Default Re: Pictures, part #s, instructions; rebuilding a 39 style trans.

Mac's book doesn't cover the T-259 types but the gear portion is still pretty similar. A person should get the factory shop manual to work on the OD types. They come apart a bit differently and there is the whole OD output system & sprag clutch to deal with. Check the balk ring & gear plate for proper tension on the balk ring. Check the planetary gears real close on the R10 transmissions too. Mac can still help with parts on the overdrive types and he stocks a lot of good stuff. I always replace the heavy snap rings with his kit. They originals are a b!tch to get out and his are much better plus they are the correct thickness. He has a good thrust bearing kit too.
