Need a hand identifying...

I can cross a 2801534Y if you accidently put an extra 2 in the front. If that is it I am showing it to be a 68 and 69 transmission. Both show to use 2801295 for the lower valve body.

If this is your transmission and you still have the original engine in your car you likely will have a problem with the hub on the torque convertor being too big.
