13 Speed: Probably a stupid question, but...

W. T. F.?

 

Hahaha...that's the trans I learned on in cdl school.

 

Think i had a Toyota with that pattern.... cept 9th n 10th were swaped...

 

All I could find on it...fwiw..

"Spicer 1453 and 1241D=2 into 1...20 forward gears with a single stick"

 

I miss driving mine although I only drove it to truck shows.

 

Is that the spicer trans with the blue knob and 4 position splitter?

 

A 10 speed is just a 5 speed with a hi-low range brownie on the back of the trans.

A 9 speed is a 10 speed where 5th and 6th are essentially the same ratio.

A 13 speed is a 9 speed with the ability to split (double the ratios) the top gears in half with another gear set in the brownie built into the back of the trans.

A 18 speed is a 9 speed that allows you to split all the gears instead of just the top 4/5 in the box like the 13 speed.

 

Seriously...I haven't a clue.

 

Would love to see the shifting arm of anyone who drives this.

 

Lol. 15 speed but progressive shifting from 1st in DR to the top you'll only use 12 of them.
