It sounds like when you bought it the previous owner or a shop that you had taken it to did what is called a "quick fix" in order to stop a noisy gearbox. I would imagine that the transmission is in dyer need of replacement or rebuilt.
Check your fluid level, low fluid and heat can cause it to stick. You may be able to work it back out of 1st after the lube ids topped off by driving it for a bit, and trying to move the shifter while engine is off.
one way... take off the shifter boot cover, then unbolt the shifter from the trans and pour directly in If you look on the passenger side of the trans there is a big bolt ya can take out to fill
A 1997 Jeep Wrangler TJ manual transmission engine can be filled with 6 quarts of fluid. Its cooling system, on the other hand, can be filled with 11 quarts fluid.
your brake fluid and your clutch fluid are in the same resavoir witch is just your master resavior and is located looking at the engine the right side toward the firewall
Bad u joint Transfer case was out of fluid,
NO no, you will ruine trans.
A 1991 Jeep Wrangler uses DOT 3 brake fluid.
no
If the shifter will not move you have a mechanical or electric issued with the shifter. If the shifter does move you may have low fluid or a failed transmission.
Warm up your engine since transmission fluid expands when hot. Set the parking brake on a level surface and put the shifter in neutral. Then pull the trans dip stick with the engine running, the same as checking your oil.
Dot 3 brake fluid
Just unscrew the cap and pour it in, it is on the drivers side engine compartment, high up on the firewall.
