Mine is leaking and trying to decide weather to remove the gear adaptor and plug or replace the seals. No speedometer anyway, more strip than street. When I had my Trans rebuilt and upgraded, builder said to leave it in, but I can't remember why.

The builder probably told you to leave it in because he didn't have the correct 1 49/64" soft plug to seal the hole. The INTERNET, the MISinformation superhighway

If John K. says it can be plugged with the proper size plug then I would believe it. Do you have the speedo connection capped ? You can pull it and replace the seals or pull it and plug the hole, your choice.

CLOCK the speedo housing so the gear teeth does not mesh with the output shaft teeth. then it is sealed and not spinning and present for a later fix of the speedometer.
