Honestly, I'm not looking to completely rebuild the steering column. It's an old DOT truck, but I would like to keep it as it only has 55,000 miles. It's possible the ignition key cylinder housing was damaged when I drilled out the old cylinder although I don't know for sure. I didn't see any damage when I removed the cylinder although the lock pin on the bottom does not seem to be functioning properly now - it looks like it's stuck in the "up" position. If I could just find out why the shift lever is now locked in park and get the gear shift working, I would be happy to keep using the ignition actuator to start the truck.
From what I've read, two things need to happen for the shifter to move - foot on brake, and ignition to "on" position (in this case the actuator). Since the brake lights work properly, I'm assuming the brake light switch is working properly. I read a forum which said to make sure there were no blown fuses (like say, the air bag fuse) and said the truck could have a blown fuse and gone into "safety mode" (whatever that means). The other thing is the new key cylinder - even though it's not connected to anything, the key buzzes when it is inserted with the door open. I wonder if it might be causing some kind of shift interlock to engage. I will try to remove the cylinder to see if it has any effect. I will also check the fuses.
One other thing, on the steering column, there is a slot with a Teflon slider where the ignition actuator pin fits into. This slider (as I recall, before putting the new ignition cylinder in) would move freely back and forth (as it should, I assume - it's the mechanism the key cylinder uses to move the actuator pin). Now - the slider won't budge.
I removed the "shift interlock" solenoid and pawl on top of the steering column, but to no effect. I've seen conflicting descriptions of this part online, calling it the "shift interlock" and another that describes it as the "neutral safety switch". Can you identify it properly? I will attach a photo.
One last question - can you tell me if there is some other interlock (other than the one I removed) than this one that would lock the shifter into park? Is there one in the transmission? Or is it somewhere else on the steering column?
