1991 Geo Tracker 4X4 from North America - Comments

Overall engine performance has been good, engine seals went bad around 133,354 miles but were an easy repair.

Some parts are very hard to come by - computer, air duct hose.

I found that during cold weather, if not warmed up for around 10 minutes, the transmission may not want to go causing wasting of gas, but during the summer, fuel mileage was around 160 miles to a full tank of fuel.

The best oil to use in the changes is Valvoline, it's the best amount to use and lasts the longest.

Keeping general service done will keep your Geo running at top shape for many years, but attempt to keep it washed as much as possible due to road salt and dirt eating away at the paint.

Tires are also good to keep into condition, the best bet would be Goodyear all season tires, they last the longest and wear down the best, should last at least a year and 1/2 if well maintained.

A full tank of fuel will last around to 140 miles or more, depending on how often you drive the vehicle.

Steven, I'm guessing you have an automatic tranny. If so, you probably have a leaking isolation valve inside the converter, so the engine has to fill up the converter when you start. Try running it in neutral, because the pump will then fill the converter while you warm up the engine.

You report 160 to 140 miles on an 11 gallon tank... that's horrible mileage for this car! You should be up around 200 to 260 miles on a tank with the automatic. Has anybody checked your O2 sensor?? If it goes bad, your mileage gets bad.

Thanks for the info guys. I too have a '91 Tracker 4X4 and the tranny, (when cold) will slip between 1st. & second.

After 30 to 60 seconds of driving it works great and is the smoothest tranny around.

I love this SUV and deliver the mail in it part-time.

Also one other thing. The manufacturer recommends 23 pounds of tire pressure. I tried 35, then 30 and what a stiff ride it had. Then, I tried the 23#'s and it rides MUCH BETTER. I guess they know what they're talking about.

Thankx again for the info. Woody.

I tried the (warming up the engine in neutral trick) to help with the vehicle not wanting to shift when cold and it helped a little.

I soon tired of having to let it warm up especially now that cooler temps are here.

I changed the transmission fluid and filter and added Castrol transmission fluid and a can of TransX, (it's a thin anti-slip trans. additive), and now the problem is GONE! It shifts perfect even when temps are below 30*. No more wasting gas waiting for the engine and tranny to warm up.

One note though, you must remove the 4 bolts on the front drive line and drop the shaft to remove the pan on the 4X4 models.

Hope this helps those who experience a transmission slip, it was probably just a dirty filter and the fluid couldn't get through.

I recently added a trailer hitch to my '91 Tracker.

I don't want to cut wires and splice into my tail lights to install the lighting pigtail for the trailer lights. I searched several auto part retailers and catalogs and cannot find a plug-in kit to add the pigtail.

Does anyone have any info. or ideas on how to install the wiring pigtail to a Tracker without cutting and testing the rear wiring?

Thank you & sincerely, Woody Cofield.
