    Does the speedometer eventually start to read? Is the PCM2000 reading a correct speed input? What parameters do you have it calculating for speed?

    Have you played around with your trigger levels...

    Did PATC built that around July or August of 2012? If you post your file up, I will take a look at it for you.

    I assume he did that because he is not using Pattern A or B, and wanted to make sure they weren't conflicting with the shift.

    If I had to guess, I'd say it's an issue with it not receiving the correct vehicle speed or input speed on the trans. Can you see in the scanner where it's commanding a downshift? Are you able to...

    Can you log the event, so we can see if it is commanding the shift? The tune looks fine as far as transmission shift speed/rpm.

    I'm assuming this is a 2-3 shift that is giving you issues? It's...

    For some reason, it appears that it is not scaling your shift tables properly with the 4.10 gears and 26.00 tire height. I would start over with stock shift speeds, and scale from there. For...

    Your tune also has any sort of manual WOT shifts disabled (256 mph), so it appears to be functioning correctly. You can do some rpm calculations based on your rear gear and tire size, and adjust the...

    The torque converter stall speed is determined by a couple things, but most directly related to engine torque, and cannot be changed in the tune. A stock converter on a 4L80 is around 1800 rpm. ...

    I see that the current file has the rev limiter at 6600 RPM. How high are you able to rev the engine?

    Have you already updated the tire size and gear ratio in the tune? Anyway you can make a log of the problems you are experiencing?

    The current tune has lock-up engaging at between 50-60 for most light driving areas, so that makes sense. Unfortunately, with the lowered shift times and increased line pressure, you're going to...

    Jeff,

    That code is for a shift solenoid. Could be a bad solenoid or wiring/connection problem somewhere.

    The current trans tune looks good to me. Is the transmission stock? I mean, 4L80 is probably one of, it not the best transmission GM has ever built, but that is quite a lot of power you added to...

    That does look a bit off on those two parts. Triag - Do you have an aftermarket converter in there as well? Another thing I am now noticing, is that trans temp jumped up 20 degrees in that short...

    If you can post your file, I can take a look at it and see if anything looks out of place. A log of the stacking shifts would help as well, but not entirely necessary.

    0-20% is coasting/closed throttle, so it's entirely up to you if you want to adjust them. For 1-2 shift, you're right, and you probably won't be under 20% throttle for that.
