Any idea how to get a softer park to drive
park to reverse engagement
By this 0 to 102kph map on left that dont make sense it says 0 psi (at zero kph and zero tps) if im right ?

Re: Vr 4l60e help needed
Ive not done any auto programming and cant answer your but the table on the left does not say its vs tps. I think it might be calibration for the pressures in the force motor and shouldnt be changed. So at 102kph looking for 0 psi delivered it uses 0... pwm hz? something? and gets 0 psi actual pressure. The tables you want will be other ones.

Those tables would be road speed Vs TPS.
Most of my experience with Auto's is for the ecotec stuff so I'm not fully aware off all the different tables in 11p for transmission settings but I'd be looking for tables specific to 1st and reverse.
The main table shows 0psi at zero road speed and 0% TPS so that is minimum line pressure in the trans. There may be tables that modify the pressures when shifting.

Re: Vr 4l60e help needed
Could you try reducing the Force Motor - Pressure (PSI) Added to see if that makes a difference?

Thanks for the info tips guys.
Yeah next time i have the laptop hooked up may have to have a bit of a look around

Re: Vr 4l60e help needed
I’m not sure what it is named in $11 but in the later stuff I tune with it comes under garage shift. There is usually a table with half a dozen numbers with something like P-R, P-D and R-D along those lines.
Re: Vr 4l60e help needed
Hey everyone. On the topic of force motor I thought I would add another question.
I went racing on Sunday (1/8th mile closed street) , and on the gear change in the log I feel like it could have shifted a little quicker (log shows a slight spark cut ie limiter even though the shift starts to engage around 400rpm earlier)
Can I use PE force motor pressure vs engine speed to increase pressure above say 4500 and drop pressure below say 1500? My theory is this could improve the driving experience all around.
Similar to OP it is also VR 4l60e on 11p but a 355 in this one. And ran 8.9 on the 1/8th if anyone is interested - topping 2nd gear right on the finish line (again seeing spark drop just before the tps returns to 0%)
