Check your shifter cable. Be sure the it is properly conncected at the tranny. Also if parked on a hill and the emergency brake was not set, it may need a little bit of force to pull the level out of park.
Remember the shifter will not move unless the brake is applied.
If you are no longer able to shift, then it's possible the linkage is broken. If this is a periodic problem, you may need to adjust the linkage or shift cable so that everything is prooerly lined up
SEE OBD II drive cycle
can not get 4 wheel drive to shift in 1998 Tahoe
First a question. Were you stepping on the brake when you tried to shift it out of park?
It is rear wheel drive, until you shift it into 4 wheel drive.
Bad Ignition lock cylinder , Bad shift interlock solenoid, burr on the key.
Push the 4wd button.
If it's in limp-in mode you need to take it to a transmission shop and have it diagnosed.
It's the brake switch. It tells your break lights to come on.
if its a manual transmission its your pressure plate if its an automatic it could be the disc attached to your flywheel
try putting vehicle in neutral, then unlock hubs.then put vehicle out of 4 wheel drive
I don't know how to fix it perse, but we ran into the problem in my roommate's 98 SL2 where it was sticking and locking the key in the ignition. The problem was the actual mechanism where the shift lock connects to the gear shift was stuck or malaligned or something, if you pull out the cupholder and wiggle on it it seems to unstick it. I'm thinking a good cleaning should hopefully fix it permanently. I'm not even sure where to buy a replacement interlock.
