Got a trans shift table with some characteristics of a manual

[dlclarkiiRegal]

I'm very satisfied with these results, I love the way the trans upshifts and downshifts specfic to my driving style and I want to share

My trans table. I used a 2005 GTP Stock bin as a base (see below). I shifted the 3-2 and 4-3 cells to the left by one cell, in other words I copied the cells from 6 to 100% and then pasted those cells from 0 to 94% so it downshifts quicker with less throttle. I also hate when I slow down to make a turn and while I'm turning the trans downshifts and then after making the turn the trans upshifts to the gear I was previously in upon giving it throttle . So I lowered the 2-1and 3-2 cells at 0% so the trans wont' downshift when I slow down to make a turn. IMO my 3800 has enough low end torque to accerlate at 5 mph in 2nd gear and 10 mph in 3rd gear. It feels just like a standard transmission which is what I seeking for; slow down to take a turn and the trans stays in the same gear. And I raised the 1-2 cell at 0% to 30 so I can rev it from a dig and immediately take my foot of the throttle and it won't upshift to 2nd like a standard trans. I'll coast a lot, I'll give it gas to build up momentum and then I let it coast. And I can coast down a hill from a dig and it will stay in 1st until 30 mph. Lastly I raised the 3-4 and 4-3 shifts so there's no shifting while in boost (44 or more throttle). Very pleased with these results.

I have 3.29 gears for my 4t65 trans.

Dave, looks really good.
Any possibility you could post up the bin file of your tune?

I have a Feeling that my tweeking of my trans tune is not quite right.
With a copy of your file, I can run side by side tunes/VCM editor and copy & paste at will.

Please!!??
TY
Geo.

Save the file in any name you choose.
that way you will always have something you can go back too. You don't have to start all over. You can "jump in where it is set now".

Yes you can go in an make changes to what has already been "tweaked".
Every time you make a change save it with a new name.
I use the date and time and abbreviations of what I did as file names, that way if I make a change and don't like it, I can always go back to the previous setting.
It looks something like this: 1-1-12 MAF & VE.hpt
When you make any changes give the car a few miles and drive cycles to get used to it.
Before you make any other changes.

Check your release speed/settings for the TC.
