Spicer used to sell in the US and TTC (Tranmission Technologies Corporation) still sells in Mexico, 14, 16 and 18 speed transmissions that used a base "5" gear pattern like the Super 10 but had a four position splitter button instead of the two position on the Super 10.

On the 14 speed, you split gears 1-3 twice and gears 4-5 four times to get a total of 14 ratios.

On the 16 speed, it was the opposite, you split gears 1-3 four times and gears 4-5 twice to get a total of 16 ratios.

On the 18 speed, it was the same as the 16 speed except you split 4th gear four times instead of just twice.

Each transmission offered 4 reverse ratios.

 

I hate super 10's, personally. I had to drivers tell me how much easier a Super 10 is to a Straight 10.

You can still skip shift the lower gears with a straight 10 and you only have to split once going up and once going down.

But to each their own.

 

What it boils down to is this:

It's a 5 speed, and each speed that is selected with the lever can be split lo or hi with the air shift button, for a total of 10 usable ratios.

(It's the same as driving a truck that has a 5 speed transmission and a 2 speed rear axle)

 

Boy.... A super 10 is one of the easiest transmissions you'll ever drive. to me, It's like a simpler version of the 18 speed.

Just think, it's not nearly as hard to learn as say, a MaxiDyne 2 stick system or the old, (and personally hated) Quadruplex.

 

Nah - pushing a button marked "D", letting out the clutch and heading down the highway is easier :wink:

 

True....

I forgot about the automatics.

 

To each his own, I guess.

Personally The Mack Quadruplex is my favorite transmission of all time.

 

you must be patient and let the transmission complete every button shift, because if you get back on the throttle before it completes the shift it will just stall. once i learned i loved it.

 

I just never got the hang of shifting the quadruplex.

MaxiDyne.... no problem.... It's self explanitory. To me, the Quadruplex needed a 200 page manual and the driver needed 3 arms. My dad had an old DM that had one in it. I used to get a kick out of watching him shift one with his right hand while shifting the other with his left arm through the steering wheel.. HILARIOUS...

Definitely not for a one armed man..
