Borg Warner R-10-R-11 Overdrive Solenoid 12 Volts
This is the same solenoid used by all eleven of the car companies that offered the Borg Warner electric overdrive as an option from the late 1930's through the early 1960's. This solenoid will fit standard Borg Warner overdrive applications with a shaft length of 1", measured from the tip of the shaft to the edge of the alignment flange. (lay your ruler on top of the shaft and measure from the ball end to the edge of the alignment casting). The alignment casting is the round part in the center of the large flange with the 2 mounting holes.
All standard overdrive-solenoids will measure 1". However Wagons, Convertibles and Lincoln's will measure 1.5 inches and a few odd applications will measure 1.25 inches or longer.
This solenoid fits the STANDARD 1" applications. Please check you shaft length before ordering. MEASURE SHAFT LENGTH BEFORE ORDERING TO MAKE SURE YOURS IS indeed 1 INCH IN LENGTH.

Solenoid wiring terminals with the solenoid in hand and the shaft facing out in front of you, the right hand terminal is number four and connects to the relay. The left hand terminal connects to the kick down switch. A small amount of solenoids had a third wire that was a ground if yours is one of those check your shop manual and it will confirm where the third wire goes. Most solenoids had screw in terminals, a few had internal connections with wires coming out of the solenoid. Wiring connections for both are the same.
When changing the solenoid we recommend always changing the seal in the transmission. This will prevent oil from entering into your new solenoid.
There is a seal in the solenoid itself that can;t be changed in the field. The seal that you can change is in the transmission where the shaft goes through.

Works perfect, was more difficult to install then the stock one but it went in eventually! (Once it was in I couldn’t twist it and I was afraid I was going to damage the shaft if I used some channel locks)
hard to find part before we found you. customer is happy and part works great. appreciate the followup thanks
well built overdrive very solid, easy install, I do suggest they if you order this to also order the seal to prevent oil leaks. thank you,
Thank to you for your quick service. I installed it yesterday afternoon and evening... took it for a drive last night and it checked out! This noon, we drove 50 miles to Lorton, Ne for a beer and burger.
