4 speed tranny

[daimlerchryslerman]

Hi guys,

My latest adventure is a 1/2 ton 1950 dodge.

I am currently having the engine rebuilt.While i'm at it i was wondering about the tranny.

It is a 4 speed model but I think it has no syncro.

Is this normal.

I can see a 4 speed listed in my Canadian parts book but cannot find one listed for the 1/2 ton in the on line parts book.

Any clarification out there ? I like to look up original #s for bearings and seals and then cross them to jobber #s but I have not found a 1/2 ton 4 speed in the book yet

Cheers ! Ray Morris

I have a 4 speed trans in my '53' B-4-B. Found out from an old dodge dealer years ago it is a New Process Trans. No syncro between 1st and 2nd or 2nd and 3rd. but one between 3rd and 4th. Can only downshift from 4th to 3rd. Upshifting has never been a problem.

I read recently on another forum that 4-speed synchro boxes have the drain plug at an angle to the floor, while crash boxes have the drain plug parallel with the floor - two differenr vendors. Both were used. Instant visual recognirtion as it were . . .

Hope it's true - can't speak from personal experience. Please let me know if you find out more.

Thanks

Actually it's the other way around. Parallel to floor is synchro. Angled down is crash box.

Thanks for the info guys.

I do have a syncro type in my 2 ton and it seems that the 1/2 ton is non syncro.

My concern is that i could not look up part #s for the non syncro in the parts listing as listd on this sight.

I wonder if any one has the U.S. parts book to see what the original part # for the 50 1/2 ton 4 speed is so I can look bearings etc up in my Canadian parts book if the assy is the same.
