Why do I have this feeling, that the next photos we see will be of a nearly New looking transmission. Btw, the rubber boot that fits over the clutch fork is available from DMCH. P/N 103151

Thanks guys! I'll try to make the transmission presentable...
Well, I figured out what happened. I remember that when the shaft nut backed off, I tried to shift into 2nd gear, and it went in hard. That's when I knew something was wrong. During that shift, apparently the spring that provides tension on the 2nd gear selector fork failed or jumped the roll pin and got caught up in the gears. This caused the symptoms of 2nd gear popping out, and a clicking/grinding sound. Pieces of the spring were in the selector forks, between the gears, and stuck to the case magnet....

The good news is that the gears are pristine, and the spring (part number 103220) was in stock at the DMC Texas store. What baffles me is while the spring failed, the infamous 2nd gear roll pin was unscathed. :wow: Nevertheless, I'll replace it with a reinforced (double) pin.

While I'm waiting on repair/refurbishment parts from DMC and PJ Grady, I removed the 2nd gear selector fork, repaired the slight damage to the shaft, and recovered the pieces of the spring. Props to Stephen Wynn, Rob Grady and their teams for their advice and service. Top Notch!!

I also picked up my flywheel from being resurfaced..

I also cleaned the case magnet and the mating surfaces of the case halves. Question: Do you know if the magnet is supposed to be slathered in grease, or was that just 36 years of buildup? I imagine that I have to put some on it to prevent it from falling out when I replace the case half.

Thanks,
The goo on the magnet is powered metal. Its fairly common to see that to some extent. The magnet is doing it's job by collecting the particles.

Make sure the 5th gear fork is not bent.
Parts arrived to allow me to proceed..

A gravity fed blasting gun arrived today that I bought from Eastwood, and I tried it on the bell housing. I used medium soda media, and it worked really well.

I also started to replace the seals in the gearbox.
Nice!! I actually bought the Harbor Freight version of that gun with sand from Lowes and did the same thing. I'm sure it was not as nice as the Eastwood one (ended up having to do some internet recommended modifications; drilling out holes to be larger and such) but it did alright. It's crazy the difference it can make.

(this is not the transmission from my car, it was one I bought from a parts car hence the crazy amount of grime)
Are you going to blast the whole casing or just the bellhousing? I primed and painted mine after blasting and now it makes it super easy to keep clean because the cast aluminum isn't as porous.
