2500 Yukon...How to Beef Up Trans??

[joegraz]

I am about to install a Whipple Supercharger and I am concerned that the trans will be the weak link. Does anybody have experience in beefing up the trans?

 

Thanks guys.

Your 2500 has the 4L80E and is well suited to work with the charger. You probably want to ferm up the shift points with the hand held programmmer they supply with the supercharger package.
