When did GM go to the 6 speed??
What is wrong with the 5 speed?? Does it overheat or is it just not as efficient as the 6 speed?
I have heard before that the 6 is way better then the 5.
i believe 04 was the last year of the 5 speed
i the 6 speed can handle more hp stock then the 5 speed
and i would say get a lbz as well
