More detailed observations.
Transmission is a THM200c 3-speed
Hooked up my OTC 4000 Monitor to confirm a few things.
1) Shift Selector at Column will not stay in Park.
2) Shift Selector at Column doesn't find Neutral.
Driveability:
-When setting Column Selector to Reverse transmission responds (car goes into that gear)
-When setting Column Selector to "D" or "2" I just get a whirring noise.
-When setting Column Selector to "1" transmission responds (car will drive forward).
Diagnostics:
-Disconnected the Column Shift Linkage from the Transmission Linkage as described in the FSM.
-Moved lever at transmission clockwise to Park, then counterclockwise through all gears. No play in the lever and get solid clicks at each point and lever stays put.
-Put the ignition to on position and tried moving the Shifter at the column through the gear selections. Still will not stay in Park, finds Reverse but nothing but "play" between R and 2. That is no solid clicks or stops.
-Tried the adjustment procedure according to the FSM but it was sorta useless and the column shifter can't find the "stops" for "N".
At this point I'm gonna replace the entire linkage and bushings. But I am wondering if there is anything at the Column I could be missing?
I'm not sure if it's the transmission as it doesn't seem the transmission is getting the input it needs to know where the Shift Selector is.
Thanks to ne1 who is willing to offer up suggestions and or help.
