shift points

[shawn prellwitz]

i just installed efi live autocal on my 2015 duramax and it all went well.
i did the tow tune. the only concern of mine is the shifting on my transmission?
it goes through 5 of the 6 gears at 3000 rpm in a very short time.
i assume this it not how it is suppose to shift. anyone have this issue?

The ecm doesn't control shift points. The TCM tune would have to be changed using the autocal for the stock shift points to be adjusted. I'm assuming that your autocal was a ecm flash and not a tcm flash. If you did order a seperate TCM tune, then i would contact your tuner with your concerns.

thanks idaho rob
youre right it is an ecm tune. do you think a tcm tune is what i need?
ive read that if i have an efi live autocal i wouldnt need a tcm tune?
