It also sucks when using 4x4 to get up a long snowy driveway. I can lock it into 4 low and turn the TC off, but once it really starts to spin, the TC will automatically override and kick back in. It's a ****ing PITA. Especially when you get home from work and can't make it up your driveway.
Between the e-locker and the TC I'm really hesitant to spend money on a 4x4 that will not override the TC when it's needed the most.
Has anyone had any luck getting a stealership to completely shut it off?
Today's test of my new ride was:
Traction control system completely active. I approached the snow covered dirt road from my long driveway, slight uphill grade here. Just as began my turn I hammered it. Back end started to slide out, TC dash light blinked, power shut down, slide stopped, power back. It happened so fast You could barely feel it. The rear end barely slid out and I was without power for no more than a second. I don't think I could have stopped a slide and got back under control with power faster just working the throttle.
I then turned off both stages of the traction control. Stopped at stop sign at end of dirt road ready to turn out on to snow covered paved road. Once again I hammered it. Fishtailed down the road until I let up on the thottle. Both rear wheels locked up. No power cut off at all.
Finished my 20 miles to work at 75mph on the interstate, traction control still shut off.
Reached work and turned in to a mostly empty snow covered parking lot. Hammered it again and did a few fishtails and then a couple donuts to verify that I still could after running at 75 on the interstate. Both wheels locked up, no power cutoff. No flashing dash light telling me the TC system was active.
The ONLY time I have lost power to the rear wheels is when I had not deactivated the TC system. Trust me, I've tried too.
One thing that I found out that was not really clear to me is that you have to shut it off in two stages. Hit the button and release and wait for the message in the message center to disappear. Then press and hold the button for a few seconds until the light flashes and another message will be shown. If you just press and hold just one time you are not shutting both levels down.
If I do that I have not been able to get the power shut down part of the TC to activate even after 75 mph runs on the interstate.
