Geo Tracker help ?? Tracker owners?

Here are the two engines.

8 valve TBI


16 valve MPFI the red arrows point out the "16 valve" logos.


You must have a very economical route because the 20*f morning commute nets me about 26mpg. Over a tank I get 28-29mpg.

I guess if you do not plan to tow you could switch out the rear end gears for a higher ratio, but if its 4wd, you got to do both.

Ive toyed with that idea since it runs high rpms at highway speeds. Of course it would loose its towing ability, but I thought I would shift to 4wl for that.

I know it says niot to use 4wd on pavement, but my tacoma said its max towing capacity was in 4wd.

Geo trackers weren't meant to tow. Doesn't mean people don't but since these vehicles weigh a little over 2000 lbs towing would be iffy...

There have been people that swap out the 5 speed diffs for the diffs found in the autos in order to get the revs down but quickly realized that 5th gear became almost useless. These little engines just don't have the torque to be playing with gears like that.

Also you aren't suppose to use 4WD on pavement for a reason. Binding up the driveline is the fastest way to break something. Yes it is possible to drive on pavement in 4WD but Use it only at low speeds...you have to be extremely careful and not to turn the wheel much. Also when you turn the wheel you need to let the driveline tell you how much you can.. Feel the wheel go back and forth by itself you will know what I mean. Forcing it will bind it up. If you have to make a sharp turn you need to pop it back in to 2WD. Before I had my NP242 T case with 4WD full time in my Jeep I used to have the NP231 and used 4WD part time during nasty winter days since the added traction was necessary... I did the above and luckily didn't break anything.

As is with the larger tires 5th gear acts more like an over drive for 45-55 mph. Otherwise I find I need to go to 4th when the going get tough.

The idea in the stock configuration of tires was to switch out the ring and diff gears in the car for a higher ratio, then when you wanted lower ratios shift to 4wd low.

I havent driven the kick that much. My tacoma I had I did 10 thousand miles. When it was raining or slick out I shifted to 4wd with no problems, then back to 2wd in parking lots.
