Gear selector stiff...

I've been up under the car and the linkage isn't binding, but it's still hard to move the shifter, the motor was pulled but the tranny stayed put so I don't know what the issue is and the car hasn't been moved since. Any ideas?

Anyone? The shifter will go into the park location but you can't feel it actually move into park (I'm referring to the shifter itself, not the tranny shifting).

Bump, it doesn't feel like the shifter moves into any gears and just stays in neutral...

What's puzzling is how the shifter seemed to have worked fine before the engine swap, but suddenly afterward it's not working correctly. Are you positive that you felt BOTH of the detentes catch when the torque converter was installed? AOD converters have two stops on the input shaft, not just one. You push in the converter, it will stop, then you rotate it slightly and it will push in and stop again. Both of those stops MUST be done or else the converter isn't going to engage. That could also lead to a permanent "parked" position. If you're positive that the converter is okay, then read on.

First thing I would suggest is to get the car up in the air (preferably with all 4 tires off the ground for safety), and get a helper, and have him/her get in the car and put it through the gears while you're underneath watching on the driver's side of the transmission. You can do this with the car not running (good ol' 1980's safety standards!). The shift lever on the AOD casing should show a distinct movement with each gear. If not, then it's likely that the shifter cable needs adjusted. If you've already done this and it looks good underneath, the problem just might be something with the shifter itself, inside the car.

I recommend first checking the white plastic bumpy shifter rod ("gerbil balls" LMAO) that's inside the shifter lever. To get to it, you'll have to take the shifter handle off--push the button in and pull upwards at the same time. Directly underneath is the bumpy rod. Remove it from the lever (it's greasy, be careful) and make sure it's intact and didn't break...if it did, that's your problem.

If that doesn't solve your problem you will have to look at guts of the floor shifter mechanism itself. Remove the cover panel from the console, then the 4 screws from the AOD selector indicator cover (IIRC they're like a 5mm). Remove the AOD selector indicator cover and you'll see the little metal spring-loaded tang that sticks out of the shifter lever. That tang goes into a stepped metal gate on the base of the shifter. When you push down on the button on the handle, the bumpy rod inside the lever pushes down on the spring and lets it float between the stops. Release the button and the tang will hit a stop. So look for a broken spring on the tang, or a bent/missing tang, something along those lines. Even a too-loose or too-tight shifter lever will make the tang not engage correctly into the gate. You can tighten/loosen that up from underneath the car (remove the rubber plug on the passenger side of the shifter to access the nut; I think it's a 17mm or 18mm, and I don't think a deep-well socket works too well, I always end up using a shorter socket with an extension).

I've got my fingers crossed that it's just the bumpy rod...let us know...
