Spent most of today cleaning parts while the flooring guys worked in my house.

Pressed in the shiny new output shaft bushing on my press.

Cleaned the case and governor in prep for paint and found some casting marks. With these, can anyone positively provide a date for my trans? I am only guessing on its age and intended use. The pictures match most of the 55-57 shop manual.

And, for those of your tracking the OD side, here's a shot of my damaged pinion cage. It is out-of-round and cut up from being jammed at some point.

I've ordered a new cage.

So, year and purpose anyone?
