2018 ZL1 A10 trans tuning?

[oldandnew2]

Have my unlocked TCM installed and pulled the stock tune out of the car.

First thing I noticed is there are no tables to adjust shift timing?

Looks like you can only adjust shit RPM and no way to adjust how fast the A10 will shift?

Is this common on the A10 gm transmission?

I'm using the VCM Editor 4.9.49 Beta

Well from what I've read on other forms is you have to adjust the torque request rate limits(Virtual Torque) to change shifting characteristics of shift fell.
Looks like is on the engine side of the tuning, not in the TCM......

Ill try to check this out soon and see if it works.

VT is a lot of it

VT is a lot of it

just to check if I am looing at VT? Am I looking at the right tables? or is there another table for VT?

vt is alot of it but, the more power you add the better its going to shift anyway. I know on my 19ss with the 10l80e you can greatly increase the vt at wot and it will shift way better but, it starts to adapt its way back down. The a8 doesnt seem to do that. There is definately shift time tables in the program hptuners just has not brought them out yet. My 1-2 2-3 shift at part throttle always shifts .3-.4ms no matter what so there is shift time tables that havent been uncovered yet.
