leadheavy52 Posted August 17, 2018 Report Share Posted August 17, 2018 I have searched, but unfortunately have not come up with much information, so I once again must turn to the gurus. I have a chance to snag an Overdrive from a 1948 Plymouth. It's local and only $300. Would this fit in my '52 Suburban and are there ways to make it work if it's not an straight bolt up? If so, what should I look for to ensure it is a decent buy? -Austin Quote Link to comment Share on other sites More sharing options...
pflaming Posted August 17, 2018 Report Share Posted August 17, 2018 It won't work, let me have it!LOL I believe it will replace the three speed bolt for bolt. At $300 you have a true bargain. Quote Link to comment Share on other sites More sharing options...
greg g Posted August 17, 2018 Report Share Posted August 17, 2018 Just put one from a 54 in my 46 behind a 56 engine. On a separate note regarding your wheels. Take a look at police interceptor ford explorer wheels. Don't know their dimensions, but the boltpattern should fit and the look remarkably similar to your high clearance wheels.

Plymouthy Adams Posted August 17, 2018 Report Share Posted August 17, 2018 as it did not come out to the public till mid 1952 the OD will be stock for that wagon and retrofit to the 48 the 1951 models dealer installed OD are also considered as stock....

leadheavy52 Posted August 17, 2018 Author Report Share Posted August 17, 2018 Don, I don't know quite yet as I haven't had a chance to check it out first hand. I've got a few reference photos to take along with me. The seller doesn't know much about it either unfortunately, but I'll be there to check it out after work. I'm hoping to use it (if it works) to replace the truck transmission that has been swapped into mine. Thanks for the input (transmission joke?) -Austin Quote Link to comment Share on other sites More sharing options...

pflaming Posted August 17, 2018 Report Share Posted August 17, 2018 Ed, I think the 53/54 have the shorter wheelbase. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted August 17, 2018 Report Share Posted August 17, 2018 no...by 1953 there was a single wheelbase for all Plymouth being 114" Quote Link to comment Share on other sites More sharing options...

Look on the passenger side of the trans mission main 3 spd. case or on the OD housing for a cast in R-10-G for Mopar OD's from this area that do fit your car. Be aware that the tailshaft on the trans can be either long or short depending on if it was used in fluid drives or standard 3 spd. only. If the over-all length of the trans (mounting face to tailshaft is the same). as your current trans . If the # is what is above matches and overall trans length is the same ---BUY IT!! ?

pflaming Posted August 17, 2018 Report Share Posted August 17, 2018 I was unaware that a truck transmission will go into a car bellhousing. I do know that an overdrive will NOT MATE with a truck housing, Quote Link to comment Share on other sites More sharing options...
pflaming Posted August 17, 2018 Report Share Posted August 17, 2018 Some interesting reading. Wikipedia. ' There were two Plymouth wheelbases, with the Suburban riding on the shorter 111-inch (2,800 mm) platform (the Special Deluxe was 118.5 inches)." Wikipedia can be incorrect This comes from Allpar. If K.T. Keller liked the “larger on the inside, smaller on the outside” cars built from 1949 to 1952, the 1953 Plymouth was an even more perfect car for Keller's tastes. Once again, the cars were downsized; overall length was only 1 inch shorter, despite a 4-1/2 decrease in wheelbase for all body styles, while interior dimensions were increased, including greater headroom. Not a single piece of trim, glass, or sheet metal interchanged with 1952 models. The twenty-fifth anniversary Plymouths were caught in a time warp—at a time when bigger was better, they had grown smaller. As other makes plastered on chrome trim, Plymouth took it off, making it an extra cost option on even the most deluxe models. As other makes entered the horsepower race and introduced V-8 engines, Plymouth's only powerplant was the twenty-year-old valve-in-block 6-cylinder (but then 50% of all cars sold in 1953 were sixes). Plymouth was one of only seven makes not to offer power steering, and of the low-priced three, it was the only one not to offer an automatic transmission. While there were some obvious modern updates, including a curved one-piece windshield and rear fenders integral with the body, there were still throwbacks to the old days like the cowl ventilator. For traditionally conservative Plymouth buyers, this was a car with which they could be comfortable. Sales suggested Plymouth was on the right track, as the 1953 models surpassed by nearly 40,000 units the sales record set just two years earlier.

Plymouthy Adams Posted August 17, 2018 Report Share Posted August 17, 2018 (edited) there is the early all steel Suburban built on the Concord chassis...it is 49-52 and is 111 the woody body of the era was on the standard full size Plymouth Chassis 118.5 with the earlier P15 46-48 at 117 HOWEVER in 1953 the Plymouth went to a one size chassis for all models and that is 114......some account this chassis as the best all around smoother and better handling vehicle due to the 114 chassis... I thought you still had a copy of the Plymouth manual, all this is spelled out in the book under General Data and Specifications Edited August 17, 2018 by Plymouthy Adams Quote Link to comment Share on other sites More sharing options...
leadheavy52 Posted August 18, 2018 Author Report Share Posted August 18, 2018 I went to go look at the overdrive transmission from the '48 Plymouth this morning. It was crated up in a dusty and oily old wooden box. Inside was an oily and dusty R10G-1 3-speed, which looked to be complete. The old '48 must have had it installed later in its life (ah the good ol days). It has parts in the box which I assume are a kick down lever and a relay of sorts. Needless to say, I paid the $300 asking price and rolled on happy about my new purchase. This will allow me to get the car back on the road quicker and in more comfort. I spent a little time cleaning it up and it looks to be in decent shape. I free turned the input shaft and was met with a grinding noise, like sand in bearings and decided against turning it more. I'm sure it needs to be gone through as a precautionary measure. Are parts for these impossible to find, and if found, do I even want to know the price? Here she is as I found here and after a little cleaning. - -Austin Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted August 19, 2018 Report Share Posted August 19, 2018 $300.00 is a deal... but if the OD planetary is seized up... that'l cost you. There is a quick way to test for OD operation to be sure the OD portion works...remove the solenoid...two1/2" bolts ...rotate solenoid 1/4 CCW pull outward to remove solenoid.. Now insert a screw driver down into the solenoid pawl and as you rotate the brake drum back and forth push the pawl all the way in ... you should feel the pawl drop down a 1/4"... When it ( solenoid pawl) does drop down. shift the trans into 3rd gear and rotate the input shaft .... the brake drum must turn 30% faster than the input shaft.
