    4L60E Shift-tiiming charts Y-axis are labeled incorrectly - how to correct them???

    My 2011 Colorado 4L60E "Desired Shift Time" charts make no sense. The Y-axis is labeled "Transmission Oil Temp" and the values range from 32.75F to 32.52F. All Pattern X, Y and Z, 1-2, 2-3 and 3-4 charts have the same "weird" labeling and values. See the example below.

    The Y-axis should have 1 > 2 shift, 2 > 3 shift, etc. What's the deal here??

    Perhaps an HPTuners guru could weigh in. PLEASE ASSIST!!

    Probably should email support directly for something like that.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Thanks for the reply.

    Don't the HPTuners "gurus" monitor the various forum sections and give helpful advice???

    I have used their e-mail contact form for other issues and seldom get a reply.

    Do you happen to know of a HPTuners specialist on this forum I could contact directly thru a post???

    You can contact them directly by opening a support ticket. Yes it seems like a pain in the ass, but they do reply, and you'll maybe be surprised how much work they will go through to help you solve your issues.

    I realize it's hard to know whether it's justified since you don't know if it is something you are doing wrong or just don't understand and should ask here in the forum, or if it is a genuine problem with the program they need to be alerted to so they can fix it. Just do a little research, looking at tunes from the repository to see if they have the same axis label problem, if yours is the only one, open a ticket. They really do want to fix things if it turns out to be something wrong on their end, even if it's just for one single year on a specific platform that only affects maybe a few users.

    Your advice is appreciated. I've only seen one other 4L60E Shirt Timing chart and that was for a Corvette. The Y-Axis, top to bottom read: 1 -> 2 shift, 2 -> 3 shift, 3 -> 4 shift. Listing "Transmission Oil Temp" from 32.75 F descending to 32.52 F, as my charts do, is bizarre.

    Do you have the link to the Tunes Repository??? I've been unable to locate it.

    Looking at your screenshot closer just now I notice something. Whenever you have an axis label that's underlined, that's an indication that you can click on the label and it'll open an edit box, and you can change the axis values. On most tables the labels aren't underlined and aren't clickable and thus not editable. You can change the temp values to match another tune that doesn't have the values compressed down like yours, if you can find one. You unfortunately can't change a scale that reads in trans temperature into one that reads trans gear shift.

    This is why everyone whines on and on about "POST YOUR TUNE". Which you didn't do. Someone, me, or 5FDP, could have opened it, looked at what you are looking at in much more detail than can come from a screenshot, found the editable-axis thing much sooner, and you'd be done and dusted by now...

    There's no 2011 Colorado in the repository, but both 2010 5.3L and 2012 5.3L have axis values, in trans oil temp, of:
    -40, 0, 41, 81, 122, 163, 203, 244, 284

    Its not an hpt issue, thats how the operating system is setup. It is still exactly the same, but allows temperature based correction as well. This is actually better than what is in most other files, which are simply gear/torque output. This is gear/torque output/fluid temp. Its just adding another degree of control

    Are you able to CLICK on the small letter "S" that I have circled?
    If so, the labels should change...

    That changes 'units' for the values in the cells, the issue here is the row axis labels (the vertical one, 'Transmission Oil Temp (*F)'). Note the OP's tune covers a range of only 32.51 to 32.75, and they aren't even linear, they jump around, though with such a small range they might as well all read the same 32.5*F.

    YES!!! Finally, someone who realized what needed to be done and how to do it. Thanks. I knew what the Y-axis values needed to be changed too but I tried selecting each individual value but they couldn't be edited that way. I never thought of clicking on the Y-axis legend itself.

    To what mbray01 was referring too, prior to about 2010, for a 4L60E, the Y-axis values were 1 -> 2 shift, 2 -> 3 shift, etc. Starting in 2010 (at least for the Colorado/Canyon trucks), GM converted the Y-axis to being temperature based. I didn't realize this until I downloaded tunes from the repository.

    Oddly, simply changing the 1-2 Pattern X Shift Time chart caused it to migrate the Y-axis value change to the 2-3 and 3-4 charts as well as all the charts in Pattern Y and Z. So I didn't have to go and edit them as well. Saved me time. Woo! Hoo!

    I described the very same click-on-the-axis-label thing in post #11, 2 weeks ago*.


    * '2 weeks ago' in stupid relative-time forum display, meaning some mystery unknown point in time somewhere between 14 and 20 days ago. GRRRR....
