Home Forums Gear Hunting Trucks and Four-Wheel Drives Ford Tremor and 7.3 liter gasser

I believe that is it. We have it in our Suburban and did have it in my 2000 GMC 2500. If any of the big three had it in there 3500s at the time I would have bought that one no matter what. Love that option.

I hear what you're saying. My Tundra breaks the rear drive tire(s) loose a lot on wet roads, empty, and even on dry roads. Even at freeway speeds, at times. And it's not like the tires just spin, the ECU cuts fuel. This sucks. Although a minor complaint to some, it is my biggest complaint with the truck, besides the small fuel tank.

My 2003 GMC Yukon XL, which was a 3/4-ton, had 4-auto and it was great. The 4wd was partially engaged, and sent power to the front wheels when needed. Had an old Exploder, and although clunky, the 4-auto was functional. The owner's manual even stated that unsual noises might be heard from the drivetrain

I think the heavy duty trucks and Toyota skipped the 4-auto feature as they couldn't make it robust enough. But that is just my guess. I've heard that transfer cases with 4-auto are more difficult to make durable.

My solution for the Tundra would be to install a cone-clutch, limited slip. But, I don't know if it would be as good as 4-auto.

Yeah, we had to replace the system in our suburban at ~200,000 miles because we uses it all the time during the winter. It was less than $500. But I would rather pay that than lose a loved one to slippery roads. Matter of fact my wife rolled our 2000 GMC because she didn't turn it on. The road was dry and all of the sudden it turned to ice. We had a freak rain storm at below freezing temps on the pass she had to cross over to get home. I firmly believe if she had had it on she wouldn't have lost control.

Rolling a rig is scary. Glad she was OK.

Thanks. Yeah, I had just talked to her on the phone a bit before. She told me she was getting ready to come home. She was taking longer than usual she works in a ER so sometimes thing happen that causes her to be delayed. Next call I got was from her telling me she was in the ER getting looked at after the wreck. She apologized for the totaled truck. Hell, I could care less about the truck and still don't.

Auto 4 is the way to go.
