Anyone have a 4L80E program?

Baumann has a more budget friendly Transmission controller (yes they have one for a 4L80E too). Megasquirt also has 2 4L80E controller (GPIO and another alpha version based on MS2).

I used to have info on using the GM Diesel controller, but I can't find it anymore.

Baumann's stand alone 4L80E controller is $400 - just for the controller. That price is about the same as other similar offerings from other various companies.

With a harness, the Baumann is around $525. Cheaper than TCI, which is around $740.

Update - I've redone the trans shift pressures with a 2004 Caddy Escalade program, which changed things but still has the jerking. I then dropped 10 percent off from there, and this has worked wonders for it. I still have the problem, but the "window of opportunity" is a lot smaller and is not nearly as intense. Right now we have ice on the roads due to a cold snap so it's hard to really test properly.

Try adding Shift Torque Reduction back in.

I can give it a try. Question, if the number is larger is pressure greater? The wording in the information field for the base pressure is a little confusing. I'm also guessing that one attempt took the numbers too low, because on that attempt the trans wouldn't shift properly at all at WOT. That program has been removed.

The values for the shift Base Pressure (D0701, D0703, D0703) may range from 0 to 96 PSI. The higher the value, the greater the pressure.

The values for Torque Reduction (D0801, D0802, D0803) are the percentage that you wish the torque reduced on upshift - at a given delivered engine torque level.

Hi guys, update: I'm getting close. The guys at FLT actually had a buddy that uses EFI Live, and they had him take a look at the program. They didn't get it perfect, which I wouldn't expect from a blind program, but the tune is a lot closer than it was. I think I can get it the rest of the way. And in a couple of weeks, I swap in a new engine. I have a 4.8L at the rebuilders now, and it should be ready to start the installation around the first week of April. I can't wait.

If anyone needs a really good transmission built by guys that go above and beyond, Finish Line Transmissions is definitely my #1 recommendation. I am as satisfied with my FLT transmission as I am with EFI Live.

Thanks for the update.

FLT put very good quality/detail into their builds, and they have a very cool trans dyno.
