Re: Transmission questions ('49 with R-9 overdrive)

OK, finally have the transmission back together. A neighbor / machinist was able to rebuild the mainshaft. He turned down the spacer slightly and used a heavy snap ring (almost double the thickness of the previous) so that and some Locktite retaining compound should hopefully hold everything together. The transmission also received a new rear overdrive bearing, 1st / reverse selector, reverse gear & several other sundries. I was hesitant about the Kanter overdrive bearing kit, however, it turned out to be well engineered and fit perfectly. The output shaft tailpiece was badly grooved so it was sleeved.
Had the Packard on the road last weekend and it was doing really well. Hit a long uphill section where it was in 2nd most of the way and the transmission became stuck in 2nd gear. Luckily we were able to manage it back to the garage and push it into place.
Pulled the top of the transmission fearing the worst. Luckily it wasn't catastrophic as the 2nd / direct selector had worked rearwards off of the syncro plungers and the plungers had popped out just enough to trap the selector. During examination the 2nd / direct shift fork was found to have some extra play that allowed it to move 'beyond' second. A new shift fork was found on ebay and installed this weekend. Hopefully the new fork and today's linkage adjustment will solve the issue. We weren't able to road test due to weather, however, it did shift quite crisply while up on jack stands.
