You'll have to remove your console first. Once you've done this, you should see a cable with a couple of nuts on it running along the console. Loosen these nuts and then pull the cable casing forward until the inner cable has no slack in it and then tighten both nuts. Just make sure to check that it's working properly before you put it all back together. If you have it adjusted right, you should be able to turn the key from accessory to the lock position and pull the key out. If not, you need to work on that cable adjustment some more. This is a safety feature and there's no way to override it.
Thils is a typical problem in the geo transmission. There is a check valve in the shift body of the transmission. It is easily fixed and costs next to nothing. If you haven't fixed it by now contact me and I'll give you the information. Mr Geo Metro leehduncan@verizon.net
The problem might be the mechanism from the brake when you step on it that won't allow it to shift.
If your Blazer won't go into park the problem could be with the shift linkage. There could be a problem with the cable, but the shift linkage is most likely responsible.
Sometimes when used to driving manual transmissions, we forget to press the brake pedal to release the safety so we can shift the automatic into gear. It will not shift out of park unless you do this.
Align the shift indicator orreplace it. Your problem is strictly column mechanical.
Might be a problem with the brake/transmission interlock switch
If your shifter is on the steering column, the problem is probably under the dashboard on the steering column. It is an easy fix. remove the panel under the steering column, and spray silicon lubricant on the shift lever that extends out of the column that the shift cable is attached to. 9 times out of 10 this will be the problem. Or, you could follow the other suggestions or have your transmission replaced. but at some point, you will need to lubricate this linkage to fix the problem.
Put your foot on the brake.
Park metro station was created in 1969.
the shift interlock cable,sounds like the problem
shifter control cable is probably come off @ linkage
Can be a linkage problem check linkage that goes form transmission to shift the vehicle
