Behind glove box
Yes I just did that to mine, and it works great. No problems.
I have a 1989 Dodge B250...it has overdrive
You probably mean Overdrive solenoid, on the transmission left side Hope it's help
Piston rings and/or (probably and) cylinder walls are damaged. Rebuild the engine.
Try overdrive relay, you can buy them anywhere, replace old one, it is very easy.. I had to replace one on my 88 740. Give it a shot before you let someone work on it.

Overdrive should be ran by electrical ,so check your fuses . If that's not it check wiring that runs to transmission.You will have to get under the vehicle . There is an electrical switch that shifts the trans into overdrive , that is your next step . If you have a owners manual in the glove box it should tell you which fuse runs the overdrive circuit .Hope this helps . Rick
There is no separate switch for the overdrive, simply put the gear selector in the overdrive position. It looks like a D inside a square. Not all Chevy Celebrities have the overdrive feature, it was an extra cost option.
