I have an ultramatic in my 53 Clipper deluxe that I believe is failing. I recently drained the entire tranny, torque converter included, thoroughly cleaned the filter screen and replaced all the fluid with type f, but it still has a hard time getting up to speed. I live in the NC mountains and think it would be easier if I had a manual tranny. Does anyone know what year manuals will bolt straight up to my 327 and will I have to lengthen or shorten the drive shaft.

I can supply you with a kit with every component needed to put factory stick into an Ultramatic car right down to the driveshaft and the yoke on the diff.

If your car has the normal 3.54 axle ratio then I would suggest straight three speed. To successfully run overdrive around in hilly country you need either a 3.9 or 4.1 rear axle, which I can supply also.

Or I can rebuild your Ultramatic.
