Positrack rear differential controls great on wet surfaces.
2001 GMC Jimmy SLE
The only major problem I have had with this vehicle was a cooling fluid leak at the gasket between the engine head and the intake manifold. This was caused from two dissimilar metals I.e., aluminum on the new ' vtec ' intake manifold and a steel engine head. This problem usually occurs around 150k miles, mine occurred around 250k miles, which I was able to repair myself, no problems since then except for a water pump and an alternator. Vehicle could get better gasoline Mileage, presently getting @ 25 mi/gallon.
The vehicle is roomy enough for me and my dog when I go fishing.
Handles well on slick roads due to positrack rear differential. Presently has 268k miles and doesn't leak or burn a drop of oil.
I didn't know American vehicles last that long!
