Just went to the dealer for some warrenty work and while there, I wanted to have the speedo/tranny upgraded for 265's. Dealer tried and said they couldnt do it. They said there was some kind of glitch in GM's system at the current time. Anybody else see this??

battered subject...


I have heard recently that some of the guys with LLYs and 265's were able to have it corrected....Never tried myself

Actually, I was thinking, I have a customer with LLY and 265's. Lemme drag him in, find out for myself if it can be done. Then if so, I can put the procedures togather for your dealer
