Had transmission put in 4 months ago.
I disconnted the shift cable at transmission and could not get shift lever to move.

There is a park lock mechanism on the shifter that keeps it from coming out of park until the brake is pushed. I would check into this, maybe there is a problem with the brake light switch on the brake pedal or something. A quick check could be have someone watch your brake lights for you, the lights should come on within a very short push on the brake pedal.

With the cable disconnected, can you still move the selector on the gearbox?
That quickly isolates the problem to being with in the gear box, or with the gear stick and assembly.


Normally the lock out is in the gear stick, and it can usually be over ridden manually encase the engine can't be started.

I can move shfter if I take off cable. Looking at wires right now.Something I didn't think of before had remote start install about year ago.If I don't find anything with wires don't know what to check.

When you look at the inside of the shifter cycle the knob button in and out. Watch for something around the shift lever that is preventing the button from being pushed all the way in so you can shift from park. There will be some kind of electrical park lock mechanism in there, a solenoid of some sort.

Also, as was previously posted, take the shift cable off the tranny and make sure you can shift it by hand. If you can't the problem is in the transmission and not the shifter.

While you have the cable disconnected at the tranny, try operating the shifter. If the shifter will work with the cable unhooked, the problem isn't in the shifter.

It working again, but I still check things. Wires all look ok. Can you change Solinoid beside shifter or lock it out. There is a small button outside the solniod. Can not find a wiring diagram for wires running from shiftter.

Thanks

one thing that i accidentally found is that if you pull the fuse for the air bag, the transmission shift lock release will not work. replacing the fuse solved that issue.
