RedHeartbeat: I have to remove the shift lever from the tranny so I can beef up the ball stud that attaches to the shift cable.
You may not have ran into this when you removed yours, but on mine the nut
as well as the threaded stud is rusty. I'm afraid if I wrench on it too much I'll break something in the tranny - and I can't hit it with heat because of the
switch behind it.
Any thoughts?
Thanks.

leave it on the shaft. Drop the pan and remove the nut that holds the shaft to the shift mechinism inside the transmission. Unbolt the shift selector and unplug the harness and pull the whole assembly out at once.
