Gear stripped on speedo plug in tranny and gear in tranny Can this be replaced?

Yes.

Can the tailend of the tranny be removed to replace the gear? I can't believe it's plastic, the gear that is. I've never ran into this problem before on any vehicle. I used synthetic gear oil when I replaced the clutch the last time, thought it might help mpg a little bit. That could be the culprit.

If you have a 2wd, then the gear is located in the tail end of the tranny.  If you have a 4wd, then it is located in the tail end of the transfer case.
For the tcase, you need to pull the rear half of the tcase off, to get to the speedo gear.
For the tranny, you need to pull the tailshaft housing off and the speedo gear should be right there.  Just remove the c-clip to get the gear off.
Synthetic gear oil will not affect the speedo gears.  Maybe your speedo cable is "sticking" a little bit inside the cable housing and causing the cable to turn hard and that is what stripped the gear (although generally it just breaks the cable).
Did it strip/damage both gears?  I'd guess it probably did.
When you go to replace the gears, you need to make sure you get the same colored ones as your old ones, because there are a few different tooth choices, that varies depending on the color.
The only trackick speedo gears that I have ran across that have been metal, are the ones out of the 89 sidekicks that have a 1.3 engine and a 5 speed manual tranny and 5.62 axle gears.  Of course you don't want to use those in yours, because the tooth count is different from yours and your speedo won't read correctly.

Thanks for the info. Sorry I meant the transfer case. I usually do all repairs on my vehicles. I guess the real question is where is the best place to find these parts? I'll try to get some pics up of tracker soon , I've been slackin on that. It's the best vehicle I've ever owned, daily driver. Custom wheels, exhaust, calmini header, custom fab cold air intake, bushing lift, 30-9.5 tires, stereo etc. plus replacing everything under the sun new. whooo. four years worth. But I swear by them.

Dealer or online parts vendor is probably going to be your best bet, unless you can find some used ones from someone parting one out. 
Like I said, just get the same colored ones as your old ones, and the tooth count will be the same on the gears (note, that the driven gear and the drive gear are not going to necessarily be the same color...so be sure to check both colors).

Thanks again and thanks for the heads up on the color thing.

Dang!  I have the exact same problem with my 97 Kick.

Glad I have a spare transfer case!

Make sure that your odometer isn't working before you tear into things.  I have had a couple of bad speedometer's where the needle breaks, so the speedometer stops working but the odometer just keeps on chugging.

As long as it came from a rig that had the same tranny and axle gears as yours, then it should have the correct speedo gears in it.  If it didn't, then your speedo won't read right....but maybe that is better than not working at all.

yeah, unfortunately on my 96 it has speed sensor in the speedo, so the ecm does'nt read the speed right. Has a stumble at full throttle. I relaced the speedo already and cable, this is when I found the gears stripped. Yee Haw.
