Default Identify transmission

I have an 81 C3 and am wondering how I can identify which transmission it has in it. It's a factory 4 speed car but it doesn't have the original engine (has a small journal 327) so I'm not sure it has the original Borg Warner Super 10 transmission either. If I crawl under it, where am I looking for identifying marks?

This link is to an article on 78 four-speeds including the Borg Warner. Study the B/W photos to figure out where to look for the assembly codes. Then you can use the tables linked above to find the specific model. It also explains how to interpret the assembly codes you'll find. The VIN derivative you can check against the vehicle identification number tag on the driver's side windshield tag to determine if its the original four-speed to the car.

The VIN code on top starts with 1BS, so it appears to be the original Super T-10. Thanks!
