3 speed saginaw with overdrive

[frost66gmc]

I found a 3 speed Saginaw with overdrive on eBay, but I don't have enough money to bid any higher. Maybe someone else is looking for one and has the money. The link is below.

Only 4 1/2 hours left.

I saw that one too...the guys in Canada but will ship out of Buffalo ...are they really worth that?

[frost66gmc]

I have never owned one, but they are rare. I have seen some totally rebuilt 3 speed with overdrive going for $1200 to $1300. My main interest in it is the overdrive and whether it will increase my cruising speed with lowering myc rpms. I want to get my truck up 60 mph crusing speed without the rpms excessively high. But the 3 speed manual transmission with overdrive are hard to come by. I currently have a 3 speed without overdrive, they are not as rare but mine does have sychcronized 1st and reverse gear. My next step is to change the gears in my rear end to see if I can get to my ideal cruising speed. This will be less expensive.

3:73 rearend with the overdrive. about 2600 rpm 70 to 75 mph

That's sounds awesome. I just don't have the money right now.I have a pick of gears on the one on eBay. I''ll try to post it here.

see attached photo

[frost66gmc]

Yeah I told the guy I needed to at lease see the gears with the cover off before I would bid on the transmission.

[frost66gmc]

Yeah, I would think it would be a great deal if the overdrive works, but that's a chance you have to take with ebay........

I am pretty sure that is what is behind the 292 in the parts truck I picked up. I was a column shift, can you make them a floor shift?

You will have to cut a hole in the floor, just go ahead and sell it to me lol

[frost66gmc]

Dad64, is the year and model of your parts truck, so I can keep an eye open for it. Thanks

[Dads64]

My parts truck is a '66 C10 long bed fleet side. I will put some pics of the trans up when I get the cab off the frame.

Thanks Dad 64, that would be a great help. I just want to make sure it has the overdrive. There should be a cable labeled overdrive in the cab that you pull to engage the overdrive. Thanks again.

[Dads64]

There was, I have actually taken the bracket and cable out of the cab as I am pulling the cab. I didn't even know it had the overdrive when I bought it, it was a surprise when I started tearing it down.

I see this post is a bit old but I just installed an OD in my truck today. I have two others sitting in my garage. Getting the drive shaft shortened this week also. This Trans is 5" longer then my stock one.

[studeclunker]

That transmission looks a lot like the Borg Warner in my Studebakers. If it's as efficent as the BW unit, this truck would get over twenty MPG. My Stationwagon with a V8 gets over twenty-five on the freeway. On one trip I got twenty-nine.

[andyh1956]

You can take that O/D unit & use it on the Saganaw four speeds to build a 4 spd o/d trans.

[rvrfoot]

Good info to know.

[Chevy Fleetside]

Was cruising on the freeway today at 75MPH. Felt the same as 60 without overdrive. I love it as I knew I would.

[andyh1956]

O/D is a Gift From The Gods Man!

[retrax]

Anyone around here use a Gear Vendors under/overdrive?

[jayoldschool]

No one here can afford it. lol

[Chevy Fleetside]

Got the cable hooked up today. Now I can have compression braking.

Which cable is that? I bought an O/D trans off ebay and have not installed it yet - hoping this winter. Did your trans have the harness or did you have to make it? Where / how did you mount your kick down switch? any info would be dynamite.

Is this a manual overdrive trans that you bought? Mine is still 3 on the tree. I just wired switch to the solenoid and activate it that way. The cable is attached to the rear lever so you can engage OD. So I have to push the cable in and pull the switch. If you look at the picture I posted you can see the cable on the bottom of the trans. I can take more pictures if you think they will help.
