    That wire handle on the back hangs nicely on the steering wheel when going straight! Mine used to spend a lot of time there after I first got it.

    Learn something new everyday, now is that on a NBS or NNBS?

    NBS, no NNBS to try it on, so can't comment on that one.

    What exactly does a Trans Relearn do, and how long does it usually take for it to learn?

    SERVICE FAST LEARN ADAPTS

    Service Fast Learn Adapts is a procedure for 6 speed automatic transmissions in which a series of tests are run to allow the transmission control module (TCM) to learn individual clutch characteristics. Once the clutch data is learned, Service Fast Learn Adapts translates it into the adaptive data cells, which the TCM uses for clutch control during shifts. The scan tool provides initiation of the Service Fast Learn Adapts procedure. This procedure is to be used following transmission repair.

    The Service Fast Learn Adapts procedure must be performed when one of the following repairs have been made to the vehicle. Failure to perform the procedure after one of the following repairs may result in poor transmission performance, as well as transmission DTCs being set:

     Transmission internal service/overhaul
     Valve body repair or replacement
     Control solenoid (w/body and TCM) valve assembly replacement
     TCM software/calibration update
     Any service in response to a shift quality concern

    Justin @BlackBearPerf did it to mine twice during the tune and it made for some freaky feeling 1-2 shifts, like a long slide into 2nd.

    SPS programming updates on 2007+ vehicles via pass-thru mode....

    I know TIS2Web is a subscription service, but are you able to see if there are updates before buying the subscription?

    Well, TIS2WEB shows you what's available for your VIN and then you go to ACDelco's TDS website to get the actual data. I guess you could compare the part numbers of the programs you can pull up in your truck through the Tech-2 to that which is shown on TIS2WEB, I don't fully get it 100% myself as I haven't used it yet, just poked around and am a slow learner.

    yes, there is a tool to put in your vin and then compare those to the existing calibrations

    I'll have to check that out. I did go to the ACDelco TDS site and looked at subscription prices and created an account. I actually fogot about the TIS2Web.
