Rebuilding the IRS
I've heard of where GM master techs couldn't get it right and your better off just getting a new one either from either the dealer straight from the factory or in a few choice aftermarket suppliers...
i'm trying to get my car ready for 10's this year and i fear that my tranny or rear or worse both won't last long.... I know who i can trush to rebuild my tranny... no biggie there.. but the IRS scares me a lil..
