Does anyone know where I can find a gsl se transmission?

 

depending on your location availability can be slim, check rhinehart online. and just an fyi the 12a, gsl se 13b, and turbo 2 13b trans will all mate up fine to your vehicle.

check ebay and your local junk yards. with smog laws out there it has to be full of old rx7's.

 

No. The turbo 2 or "T2" trans will not bolt right into the car. Only the bellhousing bolt pattern is unchanged from 74 to the RX-8, but the similarities end there.

 

Your right. I should have said will mate up to the engine. As in they are all compatible.
