833 id ??

The numbers really don't tell you much, but maybe this bit of info will help.

In reference to the first picture...

1. The "PP" stands for New Process (the manufacturer).
2. The next 3 digits, 833, tell you that it's an 833 model transmission.
3. The numbers after that are the date in Chysler's 10,000 day calendar.

To decode the deate you can go to the following website:

Note: Saturday July 29th, 1961 is Day One.

I believe, the numbers after the date are part of the VIN of the car the transmission was originally in.

The numbers on the other parts of the transmission are just casting numbers that from I have read in my research, really don't tell you much.

Also, the side cover can tell you a bit about the transmission too since there are two different types. The tail length can tell you if it's for an A-Body for B/E-Body.

The B/E body's are longer. Some have two shifter mounting positions, one for B-Body and one for E-Body.

I hope this helps.
