Overdrive quit working

[53dodgekustom]

Hi, I put a R-10 overdrive trans in my 53 Dodge a few years back. I'm just running a toggle switch to the solenoid, I didn't bother with all the governor and carb stuff. It worked really nice. Flip the switch let off the gas...a nice clunk and you in overdrive. Worked perfect. Last July (08) I blew the Flatty and I just now got it running again. But now my overdrive won't work. When I just have the key turned forward and flip the switch I can hear the solenoid click on and off. But driving down the highway it won't kick in to od. And yes I have the cable in the right position. It freewheels just as it should. Anyone have any idea's? All I did was take the trans out and put it back in. Never touched it otherwise.

Could this simply be a short in the wiring, poor connections at switch or solenoid contacts.

Have you tried a testlight/meter to see if the switch works, or if you are getting juice in the circuit?

[53dodgekustom]

Yes it has power. I put a test light on it and it lit right up. Like I said you can hear the solenoid click in and out just as it should with the ignition is on. I need to start the car and have someone flip the switch while I'm underneath it to see if it's clicking like it should I guess.

I had mine originally wired like you with just a toggle switch and it worked fine for a while then just quit working. I bought a new switch, rewired it with a heavier wire, even got another solenoid. Nothing.

So, I wired it like Pete has his, per the factory wiring diagram minus the circuit which temporarily cuts power to the distributor and it has worked great ever since.

There is a pretty good trouble shooting section in the Borg Warner manual that you can download from the main P15-D24.com web site.

Is your generator working correctly? I have a friend who had the same overdrive problem when his generator failed. Once he repaired the generator the overdrive once again shifted as it should. Low voltage could be your problem.

Don,This would be the correct answer!!! My generator quit right before I blew the motor. I mounted up an alternator yesterday but haven't got it wired up yet. I just drove a few times to make sure the engine was running right and so I could do the first oil change. The battery is charged but yea since I don't have a charging system i'm sure its only putting out 10 or 11 volts. Hopefully I will get it wired up today and see if that works. Thanks!!!
