I have a 96 grand cherokee that wont pull out in first gear

Hi,you need to jack car off the ground,and put selector in refirst and aply hand brake,undo the gear leaver from the gearbox then manualy put the gear selector in park position then ajust selector linkidge so that it will go back on without pulling the gear selector out fom its position,if it dose not pick up park now there must be something wrong with the gearbox.
hope this was some help.

Check the T.V. Cable linkage at the tranny end. Make sure the return spring is pulling the linkage back on its own. I fixxed a 96 and an 02 shifting at 3000+ by spraying this linkage and cable with WD40 and working it back and forth untill it moved all the way to the peddle up position by its self. Parts were rusty and sticking when turned past a point.

Yes it can be done as long as all the parts for 96 are used including the iring harness and computer and the exhaust system.

Need to adjust the selector cable

Also check brake switch adjustment, it is the interrupter.

CHECK FUEL REGULATOR ON FUEL INJECTOR RAIL,&ALSO FUEL PUMP, CHARLIE

My 1998 does this. It may be the cable from the Transmission Selector to the Steering Column. I have not yet "cured" this, but the work-around is:

When the key can't be removed, with engine still OFF, set Parking Brake, then pull Gear Selector Lever from PARK all the way back, then return it to PARK.

Your key should now come out slicker than deer guts.

Pretty Mickey Mouse, I know, but in this economy, I don't have $200 for the Jeep Stealer to adjust the cable.

check the fluid level in it

No, not with out a lot of work. Electronics are most likely different on the 2 also.

the simple fix might be the park interlock cable. this locks the shifter unless you press and hold the brake pedal while selecting gears. I've seen and replaced a few of these on several chrysler/dodge vehicles.
