My jeep wrangler keeps loking in gears
Jeep Wrangler only,
check your shifter bushings, next would be inside the trans at the shift collar.
if it is an auto, you will have slippage even though the fluid has been replaced and filter changed, it will have a hard time shifting and may even be stuck in one gear. For a manual, you will have a very difficult time shifting ( clutch is ok ) downshifting will be almost impossible and you may get permanently stuck in one gear.

If a 2000 Jeep Wrangler suddenly loses power in 5th gear, it might be a problem with the speed sensor on the transmission. This sensor regulates when the Jeep will shift or should shift.
Could be 3.07, 3.55, or 3.73
