Hi Gents,
I have an I2030 installed on my 2002 LB7 Duramax. When running on the two economy sport tunes it runs great, except when I wide open throttle and the truck downshifts to 3rd from 4th or 5th, it will rev to redline then will not upshift again. I will stay in 3rd gear unless I shift it to neutral and then back to drive. I have not and probably will not run it on the maximum performance tune as I don't want any over torque issues, just want to offset some of the bottom end loss I experience with 5" exhaust.
When this occurs it does not throw a code or limp mode the transmission. Suggestions?

Re: Economy Sport Shifting Issue
trans is not holding the extra torque....look into a rebuild.
