98 Jeep Wrangler won't go above 30mph

I have a 98 Jeep Wrangler Sport and yesterday it started going very slow. It won't go faster than 30mph and the RPM goes up to 3500. This morning when I got to work, it wouldn't move when I put it in reverse. Any ideas? Is this a transmission problem? Any help is appreciated.

Have you noticed any large quantities of oil on the engine or on your parking space?

No leaks of any kind.

It's an automatic, 6cylinder. I have an appointment tomorrow, but I'm just hoping I can actually get it to move and get home tonight.

Does the rig have a tranny cooler installed?

Yes, all TJs with factory installed automatics have transmission coolers.

I was going to suggest checking those lines for leaks. Just had this happen to my Kia where it got a crack in the line from the cooler. As more ATF leaked out, the symptoms he noted were the exact same that happened to me trying to limp it to a place to pull off the road. Just a thought.

Please forgive my ignorance, but what does a tranny cooler do? Is this a minor repair or will I need a whole new transmission? This is the only Jeep I've owned and this problem is new to me.

Have you checked the tranny fluid level? No fluid, no movement.

Just got an oil change a few weeks ago. They were supposed to top off the fluids.

Odds are very good they never bothered to check the ATF level in your transmission.

It will take you two minutes to check it on your own... warm up the engine & transmission, make sure the engine is running for this. Shift through all the gears and after setting the parking brake, shift into Neutral. Neutral, not Park. With the engine running, check the transmission dipstick located on the passenger-side near the firewall for proper ATF level per the markings on the stick. Make sure the ATF is a pinkish-reddish red, is clear, and is not burnt smelling.

Thanks for all the advice. I will check the fluid levels and keep my fingers crossed
