There is also a shim that goes on the OD piston between the tranny and the OD unit. There are tools to make measurements to get the right thickness but most of the time (or most techs I know) just use the same one over. We had special tools at the dealer to measure it but just dont forget it if you use the same one over unless the shop you have do the OD unit gives you the thickness shim it should be. It looks like about a 4" washer with a 3-5/8" hole. Ron

Yes the front of the trans is a 727 , the main difference is the rear drum support is also the apply piston support that allpies OD , the govenor is in the OD section behind the OD assembly.
You need a special tool to open up the OD section , best to take the OD section to a trans rebuilder and ask them to go thru it for you , rebuild the OD section to DIESEL specs if you have a high Torque/HP engine ...
Thats Good News. Yea I Had Already Heard About The Spring In The O.D. And Was Planning On Letting A Friend At Tranny Shop Do That Part. Anyone Have A Link Describing All Of The Improvement Mods To Help Trans Last Behind A H.P. Engine ? Thanks To All. Tom

True a press is required, but so are the 2 special tools required to assemble the OD unit.

I have a cheap 20 ton press at home. Using it and a few pieces of steel made short work of that 800 lb OD spring.
Other than snap ring pliers I didn't need any special tools to go through my 518.

I used the shaft to build the OD section first. After the pack was assembled I slid the shaft in and out then put the assembly to the side. When the transmission was assembled I had no problems sliding the OD tail shaft into place. Maybe I got lucky?
