Difference between 12a and 13b tranny?
Hey guys, I'm looking for a 13b transmission for my 85 gsl-se. This guy has one but doesnt know if it's from a 12a or a 13b motor. How can I tell the difference between the two trannies? Thanks.

Doesn't matter. Buy it and install it.

The 13B Tranny will have a Vent on the side of the bellhousing. The 12A one does not.

Thanks for the info. I'll probably get it either way cuz I'm afraid I'll need it soon. My current transmission is acting up...
