To drive it properly, going 100 yards to the mailbox requires precisely 87 shifts. You can do it in 83, but you have to rev-match and run slicks in the rear.
No it's the mack edition cause macks used to have some crazy gate patterns and trans setups lol first truck I drove was a 74 mack duplex it was 4 over 3
Loved tis tranny. Had my '88 for over 30 years and approx. 120,000 miles. No problems and if in the city I would start is in 2nd low gear and hit the button to go to 2nd high, never having to touch the clutch - essentially making it an auto tranny for stop and go traffic.
I've heard about this transmission in several car magazines. The editors DESPISED it. It was clunky and so confusing to use. They were overjoyed when GM moved to the ZF 6 speed manual.
It definitely makes sense to turn OD off, then back on after reaching 4th. It shouldn't be as complicated as driving a Semi Truck with 13 -18 speed transmissions! 🤣
I spent almost two decades in the automotive repair industry between y2k-2018 and never heard of the 4+3 until the 24hrs of lemons guys talked about one last week since someone raced a vette with that trans. Apparently it held up great while the rest of the car predictibly fell apart. Now you're talking about it here. Crazy.
My dad bought the turbo Chrysler Laser when they came out (can't remember the exact year his was tho) which came from the dying dodge charger daytona and went on to become the plymouth laser that then became the mitsubishi eclipse. That was weird time at dodge.
Gear venders makes a electric actuated bolt on overdrive/ gear splitter for almost every manual transmission and various automatics that does the same thing. I still have an old manual overdrive unit that bolts between the bell housing and transmission giving a twin stick setup. Got 7 gears out of a 4 speed
I have a 4+3 myself and that would require more effort than what it's worth. Not to mention rather silly. The car has enough torque you could skip gears and it would not miss a beat.
4 speed plus overdrive was very common in many car manufacturers until the 70's and 80's when the 5 speed took over. But I'm sure Volvo kept the overdrive function longer than most.
Exactly, should be perfectly fine to drive this transmission in the same way as your would with the Volvo. The same trans was also used in early 740/760.
It kind of reminds me of the 3 speed automatic my 1995 Base Plymouth NEON had. Once it reached a certain speed, the torque converter would lock up, acting like a deep overdrive 4th! 🤣 I remember my Grandparents on my Dad's side 79 Dodge Aspen with the slant six with automatic doing the same thing as my NEON.
Would love to find a first year Neon stick in good shape. People hated those cars, but when Hondas were putting out 90hp stock, they were definitely ahead of their time.
I have been driving manual transmissions since 1973 and have never owned an automatic. I have never seen such a strange manual transmission until this video.
Also don’t try to use overdrive for actual acceleration in any normal car, otherwise you’ll ruin the engine because overdrive is meant for cruising and not actually accelerating.
Great point any trans with an external OD (which this example is) has exponential stress on the output shaft/bearings when the OD is engaged. There's a bit more to it than demonstrated here.
Got to love the thought and time spent developing this technology. Don’t forget the high tech radio, gauges and all the knobs!!! I remember the speedometers like this, In high school a buddy of my had a Pontiac TransAm or Firebird with Tach and Speedometer like this. It was very cool back then but not so much today!!! 😂, still a cool car.
I had one of these. 1987, 4+3. It was a blast to drive, even if you shifted from first gear to second gear, and then second gear overdrive, and then third gear, and then third gear overdrive, and then fourth gear, and then fourth gear overdrive. The transmission didn’t love being used that way, And the other way described in this video was probably nicer on the clutch. At the time, this was the fastest car I had ever driven. Before that, I was driving a 1985 mustang GT 5.04 barrel carburetor, 5 speed. But this Corvette blew it out of the water. It’s hard to believe that there are yet two other vehicles I’ve driven since then that blow this out of the water.
This is exactly the type of thing I would expect to hear from none other than a corvette owner being said to their wife that is in labor while in the back seat of a taxi cab stuck in N.Y.C. traffic at 2:17pm in July just as the babies head is crowning.
I daily drive this transmission and it’s great because the 4+3 overdrive allows you to keep the RPMs over 5000 the entire time you are racing overdrive and second gear goes higher than third so when you’re in second overdrive and you’re red lining you can literally go up to third to drop the RPMs back down a little bit but not all the way so it’s great for racing!
It can be even more confusing is down shifting. And you have to do all of this without looking down. Can't take your eyes off the road. It's just watching your Tak or red line. It came be fun, but it takes talent.
Read car mags for years. C&D, R&T, MT, etc. I don’t remember hearing about a transmission like this. Interesting, but I can understand why it didn’t have wide adoption
I loved the 4+3 in my 84. Unfortunately, reverse gear went out twice which was a common failure with this transmission. Other than that it was really fun to drive.
This type of transmission reminds me at one style used in first-gen Twingo. However, the Twingo case was a automated manual transmission that the sequence to change gears is simillar at the sequential transmissions of racing cars. And this Corvette don't equipe this peculiarity, since the sequence of the "sequential" transmission is inexistent... But compense in the moment at change first to second and with the second push more the gas and low at first gear. Or this is that i'm thinking.
Even more complicated than a 13-speed semi truck. On a semi truck, you can start with 2nd or even 3rd and skip gears as long as you are not lugging the engine.
Another odd gearbox - Mitsubishi had the "super shift transmission". 8 gears. A normal 4 speed gearbox plus a 2 speed transfer box - "power" for better acceleration and "economy" for lower rpm cruising.
Strangely the old medium duty trucks with a two speed rear end have similar goofy shift patterns (but power starts at 1500rpm with a 2500 redline so doing the process is required unless the truck is empty!) Not really sports car material.
They were usually 4speed carry overs with real hydraulic overdrive attached to the rear of units which gave maybe 15to 20percent real overdrive. Which was great with the right gear and engine for the highway.also you were not supposed to just push the button without clutching like what I've been reading that some did or would do because it would burn the unit out prematurely by slipping the clutches in them😂
Seems legit. I see it in the Fast & Furious movies all the time
Hahaha!
10 shift races with huge acceleration bursts after every shift...

Need a video shifting ALL Gears
That might be hard to do. First, you'd have to find one that works 100%.
I always wonder about this 4 + 3 transmission 🤔. Thank for education. Reminds me of dump truck with a high low rear end.
Drive it like it's an Eaton.
The Toretto transmission. Nobody knows how many gears she has 😂
This deserves way more likes, possibly its own dedicated r/reddit
Lol, the transmission doesn't like doing that ... thats funny, because that transmission rarely liked to do anything ... like work at all ...

Thanks, Kase, who had the Dodge Colt (Mitsubishi) of the early 80s with the twin-stick power & economy. Miss that little car, now seems like a go-cart

He can't, that would surely blow the trans up.

you could wire the solenoid to have overdrive in any gear you want, same as this transmission has
The borg warmer r10 overdrive did this same thing on the old ford transmissions
I mean…it was a helluva interesting idea that’s for sure 😂
I've always wondered how those worked. Thanks for the info. It drives like a wide ratio four speed until you get into the throttle. Cool
It kind of reminds me of the 3 speed automatic my 1995 Base Plymouth NEON had.

Both were probably just about to take a dump on you.
Man that's is a weird gear overdrive transmission 😮 that's cool tho

Challenge accepted!!!
Corvettes will always have the best digital dashes when they were being used
You never drove a big rig. We do this all the time. Look up an Eaton Super 10
Cool story bud
Man this feels funny, those old ass displays that still keep up with modern ones, mixed with the weird shifts.
A manual transmission with kickdown. That's such a badass idea.

That's an awesome gauge cluster
I think these old 4 speeds are going to be very (if not already) desirable in the future cause most people want the newer 6 speeds.
I can picture taking this thing on ur road test 😂
Looks futuristic

I would be confused as a passenger seeing it's stick shift and then feeling it shifts for itself. It's like half-auto half-manual.
That is so different, I’ve never seen anything like this.

Car dash looks like an airplane cockpit 😊
Gear shift is built for a piano player but if you could get it right you can definitely make that transmission sing
I thought that was a Pontiac firebird for a second-
My 51 Ford has a 3spd OD transmission in it. While you can get it to go into OD in 2nd.... you have to push it hard to do so.

I just drive as a 4 speed most of the time only need od on the highway. The kick down works just like an auto. It's weird but pretty neat
Its like drivin a semi truck! Hi low double overdrive!
Somewhat like an old merc. Although I believe the ratios worked out so you could go 2, 2od, 3, 3od.
Better than the 1 to 4 six speed that had a gate forcing you to shift into 4th a light throttle input. Just YUK.
The strangest transmission I’ve seen is the Citroën 2CV
And I thought the dog leg gearbox on an 190E cosworth was weird.
Don't forget to double clutch between each shift. 😂
Similar to Volvos 4 speed + OD except on that one overdrive can only be engaged on 4th gear. The kick down feature is interesting...
