SOURCE: 1998 jetta auto transmission is
I had the same problem. The transmission would not upshift into 3rd or 4th and 2nd seemed to rev on forever. I replaced the ignition and coil wires as well as the distributor cap and rotor and that fixed the problem. There was obviously some defect in the wires and/or cap/rotor. Although i am not a mechanic, I would say that since the transmission is electronically controlled, due to the defect in the above parts, the voltages going to the cylinders and thus the rev voltage limit load was not being reached or seen by the computer and so was not allowing the upshift. Since this was an ignition problem, I would check the coil as well.

Its located inside the trans and need to open the drain plug on the transmission oil pan with a socket and drain the oil into a drain pan, then need to remove the bolts that secure the transmission oil pan to the transmission.
Now could you to remove the bolt that holds the transmission dipstick bracket to the bell housing with a socket. You can locate the bolt from the engine compartment. Place a scraper between the transmission pan and the bottom of the transmission and break the seal loose so you can remove the pan.
Remove the defective solenoid by removing the bolt that secures the solenoid to the harness. Three solenoids control the shifting on the Jeep. All have white and yellow wiring harnesses connected to them. The solenoid to the left (towards the Cherokee's engine) controls shifting "overdrive." The solenoid in the middle controls shifts between second and third gear. The third solenoid, closest to the rear of the Cherokee, controls shifts between first and second and between third and fourth. If you know which gear your transmission is stuck in, replace the solenoid that corresponds with that gear. If you are not sure, remove all three.
