Might be a problem with the brake/transmission interlock switch
A 1998 Jeep does not have a shift modulator.
To adjust the shift linkage on a 2004 Jeep, first, ensure the vehicle is in park and the engine is off. Locate the shift linkage adjustment point, typically found near the transmission. Loosen the adjustment nuts, then move the shift lever through its range of motion to ensure it aligns properly with the transmission. Once aligned, tighten the nuts securely and test the shifter to confirm smooth operation.
no
Stick shift.
Into Park or out of Park?
If you do not have your car turned on the vehicle will not shift out of park. You also have to have your foot of your brake.
The shift solenoid is inside the transmission on the valve body.
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.
If your Mercedes won't shift out of park, you might have an issue with the brake sensor or the brake itself. The brake must be fully depressed in order to shift from park to drive or reverse.
