John32369 Posted September 1, 2017 Report Posted September 1, 2017 Would a R10J-1 overdrive fit a 48 Dodge truck transmission? Quote
medium_jon Posted September 1, 2017 Report Posted September 1, 2017 Which do you have @John32369, the overdrive or the truck? Quote
John32369 Posted September 1, 2017 Author Report Posted September 1, 2017 I found an overdrive mated to a transmission. From what little I've learned it would fit a 57-59 Plymouth or a Dodge truck. I know where I can get a transmission and motor for a 48 Dodge truck. I figured that would probably be a 230 motor. I would like to put a straight drive in my 48 Dodge business coupe with an overdrive. So I figured I would get it and see if I could make it work. I know it's not original but I figured I'd try it anyway. Quote
John32369 Posted September 1, 2017 Author Report Posted September 1, 2017 So I guess the answer would be the overdrive lol 1 Quote
pflaming Posted September 1, 2017 Report Posted September 1, 2017 It might be easier to put a car bell housing on the engine, install the car rear engine mount cross bar, then use a car transmission and overdrive. May be a crazy idea but . . . .? Quote
hkestes41 Posted September 1, 2017 Report Posted September 1, 2017 You want the entire transmission with the OD not just the OD. That and the proper bellhousing with the 230 should be a direct bolt in to your coupe. Wire up the solenoid/governor/kickdown switch and you should be good to go. 1 Quote
dpollo Posted September 1, 2017 Report Posted September 1, 2017 (edited) To install an R10 Overdrive in a light truck, you must have the complete unit with its three speed gearbox ( 52 to56). A 3/4 inch adapter plate must be made for the front of the trans and the column shift linkage must be significantly reworked. Also the driveshaft must be shortened. However US built trucks may differ from my Canadian model. Their transmissions were not all the same. In any case, I have found my installation to be very satisfactory. The most challenging aspect was to make the parking brake work. The R10 J as found in 57 to 59 cars has a rather long input shaft which makes it unsuitable for some applications. Dodge B4YA gives the best advice, above. Elsewhere on this forum is a thread discussing truck transmission choices. Edited September 1, 2017 by dpollo clarity Quote
John32369 Posted September 1, 2017 Author Report Posted September 1, 2017 I have the overdrive and transmission, Seems like it was out of a 57-59 Plymouth or Dodge truck Quote
dpollo Posted September 2, 2017 Report Posted September 2, 2017 Well then, you never know until you try. Quote
Dodgeb4ya Posted September 2, 2017 Report Posted September 2, 2017 I put one in a 52 B3B panel years ago. Drive shaft was shortened.. new end on it. Modified the shift linkage. New front bearing retainer and more ...I just don't remember. Drove it everywhere... including canada! Up to Norm Pennie's speeds of 80 MPH. Quote
dpollo Posted September 3, 2017 Report Posted September 3, 2017 You even remembered to drive on the Left hand side of the road after passing through the peace arch as I recall. Quote
Dodgeb4ya Posted September 3, 2017 Report Posted September 3, 2017 Drove on both right and left sides as that panel wandered like an old drunk at anything over 65! 1 1 Quote
