Trying to find out when was the first year that Mopar first introduced the 4 spd trans ?? I'm not sure but I think it's sometime around '62, or
' 63
Thanks

T-10 or 833? I think the T-10 was available in some cars in 1963 and then the 833 started in '64.

That is correct
I owned a 4 speed 1963 Sport Fury (383 motor) that came with the T10 4 speed which was not available with either of the Max Wedge motors, they came with a H.D. Borg Warner T86, I think is the correct model, 3 speeds. They came as the original equipment transmissions, not the 727 that were a additional cost option, I think

lol, guess you better narrow what you are looking 4 because 4 speeds in mopars predate the 60's by a couple decades

In cars? If so what year and brand?

The 300-F was available with the Pont-A-Mousson four speed trans.

300-F Four Speed

Thanks for the help
Never say never with Mopar cars and parts, huh
i do remember reading about them(300F 4 speed cars) years and years ago, but I forgot about them
Sniper, what about your information and comments on this

While the car itself was made it was sent to a group with special interests. I would not consider it a production made car because it was not. Now if there was a factory invoice showing the car and a amendment on the invoice showing the modifications then I would have a different opinion. Neat story regardless.

There was ONE that was sent to a regular (very rich, connected) customer. The first 7 were built for Daytona Speed Weeks, all hardtops. The 8th car was a convertible. These 8 cars were also the first with the short rams.

Actual model # was the T85...
Used in the 1962-64 426 Max Wedge cars...

Just my $0.02...

Every Chrysler product built in the 40's and 50's with the overdrive option had a four speed.

The M4 and M6 transmissions, what most refer to as "Fluid Drive" were 4 speeds. It was considered a semi automatic though you could row your own if you chose and they had a clutch.

I worked on a '52 once (can't remember what marque) with Fluid Drive and I could swear that the transmission itself was a conventional three speed with no first gear.

Probably was a Dodge. Fluid Drive was indiscriminately used by Chrysler to refer to anything that had the fluid coupling. It did not necessarily refer to the transmission gear count.

How the semi automatic 4 speed worked.

Wow, that was interesting! Thanks for posting that.

Wrong, My mother had a 1949 Dodge or Plymouth 2 door business Coupe with the3 speed fluid drive tranny on the column, there was only three forward speeds in that tranny, no low gear position on the shifter. You had to start with the gear selector in second and rev it out and let off the accelerator pedal and it would shift into second and then when rev up enough to put in high you shifted straight down it into 3rd :gear (Direct) I learn to drive in that car
I can't remember any Mopar having a 3 speed overdrive option until 1954 or 1955, maybe even later
No 4 speeds except in the trucks

As I said, the term fluid drive was indiscriminately used by Chrysler for just about any transmission that had the fluid coupling. It has nothing to do with gear count.

Chrysler was selling the OD option since 1934. https://p15-d24.com/blogs/entry/88-the-rough-field-spotters-guide-for-mopar-overdrives/

I suggest you view the video I linked, it is obvious you didn't.

Might have a chance to purchase a 1963 sport fury, haven't seen the car yet just word of mouth. Supposed to be a original car, 361 with a four speed trans. Trying to educate myself in case I do get an opportunity to aquire this car.
Thanks to all for your help

In that case you only need to worry about which options were available for that make and model. Educated yourself on what the VIN should say and what the fender tag should look like and you'll be good to go.

Your correct, I had not heard of any O.D. trannys in any early (pre 1948) Mopar brand cars let alone seen, rode or driven one
Not many pre 1948 Mopar stock cars or pickups were around when I started hot rodding in 1961
Ford and Chevy both had O.D. trannies in their cars and pickups starting long before I started driving in 1958

Plymouth for sure used to offer a 3-speed with overdrive at least from 1955 - 1959.... probably only on the 6-cylinder models though. A buddy of mine had a '56 Plymouth wagon that had 3spd w/ OD.

There's lots of confusion surrounding Fluid Drive. "Fluid Drive" became a catch-all term, sort of like how all tissues are "Kleenex" or how in the south, all soda pops are called "Cokes".

The original, and most basic Fluid Drive was a 3-speed with a clutch and a Fluid Coupling. It's main claim to fame was you only needed the clutch to change gears or put it into reverse. You need not depress the clutch to stop or learn how to release the clutch to start off. You could leave the car in direct and drive around all day - just don't expect it to have lively acceleration.

Chrysler's marketing also didn't help much because later revisions were called things like "Tip-Toe Shift", "Gyromatic", Vacamatic, Prestomatic, Fluidmatic, Simplimatic.... it all varied depending on which brand and what year it was.

Then came the M4/M5/M6 variants. The first appearing just before the war was a fluid coupling, with clutch and a two-speed gear box and an underdash, cable operated "Lockout" lever for the under/direct portion of the trans.

Starting around 1948 or 49, a new version came around that did away with the underdash control and a new column selector with "Lo" and "High" ranges; each range consisting of, essentially two speeds.
Lo range was the low gear in the transmission and then cycled the under/direct portion of the secondary box. Hi was direct in the main case and under/direct in the secondary box. Unfortunately, no overdrive but you did technically have four forward speeds.

Starting in '51 (I think) you could opt for a torque converter instead of a fluid coupling; but only on the 4-speed models. The three speed "Fluid Drives" were only available with the fluid coupling right through '54 until the Powerflite was introduced.


That's a quick and dirty history. I'm probably not 100% accurate with dates, or variations. It's such a complex history that smarter folks than I would probably have to sort out.
