SOURCE: 2000 jeep wrangler are sythetic lubes used in axils and trans
Hello grega1967, your Jeep Wrangler came from the factory with gear oil in the axles and manual transmission, but the transfer case uses transmission fluid. It is a NP231 and your axles are Dana 30 in the front and Dana 35 in the rear. They should have a 4.10 gear ratio due to you having a 2.5 liter 4 cylinder.
I hope this helps,

synchronizers are going bad a used trans would be cheaper than a rebuild due to the labor involved

Manual Transmission
The level of lubricant in the transmission should be maintained at the
filler hole on all manual transmissions. This hole is on the right
side. When you check the level in the transmission, make sure that the
vehicle is level so that you get a true reading. When you remove the
filler plug, lubricant should run out of the hole. Replace the plug
quickly for a minimum loss of lubricant. If lubricant does not run out
of the hole when the plug is removed, lubricant should be added until
it does. Replace the plug as soon as the lubricant reaches the level of
the hole.

DRAIN AND REFILL
Remove the drain
plug which is at the bottom of the transmission. Allow all the
lubricant to run out before replacing the plug. Replace the case with
the correct viscosity oil. All manual transmissions use SAE 75W-90 API
quality Grade GL-5 gear lubricant. Tighten the fill hole plug to 27 ft.
lbs. (37 Nm).
I hope help you with this (rermember rated this help) Good luck.
