I have a 07 gt. I have recently done some work the engine by putting a new short block, head & cams, supercharger, exhaust, clutch and other minor things. But i havent touched the tranny side except for a short throw shifter. Now ive been told my stock tranny wont last long. So im looking what tranny would give me the best bang for my buck and be able to withstand some horse power?

 

I'd get a viper spec T56.

 

You can also try to get a TR-6060 from a GT500.

It won't have the same gear ratio, but IMHO its a beefier T56.
