Ralph, et al -
Really bad news....this unfortunately is the case. I did the same
swap, late model single rail w/OD into my 72 and sure enough it would slip at
the same circumstances you describe. This was the general consensus at the
time:
Taken from page 29 of the Kipping catalog, second edition, July 1995
A few units left with badly made one way bearings, funny noises and
slipping when starting off (original fitment 79-81 cars). If unit behaves
very differently when hot and cold, the cause is the solenoid, not easy
to repair.
I would add to this that the symptoms become almost predictable, such as a long
freeway cruise in O/D, followed by a complete stop at the exit. Slippage will
more than likely occur should the clutch be let out too fast and the stomping
of the gas pedal is a very likely contributor. I have decided to live with it
for the time being as I grew tired of pulling the trans (after the fifth time).
I will have it rrebuilt when the shell goes in for paint (prob'ly 98).
Please keep me posted with any further info you should come by and/or
recommended rebuilding sources.
Good Luck
