I'm reusing my selective end thrust washer. Endplay checked out at 0.009". My article from Sonnax says 0.007" to 0.019".

I put together the remaining parts. The overrun clutch was a pain to install due to the double lip seals. I know some guys don't even take it apart, because it's difficult to reinstall.

I made a little block and used the assembly goo container as a carousel...the videos said you work the top lip seal and the piston just falls into place. Well about 1 hour later it finally did, but I had to work the lower seal with another one of those little round plastics. LOL

If the plastic rounds are difficult, make one of these. Copper tubing and .024"-ish wire.

I dropped in all the geartrain and pump. I have a little issue with the Transgo shift kit pressure relief plate. There's a plate that goes in the same location for the dipstick. I tried cutting a slot...

I may just tap and plug the hole on the valve body and eliminate the pressure relief valve mod...

I wound up tapping and plugging that hole for that relief valve. Got the electrical harness installed...just needs oil pan!

BTW, my oil pan didn't have a drain plug, so I added my own. Just a 1/2-13 bolt and nut welded to the pan with a nylon washer.

Alright. Transmission rebuild is complete!

I think I'm going to just keep running the unit that's in the truck for the time being.

Edit: On post #63 I mentioned the wider engine brake band. The ATSG manual said you also have to change the pin on the servo along with the band because the little engagement part is different. I couldn't find that pin, so I re-installed the original band.
