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.

Sincerely, Woody Cofield.

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.

I have a 1991 Geo Tracker. I have found it very hard to find parts for the rear differential. I have 6 gears and 4 of them are cracked. If there is anyone out there that can help me out, it would be great. I would really like to have a rear differential locker system.

In response to trailer hitch wiring... you shouldn't have to splice the pigtail into your wiring for the 1991 tracker. Open the little side panel on the driver's side by reaching in through where you replace rear light bulbs on the driver's side. If you reach up in the back of the wheel well, you will find there is a plug pre wired into the wiring harness, it may be taped back against the harness, but the pigtail plug should fit that plug. It took a little wiggling, but I found it was on my 1991 tracker.
