Hey I didn't malign the part. Looks like it should be good for another 5 years. At least the bottom part, it looks hardly used. I figure a bit of creative adjustment, and you have it made.

I won't have you guys making fun of my old crap.

Don't worry Joe the brand new one I put in my truck may look that bad now too after I drove about 2 miles with the brake on!

Joe the fuse just sits in a holder. The wire for it comes off the bottom and is still somewhat there in your picture. You can kinda see it on the firewall of my 51

Joe if you do look at 40s and earlier mopar cars and trucks for the headlight switch. I bet they are close. Might even try headlight switches or under hood of other cars. Lots of fords and independant makers had OD too.

Thanks to suntennis for the test he recommended. I have determined that my overdive relay works. Clicked when I applied power to it and got continuity between the "Batt" and "Sol" terminals. Cleaning it up now and trying to figure out where I will install it.

If you do not have it you will need a kickdown switch and mounting bracket. If you have the switch, you can also test it. Other than George Osche, another place for overdrive parts is fifthaveinternetgarage.com .

Joe,

You may have already done this but I tested my governor by chucking it up to my drill press and then checked for continuity with the drill spinning. I would think you could do the same with a hand drill.

Interesting idea, Jim. How did you make the connection between the governor and the drill? I pulled the cover off it, by the way, but didn't want to go any further. I cleaned the contacts and made sure the spring and weights were free but that was it. It looks sludge-free and in good shape.

There is a drive shaft that connects to the governor that is driven by the drive gear in the O/D. It just pulls out once the governor is removed. I just chucked the drive shaft in the drill and clamped the governor in a vise.

Thanks, Jim. I might just leave it be and not mess with it unless I start having trouble. You've heard of Pandora's Box letting evil spirits out? I've come to the conclusion that opening up an overdrive transmission works like that in reverse. It lets evil spirits IN!

Joe,

You should take comfort. All the evil spirits are unfortunately residing in my O/D so they should have no interest in yours.

Just wondering if I should take the speedometer cable pinion gear out of my old transmission and install it in place of the one that is currently in my overdrive transmission. I read something a while ago that said that when switching transmissions like this, you should do this, since the rear end ratio of the car the new transmission came from might not be the same as yours. Any opinions on this? For what it's worth, my car is a 49 and the overdrive came out of a '52. I believe the gear ratio was the same for both models but I'm not positive.

Joe,

I would take them both out and count the teeth. It is my understanding that the O/D equipped cars usually had lower rear-end gearing. You would want to keep the speedometer drive gear that matches your rear-end.
