Dad's 64

Hey guys,
Sorry in advance for the long post, but I'm banging my head against the wall with my dad's '64 Belvedere Max Wedge clone. Quick background...The transmission is a push-button 727 with a Cheetah reverse manual valve body. It was built about 30 years ago and has probably been driven no more than 2500 miles to cruise nights over that time. It was behind a mild 383 with a low-stall 12" GER converter. About 5 years ago he got into an accident with the car so it sat unused as it was being worked on. We just finished putting it back together after the bodywork and paint, now with a fresh 440 and a 10" 3000 RPM stall TCI converter. A local shop put finishing touches on it (breaking-in the motor and taking care of other details, including a transmission fluid/filter change and a band adjustment). When we got it home, we installed a deep Trick Flow pan because the chrome one on the car was leaking from a warped flange.
For a couple of trips around the block, everything seemed fine with the driveline. The next time we took the car out, it started locking-up whenever shifting into 2nd gear. It almost felt like you were putting your foot on the brakes as soon as you hit 2nd; the engine would labor like it was under a load and the car would come to a stop. If shifted into 3rd or back into 1st, everything was ok.
I read in another post where someone having the same trouble brought the revs up higher on a 1-2 shift and the issue cleared up. We tried the same thing with the car on jack stands and it seemed to "fix" the issue. But that was short-lived, as it started locking up again on the next ride after about a mile of driving.
After reading a few more posts here and on other sites, this past weekend i re-adjusted the bands (tightened to 72 inch pounds then backed-out 2.5 turns) and adjusted the shift cable according to an old Chrysler service bulletin. Note we found some clutch material in the bottom of the pan but no metal to speak of. We started it up on the jack stands and 2nd gear shifted fine (figured we nailed it!), so we let it run until warm to get the fluid to the proper level and then shut it off. About 10 minutes later on the restart, 2nd gear started locking-up again.
Appreciate anyone's thoughts on what's going on! Hoping we don't need to pull the trans...
Thanks,
Andrew
