Ive seen a few problems with them but not bad... Had a few that the tcm's going out.. couldn't communicate with it and trans was defaulting into gear.. Also seen one with a huge burr on the 1-2 relay valve causing it to shudder hard under acceleration and when shifting into second gear.. Just replaced the control valve body assembly.. But other than that I havent seen any comming apart yet... Seens to be a good tranny so far...

I have one in my 00 RCSB behind a L92. I have the problem mentioned above from time to time. I just need to get time with John from Speartech to sort it out. The 6L80E defaults to 3rd gear when it is in limp mode. No need for a converter for sure! The engine revs like it is in neutral with the 4.02 first gear and 3.73's. First gear is done around 35 mph and second at around 60.
