The 6 3/8" 12 point bolts that hold C2/C3 unit together are broken?

The common clutch used in 1 and 2 is C-1, and it is not used in 3 and rev so that would be the one to suspect is leaking. I would assemble C-1 and then pressurize with air to make sure nothing is leaking. As long as the tractor is apart I would check C-2+3.They are used in 1 and 2 also, and in 3rd. which works OK for you. The control valve could have a leak, but I have not seen that problem yet. Keep us informed, Rod.

Also check the C1 feeder tube closely as they are plastic and will split which is hard to see. I always get the old style tubes from salvage/Elmer's when doing a powershift.

I thought the 90 series had 1/2" bolts in them after all of the problems they had with the 70 series
