    6L80E Rough Shift 1-2 and 2-1

    What is the pressure supposed to be? I’ve changed my driving style somewhat to avoid the shifting problem, but sometimes still feel a lag when getting into the accelerator, like when increasing speed through a turn. Sent from my iPad using Tapatalk

    DL3 Switches???

    Just needed to confirm this past part on the switches. The part numbers are the same for w/ or w/o DL3 option, 20835554? If it didn’t come from a DL3 vehicle, can it still be programmed by a dealer to work with the DL3 option? Sent from my iPhone using Tapatalk

    2008 Tahoe with DL3 RPO Code

    Sounds like a guy I need to know then. I do like the 2008 interior panels a little ore than my 2012 panels, for now at least. They have been on the truck for about 1 beer run. Sent from my iPad using Tapatalk

    2008 Tahoe with DL3 RPO Code

    Anyone have a 2008 Tahoe with the DL3 RPO code and brushed aluminum window switch bezels? Trying to track down the right bezel to be able to install the DL3 package in my truck. I got the interior panels from a 2008 to out on to my 2012 that were in better shape and. It broken and rattling...

    Programming DL3 mirrors at dealer...

    Gotcha. I’m guessing it’s through using the GDS2 subscription and diving into the settings for the DL3 mirrors. Too bad about the led stuffs, I hate hot hot the resistors get. Sent from my iPhone using Tapatalk

    Programming DL3 mirrors at dealer...

    Question here if I can revive an old thread. I have a MDI2 and would love to do this upgrade as well run LED’s without the resistors, how would I do flash the BCM to accomplish that? Sent from my iPhone using Tapatalk

    Level on 17's

    Considering doing the same for my Tahoe. I want to lift it slightly and level it, while keeping my 17’ and 18’ wheels (snow tires for Denver). Only thing keeping from going for it is the gas mileage impact. What are folks seeing in gas mileage before and after a 2.5/1.5 leveling kit? Sent from...

    MPG tips

    I’ve been tracking mpg on my vehicles for years too. Noticeable differences in weather, road conditions, 4wd vs 2wd. Just tried a tank of 91 octane (I usually use 87), and am planning on running a few tanks of 91 so I can compare notes. Sent from my iPad using Tapatalk

    Engine/Trans Tune Question

    So back when my granny was having issues, I took it to a tuner when modified the way the transmission shifted to try and smooth it out some. Turns out there was a mechanical issues, and $2k later the mechanical issue is fixed. Now to the problem/question. I think I can still feel the effects of...

    6L80E Rough Shift 1-2 and 2-1

    Finally broke down and took the Tahoe to a shop. They dropped the transmission and found the previous rebuilder mid-installed a snap ring when putting it back together. New clutch disks for 2&6, and some other new and improved goodies, and the Tahoe will be back home this weekend. Sent from my...

    Not yet, been crazy busy with other stuff. Hoping to dive into it next weekend when the wife is out of town, but that’s the same weekend college football starts.... Sent from my iPhone using Tapatalk

    6L80E Rough Shift 1-2 and 2-1

    I could not find them in the Haynes manual or the alldata website. Haven’t gotten with my buddy to look at the pressures with the tech2. Night be able to this weekend, but need to find a new car for the wife on Saturday. Sent from my iPhone using Tapatalk

    6L80E Rough Shift 1-2 and 2-1

    Alright, got the subscription to AllData, now where can I find the pressures? I’ve been digging around for a few days and cannot find that specific info. I did see a YouTube video that said anything over 12 was high, but that’s about all I’ve found so far. Sent from my iPad using Tapatalk

    6L80E Rough Shift 1-2 and 2-1

    Picking up a Haynes manual today on the drive home. My friend's tech2 had to be sent in to be fixed, so waiting on that to come back and we will dive into some trouble shooting. Anyway to do the Transmission Adaptive Pressure reset without a scantool? Or to find the pressures without a scan tool?

    6L80E Rough Shift 1-2 and 2-1

    Got an update on this one. The rough shifts are back. It’s almost as if the learning the transmission does brings back the rough shifts. Any way to disable the learning program of the tranny/engine? Sent from my iPad using Tapatalk

    6L80E Rough Shift 1-2 and 2-1

    Did you completely reset the engine and trans relearns? My father in law mentioned lots of folks go for the granny as the issue when the motor mount and the learned stuff can be a cause, not necessarily the tranny. Sent from my iPhone using Tapatalk

    6L80E Rough Shift 1-2 and 2-1

    Changing out the engine mount definitely helped. The trans shifted perfectly for a few days, but I am noticing a little hesitation once again in the 1-2 shift. He was also able to reset all historical codes that are deeper in the computer than an obd2 can read. My friend has a tech2 and just...

    I was just browsing the other day for a tech2. Only worry is getting a genuine one instead of a knockoff, but even some reviews of the newer knockoffs are positive. Sent from my iPhone using Tapatalk

    Funny you should mention it. My father in law has the virus edge by snap on, but my good friend has a tech2. I’ll have to check out AllDataDIY. Sent from my iPhone using Tapatalk

    Hey folks, been working trying to get my dash to look like the pics in port #83 with dual USB outlets. I have an aftermarket headunit, and one of my ports is now the USB connection port with the usb coming from the back of the head unit. I am hoping to find a way to have the other cigarette...

    6L80E Rough Shift 1-2 and 2-1

    another quick update on this one. The tune did not help the shifting issue. My father in law and I did fix the busted as hell motor mount, and that did help somewhat. Hopeful he can do some diagnostics today (teaches auto mechanics at a community college and has the snap-on tool he brought from...
