1959 Dodge Coronet OD Trans

[48oldwood]

Well I found one. It has a small piece of wiring harness with a button. and its connected to a relay. It was shipped in 2 pieces and has everything with it. Give me some feedback on these #'s. Should I rebuild it while I have it out. It was pulled out of a running car 45 yrs ago. It came out of a '59 Plymouth wagon. My clutch is starting to slip under a load so It time to do a swap.

If you are good at assembling one of these then take it apart and see if it's worth fixing.  If not, clean it up fill it with oil and run it....Btw, what was the source for this trans?

A friend found it on a web site in ND.

Fits 57 to 61  but not the 40 to 56 where the R10 has proven popular.  The internals so far as I know are the same.

I have one here as you know, so congratulations on finding one closer to home.

You off a cpl of years on application. '59 was the last year for the flathead being used in passenger cars. It was almost in Canada. North Dakota is cold and a long way from Arkansas. It was sent in 2 pieces on Fed Ex for $210.

You are right about ND being cold and almost in Canada.  The freight rate interests me since cross border shipping has further expenses. To compound my shipping woes I am also on an island so most of the time I don't get involved.

Indeed the flathead was last used in 59, at least in the passenger car but I was told this  transmission  carried through..... no proof though and the only 61 left around here iv a V8 automatic.

From what I understand, the R10's are the ones to get. It's basically a three speed with a planetary OD behind it, engaged by a solenoid.

Things to consider are bolt pattern, input shaft length, spline count, and linkage. If you already have a three speed in your car, that might be a head start.

The guy who's an authority on these trannys is George Asche - his phone number is on here somewhere if you search. He rebuilds these regularly. There are also some threads from several years back discussing these that I recall.

Good luck!

After cleaning it I found these welded areas. It looks like these were reattached. Both of the double ears on the end of the tail shaft are heavily welded and 1 ear up a couple of inches appears to have been reattached. I don''t know if they were broken off completely or what. If the insides work correctly I guess it will be fine.

What does this transmission look like from the other side?  It sure resembles a OD that I got out of a 1958 Dodge 1/2 Ton Truck....
