HP Tuners and the 6L80 part SIX - TCC desired press, max press, apply ramp, reg gain and reg offset
This is the SIXTH video from a seven-part video series covering what the calibrations actually do in the 6L80/90 transmission. As you will see in the video, I have outfitted a 6L80 transmission with pressure sensors for each clutch and I recorded the pressure readings while shifting the transmission on our Superflow Dyno. I recorded baseline runs and also single modifications using HP Tuners.
In this video, I show how modifying the Torque Converter Clutch tables alter the transmission pressures. This is probably the most common modification in the 6L transmission. There are many torque converter failures out there, so knowing what's going on in this transmission is important. In this video, I cover the operating of the hydraulics, electronics, and I even show you in the inner workings of the 6L80 JMBX converter. I also cover what these modifications do to the pressures in the torque converter.
In the video, I summarize the results for each of these calibrations. For a full report of each shift and each clutch, access the presentations and the raw files through my website at:

    Thanks for this. I ordered the parts using the Amazon links you gave. I just happened to have a vacuum pump exactly like yours. The needle on the left that you adjust to 5 inHg is too restrictive to go below about 12inHg. Drilling it out looks problematic. I have 1/4” ordered and will adapt. I’ll let you know how it works.

    This is great. If you wanted to improve the accuracy of the accelerometer at picking up high frequencies, you want to use a stiffer bonding material. Hard Resin is better than glue. Using the usb cable is a good idea because of the shielding. Also, for the frequency, I like to run the frequency spectrum to see all frequencies. Sometimes you have a shaft issue, for example, but also have a bearing worn that is really hard to see unless you look at the spectrum.

Cuz am afraid to pay money for programming then if it doesn't work then you waste the money for nothing. Thank you

    I remember years ago it was common to recommend drilling the pressure drain back it the pump cover to in theory help prevent converter seal “blow out”. I did see that happen once or twice waaaaaay back especially after an overhaul. Lately I don’t see that recommendation in the shift correction kits. Is there a reason for this? As in it’s just not needed or has that modification been shown to cause an issue? I do add a bit of Locktight to the converter bushing/seal and always use the seal retention plate as well. Just curious. I am working on a 94 non-PWM 4L60 now and was considering opening up that passage but something made me stop and think about my question.

    Hello, thank you very much for your great videos, they are really cool and greetings from Germany, I have a problem. I hope you can help me, I have now installed a new replacement gearbox with converter 722.640 and now I have the problem, before the car shifts into second gear when driving off, the torque converter clutch slams in. So it closes too early/quickly and opens too late. What's going on? The PWM valve has already been replaced. Glycol test is negative. It's an S211 E270CDI.
