Ok. I'll change them to 0 and put the stock line pressure back in and see how it feels. Thanks for the info

Nothing compared to you guys. All my shift timings are set to .1. I know that it disables the adaptive learning to set to 0, but my tranny shifts beautifully with the setting that are in there and it has been running this way for 14k miles and at different times, it has had quite a bit of horses turning it. It's very firm under heavy throttle and sort of firm under light throttle. I have the transgo HD-2 kit and a vette servo. I'm reluctant to change anything other than my shift rpms. You don't fix it if it aint broke. These were the settings in there when I was using LS1 edit and Allen Nelson was doing most of my tuning.

If you have the billet servos, give up the fight to reduce that shift punch.

 

Indeed. You may just have to deal with this if you are using billet servos. I would personally not use billet servos again, after going through this same issue.

You could also try a regressive TQM strategy for part throttle/lower torque shifts.

 

Benkey, the # difference in are pressures and yours is, are's are labeled in metric and your are labeled in SAE.

 

Yep, my bust.

I drove it around and it feels MUCH better at part throttle. Pretty much stock feeling. I may turn it up just a hair. I just hated the 10mph neck jerk.

Since I have your attention...why does my truck increase rpm by about 300rpm when I shift from D to P and then settle back to normal?

 

This is some good info! I have been battling this issue with my brothers' trucks. The low speed 1-2 jerk. I have set the line pressure to 96 in HPT (max) and tweaked some other things. Sorry to hi jack but does anyone have any good HPT files with tq management removed and stock internals?
