Borg Warner Overdrive Lock Out

Hi All,
I installed a Borg Warner overdrive in my coupe. All that is left is to run the wires and the cable. Currently the lock out is pointed towards the back of the car. Please see the attached picture. My question is if the lock out is in that position am I now considered IN overdrive once the switch is flipped to ON for the solenoid? Or does the lock out need to be in the down position to be considered IN overdrive? I just want to make sure when I run the cable and I push the cable in that I am considered to be IN overdrive. And when i pull the cable out that I am considered OUT of overdrive.

Thanks,
Denny

If anybody needs to have their Borg Warner overdrive solenoid(s) rebuilt, then let us know as we have been rebuilding them for many years now. We take them apart, clean them, re-assemble and replace parts if necessary, test and then put in new seals and paint. Just need a Saturday to do the job.

Good price and fast service!

Thanks and be safe!

Generally they are always pulled out for lockout (lever on unit forward) and push all the way in for overdrive function. The cable would have to come in from the rear to be the other way around.
 
Thanks Rotorwrench. I was thinking the same answer you provided. But I needed someone to confirm it to ease my mind.

Okay,
You will know you have it engaged when you can free wheel . So with cable pushed in at least on my car if driving down the road you let off gas it will not slow down it will free wheel almost like being in neutral. So if going down the road and engaged by pushing cable in after going into third let off and let engine rpms come down energize the solenoid via toggle switch and will feel like transmission shifted now in overdrive , when want to disengage shut solenoid off. Also Never try and go in reverse with cable down(overdrive engaged ) you can lock it up due to the one way sprag in unit . But read both articles I posted in previous post both have a lot of useful information.
 
There was a fellow in Calif. named Bob Bell many years ago who built overdrives and included a lever connected to the shift tower shaft of the A ****** that would automatically lock out the OD when placed in reverse. Perhaps someone has his or other's diagrams how this was done. He also designed a kick down switch placed in the floor board.
 
I have worked with a gentleman name Jack Thomas who has installed approximately 75 Borg Warner O.D.s. He would purchase them from a man named Bob Green in Ohio. They would drill the back of the A ****** top into where the shift rail slid back, installed a rod and swivel bracket which when you put the trans in reverse the shift rail activated the swivel bracket which kicked O.D. out of overdrive. Works very well and is fool proof. I have replaced two damaged sun gears and cluster gears which were damaged when O.D. was in overdrive and cars was operated in reverse.

I would love to know more about this modification.

That's exactly what Bob Bell did with a 1/4" rod. This was in the 1980's and I forget how he sealed the ****** top hole.
