Go to HPT. tune repository and search for a 2004 and put 80E in the optional Key words. There are a few tunes in there, go to speedo and recalculate for your gears and tire size and adjust speeds as needed. I dont have a 80E or I would give you my trans info.

Here is a stock 4l80e file I suggest you start there and change one thing at a time.

When I am tuning part throttle shift points I keep in mind what gear I am in, and if I dont like a shift point I look at the speedo and see what speed it shifts then go into the trans table and turn that down a bit....kind of cumbersome but works really well.

lol, ok. Would it be a wise move to remove all TM from the trans?

That's kind of what I did for normal driving and WOT. It worked ok for the 22's but I still have to work on the slick setup. Changing from a 31.5" to a 27" changes a lot. I thought I had it dialed in but it was hanging up a little on the 1-2 but a lot on the 2-3.

I do the same. Helps to fine tune driveability. Fine tuning is best done one little bit at a time anyway.

That's how I built my trans part throttle shift points also. Anytime I think it should shift or not shift I just pay attention to gear and speed then change it.

Give this one a shot if you like. This is a friend of mine's 80e. I recalculated the tire and gear for ya and scaled the trans tables for 4.56 and 27" tires. You can try these if you like. As far as I've ever known the transgo shift kits need stock shift pressures and shift times to work correctly. But see how you like these shift speed tables.
