tranny question?
 

hey guys i know i should do a search but lazy right now!
i do some towing with the sut so i decided to do search on what to do to beef up the tranny so i found the 2 4 servo upgrade , so it just arrived!
the guy at the local tranny shop doesnt understand why i would be doing this/

what can i expect from installing this mod?

what tranyy does my 05 sut have too? i believe the l65?

the only upgrades i have right now are exhuast and k&N FILTER CHRAGER SYTEM.

thanks for the help
