been an ongoing problem for about 6 months. It has gotten to the point that it now takes about 5 minutes to engage. I have changed the oil and while I was under there adjusted the bands.I know the problem is not band related but I figured I might as well adjust them while I'm under there. I have not done a stall test on it but I'm thinking it's time for a rebuild.
