Yep that's the one-can't seem to find it any of the tranny tables. I know it's a 3.42 but when i compare files with other I-6's i want to see what the differences are in shift MPH before making changes-the factory shifting is lame.

I would think either HP Tuners or maybe EFILive or maybe Westers could answer this one. Those are some of the forum sponsors.

I have like 3 different files and i can't seem to find it anywhere-must be in the speedo table. I can't wait to start tuning-gotta get rid of the lazy shift syndrome.

I have 3 I-6 tunes modified from guys over at the HPtuners forum. Mainly looking at attacking the **** tables for better kickdown for more pep in city driving and on the highway. I find the factory shifting is very lazy.

I can undersand your dislike of the OE shift on the truck. The shift performance is night and day different on my Envoy after the Vector tune.

The gear ratio does not exist. You will have to enter those values manually.

When you say lazy shifts, you may want to raise the shift pressure tables to make them firmer. Is that what you are asking?

Raising the shift MPH will also make it shift at a higher RPM. WOT shift tables use both the MPH and RPM settings.



And don't overlook the ETC limit tables. They are a real hamper to the electronic throttle opening rate.
It's a great way to get rid of of the soft throttle rates.

What I meant by lazy shifts is the amount of time it takes the tranny to figure out I want it to shift. Say for example on the highway when I want to pass a car I literaly have to floor it to downshift-same goes for city driving-it always seems to be in the wrong gear and have the throttle just hang open before shifting into a lower gear to stay in peak torque.

So you are talking about the table " Base Shift Pressure vs. Torque vs. Gear - Performance"?

My table shows 90 in all cells. So you are saying bumping up the cells in the 1-> 2 Shift row lets say to 120 will firm things up?

Thanks
