    I recently had my ECM recalibrated / reflashed using T-SB-0373-09 (Transmission TSB dated Nov 3 rd.)

    Well now it's not possible to disable VSC in 4WD-HI. :eek:

    I used to be able to hold in the "VSC diable button" for 3 seconds while in park--now it does not work!

    I think this may be an unintended side affect of the ECM reflash. Can some of you guys with the 2009 4x4's confirm this for me?

    UPDATE: 12/23/2009 My problem has been solved.

    I confirm that my problem existed... Took my tuck to the dealer for diagnostics... My truck sat for a day... The SA said the tech did nothing. When I picked up my truck the problem was gone. I have tested the VSC disable switch while in 4WD-HI and the problem is indeed gone. Chalk one up to PFM.

    I just went out to my truck and started it up and put it into 4HI. Then I pressed and held in the VSC button. The light came on in the dash saying that it was off. Then I put it into drive without issue. I had the reflash done last monday.

    Thank you for doing that! I can't imagine why mine would be any different if they did the same exact reflash. I had the service advisor print the TSB so I know they had the right one. I am very concerned about this.

    Did the reflash make a difference in the shifting issue or not?

    As far as I can tell yes. I still think mine downshifts prematurely at times but I don't have that hesitation where it's searching for gears anymore.

    I tried it out as well and had the same experience as dexterdog. Doesn't seem to be a problem for me.

    After the reflash I noticed an immediate improvement during the 2-1 downshift. i.e. Slowing down to roll over speed bumps and then accelerating is much improved. My truck never had an issue with hunting for gears that others have reported, only the harsh 2-1 downshift.

    I was messing around on some trails six days ago when I noticed I couldn't disable the VSC in 4WD-HI. I was in the extreme backcountry, and I had nobody to communicate with to test this until now.

    So the Auto trannys are having problems as well for 09? whats the deal? manuals with revs hanging and autos shift hesitation/problems? My father has a 09 with the auto and hasn't said anything, maybe he is just getting too old to notice..lol

    My truck appears to be having a unique problem. I'll make an appointment to have it examined and report back here what happened.

    Thanks again to Dexterdog and NMG for testing and reporting.
