F2 back in its hole, snapped together nice and tight
New F1 (21.46mm) vs worn down F1 ( 21.39mm)
Get in your hole!
Verified they all locked clockwise and back on the organized shelf they go, waiting on more parts to come in

Alternative 722.6 ATSG 93 page manual
This Manual is referenced in the other 120 page 722.6 ATSG manual. Figured it was worth posting up as it houses more info on the valve body and function.

Soak'em if you got'em
Decided a 1 week+ long bath time couldn't hurt, I will rotate the bags every day or so to ensure it seeps into all the stacked clutches. Inner bag has all the air sucked out so it's nothing but clutch's and shell 134 in there another bag just in case they punch through

Fluid plate came in for fresh sealing surface of oil pump
New to me, used $35 Rear Planet looked a world better than my chewed up rear planet. Verifying correct fitment of gearing

These transmission are a mixed bag of tricks lol
Here are my notes from when I took it apart. It is a mix of single and double sided clutches. From what I could deduce it should be the same in all 722.64X transmission
K2 clutch OEM 6 dual sided clutches 5.45" ID
B3 Clutch OEM 5 dual sided clutches / 5 OEM Steels
B2 Clutch OEM 4 dual sided clutches / 4 OEM steels
**** B1 and K1 use same clutch size alternating stack of single sided**** 20 needed total
K1 complete and matching 12 single sided clutches
B1 8 OEM alternating ID / OD notched single sided clutches
K3 clutches single sided OEM 10 total 5 OD / 5 ID notched
======================================
I am waiting on the following parts to finish
2 oversized snaprings
(1 shipped and will be here tmrw / FCPeuro is hopefully otw soon no update from them on 140-994-30-35 snapring)
Output Shaft Case Bearing (will be here in a few days)
Intermediate Plate (Need to go pick it up from local Trans supplier)
12 quarts of fluid

Last few to do items:
Get Fluid pump gear faces and pump housing taken down a few 0.001s" to ensure it seals well against the new pump place in the bell housing. (Local Machine Shop will be tasked this week/early next week)
Once that is done, it will be a long weekend ripping out the old and installing the new one, along with new motor mounts, trans mount. Finalizing install/adaptation. Then a flush after a long several hundred mile break in period.
Prepping to get this done in one of the next few weekends. Once I can get a dedicated garage weekend on the books.

About damn time I made some progress...
Resurfaced pump face...mmmm mmm mmmm
New Intermediate plate
Pump installed with new bushing
Time for clutches
A little extra fluid dumped in there won't hurt anything even if it spills everywhere and I have to mop it up later
All clutches are Soaked pretty good to say the least
Rear planet assembled and my bag of tricks in the background
We need more cowbell, I mean rear plant pics
K2 + Shell installed along with ring gear
Minimum spec clearance 0.15mm, everything mated up real nice
Needing that snappy Snap ring to finish
And in it goes after I dropped the parking gear in, thumb tight bolts per the manual attached to this thread
Rear planet fully seated
Stacking on a toweled empty cooler, input shaft + K2 inserted per the manual
Pretty sweet trick in the manual regarding using vise grips on the input shaft work like a charm to seat 1 half into the case
Sealant + Case bolts in awaiting front seal
Cleaned surface with alcohol
Seal in and dumped some excess fluid down the pipe
New output shaft ball bearings, shims all measured up and in below the bearing, snapping it up
Awaiting the final finish of punching it down after torque is met. I am going to fill up the torque converter to soak over the next few days off. Valve body needs to go on as well... we are getting somewhere now
I am planning on using some airplane stripper to clean the case and will probably just paint it flat black bc yea, stuff gets dirty under a car
Nommm nommm nommm
Input shaft moves, no binding, real smooth and all at the lower end of the clutch gap clearance spec
Wrapped it up in a garbage bag awaiting me to finish work on Thursday.... yea all the fluid I dumped in pee'd out everywhere. We live we learn. I just didn't want to clutches drying out over the next two-three days as it sits there waiting for more TLC

I was just referencing the main ATSG 120page manual in this thread along with another manual a friend who has rebuilt these puppies for 30 years lent me. (Thanks Gary!)
The 120pg manual is more than enough to get a rebuild done. I am just OCD about stuff and did not mind taking it apart about 3 or 4 times to make sure it all Spec's out perfect prior to final assembly in the case. I could have slapped it together weeks ago, but didn't want to chance any running longevity of the build using a "close to the limit" spec. Speciality oversized Snap rings were ordered, every thing else had the proper clearances when assembled.

Swap
Old leaking rear main
New seal gently tapped in
And up she goes
The aftermath of one long night in the garage, she is ready for war again
It has been a little over 250 miles and the trans is stout. I did a fresh adaptation of every gear change. Adapted the Tq Conv as well in Star. Honestly about 3-4 times working on shifting smoothness. Flushed the trans after 100 or so miles. Now it is time for another filter and fresh fluid and will be good to go
Thanks for everyone that chimed in during this process. I really appreciate all the help along the way.This was a fun project that I really enjoyed learning something new. I could not have done it without the confidence boosters or the information I received in this thread. Thanks for those that got personally involved to assist me in my endeavor.
