I have an 06 Duramax with 100k on it. A few months ago I installed a Edge performance chip, I have only used it on the economy setting.

The tranny started acting up and I had to put a transmission controller in. Has anyone had this problem and does it have anything to do with the chip. I have friends that beat the hell out of theirs and they have had no probs.

thanks for your help

I was getting a P0700 and P0708 on the Edge, and when I shifted to drive the shift indicator on the dash went away, and it would not shift out of first gear. I swapped out the nuetral safety switch and no change. I had the shop down the road look at it and they said it was the trans controller. I had to have the dealership put the controller in and they made me remove the chip before they would do the work. When I did that, it removed the code that said the controller was bad so I had to eat several hours of T-shooting @$99 an hour. I don't think it was the chip but I thought I would ask you all before reinstalling it.
