Location: Piedmont, Oklahoma | Ive acquired a 3 manual trans with an overdrive from a 55 Dodge. Is that just a four speed? Ive tried searching around for some answers on the web but got conflicting answers, so I defer to the masters. Thanx, Brent |

| The overdrive is a Borg Warner and was used by Chevy, Studebaker, and Ford too. See, http://www.studebaker-info.org/tech/transmission/BW-OD/bwoperators....
and http://www.fordification.com/tech/overdrive.htm
The standard transmission is a selector type 3-speed. See, http://www.youtube.com/watch?v=-kRzKd9NY5o

Every era 3 Speed Transmission and era Car/ Light Dodge Truck 3 Speed with Over-Drive is always a "side shifting unit". This unit will have an Electrical Solenoid to be used.
There was never a 1946 to 1966 Floor Shifting 3 Speed anything MoPar.
The era 4 Speed Transmission that was use in Dodge Trucks is A Top Shifting Unit and weighs as much a bag of Contractor's Cement.

Location: Hayward, Calif | This was a good trans for the 6 cyl and small V8's. But a 392 will split it open from end to end. Just the voice of experience talking here. Jerry |

Location: Under the X in Texas | I see some hobbyists today calling a manual 3 speed with overdrive "a four speed". Technically they are wrong as a transmissions gears are numbered by how many combinations are available within the main case or box. Thus, its a three speed transmission you have. The overdrive is a bolt on additional gear box.
Yes, they could argue there are a total of four speeds, but it is done with two gear boxes. |

| A lot of times that bolt on box didn't get serviced with gear oil, the mechanics didn't expect they had to fill two separate compartments. As a result, one would eventually starve for oil and burn out. |

Location: Alaska | Rodger, I must correct your statement. Chrysler & Desoto had a factory 3 speed floor shift in 61-62, possibly also 60. The Borg Warner 4 speed was available w/ floor shift in 63 and the Mopar 833 4 speed from 64 on. I believe the Valiant/Lancer also had a floor shift in 61-62. |

I have with-in reach of this Key Board a De Soto 1960 Factory Service Manual and a De Soto Factory Service Manual "Supplant". Neither of them have a Clutch Section -
A Manual Transmission Section nor A Manual Transmission "Shifter" Section.
The Chrysler Corporation had already closed The De Soto Division before this month in 1961 --- so there was never a 1962 De Soto.
-----------------
My 1962 Chrysler Factory Service Manual does show a 3 Speed Manual for their Newport's ( SC1 ) and 300's ( SC2 ) with a Floor Shifter.
---------------------
My 1962 Plymouth Factory Service Manual does show a 3 Speed Manual for their 106" and 116" Wheel Base Cars. It Does Not show a floor shifter.
----------------------------
By "era" I was only thinking of the time(s) of his Transmission Question.

The Max Wedge came out in late '62 so some early parts manuals won't show the floor shifter used on the MW T-85 3-speed. This carried on through '63 and '64. The '62 3-speed shifter was in-house, the '63 and '64 were Hurst. |

Location: Alaska | I was not sure about the Desotos, thought they may have offered an economy model like the Newport in 61. I am aware that they ended production in early 61 MY. I also thought the 61 Valiant had a floor shifter (not sure) If you can find one, the 57 Plymouth 3 sp. OD is a better trans. than the selector type shown by Hoodinki but still too weak for a hemi. (or even a 318) The real trick would be to find a BW T-85 OD unit (most likely from a Ford) and modify it to fit your mopar. They are much stronger than the factory 3 sp. offered in the Forward Looks.

Location: bishop, ca | And, here is some interesting facts on the 60's manual transmissions...
The 1962+ versions were maybe not strong enuf to support a 426 Hemi, but they were not really a 'weak'
transmission.

Location: Hayward, Calif | That 3 spd O/D trans in reality had 6 possible gear ratios. 1st speed, low and high,,,,,,,,,2nd speed, low and high,,,,,,,,,,,3rd speed, low and high. 1st speed required a lot of rpm to go fast enough to allow the governor to hick in and allow the overdrive to shift. I had one of these back in early 60's and got a kick out of playing with all the possible gears. But it won't take the shock of a high torque engine. Jerry |

Most of the OD units were built by Borg-Warner and there were at least a couple of different sizes...the R-10 unit was used behind the lighter duty transmissions like the T-86 but the R-11 unit used behind the T-85 is actually quite durable. I've adapted the R-11 OD to the 727 Torqueflite and used it behind some potent big blocks with no problem.
