i have a 10 spline 5 speed borg werner tranny. reverse is where 1st gear should be it has a 3.5-1 ration and is 2wd it was in a 90 gta does anyone know the specic name this tranny might be or where it comes out of. i think is a truck tranny it is pretty oval in shap no flat sidesand it does disconnect from the bellhousing with for bolts in a square pattern. Shifter is not like a t5 it goes in the top of the tranny with a circle bood and a wire ring holding the boot closed
