Thanks Chris

Lets start again.
1. Overdrive On light started flashing. Auto trans shifting jerks with all shifts.
Switched out Neutral Safety Switch with a used one and it worked for a few days.
Problem has returned (with a new problem)
2. New Problem - constant beeping from rear drivers firewall. I have to pull "room" fuse to get it to stop vehicle is off.

1: Did you scan it to see which codes are stored? A flashing OD light means there are trans codes stored.

2: This beeping is it the warning chime in the car, the horn, or an aftermarket siren?

Customer: replied 7 months ago.
1. I don't have a code reader.
Is there a way to reset?
2. Constant beeping seems to be related to power doors. No aftermarket siren.

You can remove both battery cables, hold them together for one minute, then reconnect 30 minutes later to reset the computers. However this will not fix the problem. It will just hide it till the computer sees the issue again. Kind of like putting bubble gum in a hole in your boat, the leak is going to come back. The codes and issues will return with diag and repairs done.

The key in reminder switch at the ignition cylinder maybe sticking and telling the instrument cluster the key is always in the cylinder and causing the instrument cluster to signal the chime. Access this switch with the steering column covers removed and ohm test this switch with the key in and removed to see if the switch is opening with the key out. With the chime going off only one wire to this switch should be powered with the key out. See the diagram below.

I will try and get codes if it will help figure this out,.
Customer: replied 7 months ago.
beeping is steady two beeps per second
OD light & "slamming" into every shift (up and down) seems dangerous if roads are icy.

The codes would help

Customer: replied 7 months ago.
do I need a special type of code reader??

It can not be a cheap generic one. It needs to be sophisticated enough to have access to the transmission.
