Rebuilding (and Modding) a GSLSE transmission?
 

how can i go about getting the needed parts to rebuild the GSLSE transmission? Mine is getting to bad to even drive spirited.

Additionally, the transmission is going to be backing up a 1/2BP NA 13b is there anything i can modify or improve for higher rpm applications?

you can go to any seller of factory mazda parts and buy anything you need.

You can buy my GSL-SE tranny to build so you don't have to take yours out. It even has a short shifter (actual short throw). It would be ~$100 shipped though, $80 if you want it.

If you have that tranny around still I may be interested...
