I have an 09 Challenger R/T with a predator diablo U7135. I recently updated the diablo to the latest F/W and now don't see an option for changing auto stick features. Anyone have any ideas?

Shift points are preset. Normal shift points are raised slightly with custom tunes but I don't think you can change the autostick upshift. It's pretty high to begin with. I'ld be scared to set it any higher.

I'm having trouble with this myself.

2009 and up..... the only tranny options that work is the increase shift firmness, and "clear" TCM adaptives'. I just saw a forum post that Diablo is close to getting a few things worked out for 2009 + autos.

You can only disable the auto upshift on the '08

The posts above are correct. You cannot disable the auto up-shift on 09's and newer with the Predator.

You can disable it by buying the Mopar Performance TCM. That's what I did.

It cannot be done. I also had to get a 07 MTCM to get gear hold. We went over this about a year ago in detail. My rev limit is raised in the cmr tune.
Guess there close to solving the mystery. All good.
