Where is the overdrive relay located? - 1990 Mitsubishi Mighty Max

On the inside of the transmission pan it's at the front at the pump

It is not an overdrive transmission. It is a 4 speed automatic. It has no overdrive relay.

let me know if you want me to help you wire it

bad relay switch

Relay located behind fuse box.

Hi, the relay for the overdrive is located in the center of the dash to the left of the glove box way up under the dash. It's a long reach so use a flashlight. Enjoy!

You can find it behind the fuse box. To access the relays. Remove the plastic cover on the cigarette lighter socket, remove the screw, and remove the ash tray to gain access to the fuses and panel whit the lighter socket. The relay is marked number 123 or 136, found all the way to the right second row.

Hey try this. Buy an over-drive bypass plate from IPD (www.ipdusa.com). I had the same problem with my 91 Volvo 940 Turbo. My overdrive solenoid went out, but that would have been $160 to replace. The bypass plate was only $40 and it fixed my problem.

Overdrive relay usually fixes the problem. With the engine idling quietly, press the OD switch on the shift lever. Do you hear a click? If not, it is probably the relay. Located behind the glove box, passenger side. toward the center console. Pick up a used one on Ebay ( about $10 bucks) and swap it out. Cured my problem right away. Be sure you change the correct relay because Volvo hides several back there. I would buy the spare, then match it with the one now installed. If not the relay, you will need a new solenoid in the transmission. About $200 installed.
