WoodDean,



Jeff is 100% correct that the Borg Warner T-86 was NOT used in the '55 or '56 'Birds. In looking back, I THINK I picked that notion up from reading the reprint of the May 22, 1956 '1955 Thunderbird Package Book' (overview of engineering drawings and specifications) from Ford Motor Company. That document wrongly indicates that the standard and overdrive transmissions for the '55 'Bird were per Ford passenger car. After Jeff's input, I looked in the '49-'59 Ford Parts & Accessories Illustration and Text Catalogs.



The '55 -up passenger car transmission unit has a sheet metal top access cover and a front snout that is secured by 3 bolts. The '55 and '56 'Bird unit has a cast side access cover, shaped per your description, and a front snout secured by 4 bolts. As Jeff also stated, per the catalog illustrations, the gear teeth on the cluster gear run in opposite directions in the two different 1955 transmissions!



The more I learn, the more I realize that I don't know! THANKS for catching my error, Jeff. Appreciated!

If you are trying to keep your T-Bird totaly original and do not plan to push it at all the original light duty transmission will work fine. My personal preference if you want to stay with a 3 speed would be a fully syncronized 3 speed toploader out of a '63 and up Galaxie big block car. Bullet proof and syncronized low gear. Impossible to tell it is not original unless you crall completely under the car and know what you are looking for.
