I remember we had some problems with front drums when the trans did not want to go into third many times. I remember replacing the front drums with an updated one to correct this in some years but I forgot what years. Something to do with the finish on the drum causing the seal to stick some and not work right ? Ron I ran into this as well. Not the drum itself, but the finish on the high /rev apply piston inner surface. Never caused a 2/3 flare. trans just stayed in 2nd gear. Occasionally would shift 2/3 very late. Doug

the gasket and seal kits nowadays also comes with a revised inner seal for the reverse high drum as some were machined too deep and the new seal has a wider cross section. reverse normally will work because of the pressure applied in reverse but third gear can be quite iffy as to whether or not it will apply. the revised inner seal will normally rectify the situation. How did it do during air checking while assembling?
