A Little Lingo Help Please

On a 13 or 18 speed, direct and over, mean Direct and Overdrive positions in the auxiliary portion of the transmission as selected at the gear shift with the splitter button. These days they are usually referred to as L & H ie. Low and High in the past the shifter knob was labeled Dir. & O/D.

 

On a 10 speed Overdrive, top gear is "over" and 9th gear would be direct.

As in direct drive. Meaning the gear reduction is 1:1. So that the output shaft of the transmission is equal to the input shaft speed, ie the engine speed.

In Overdrive, the output shaft is turning faster than the engine.

 

Lolo...MANNNNN..I HV ONLY BEEN DRIVING..OTR. 10 SPEED FOR 2 YRS...AND 9 SPEED DUMP TRUCK FOR 7 YRD ABOVE GROUND MINING CO...I NEVER NEW ANY OF THIS LINGO YOU GUYS ARE TALKING..NONE BESIDES DTOP IT IN THE HOLE....LOL...WOW...GUESS U DONT NEED TO KNOW LINGO IF YOU ASK THE RIGHT QUESTIONS...THANKS GUYS..

 

5th direct would be the same as 9th gear. 3rd over would be 6th gear 18 speed transmission. You must be watching IceRoadTrucker Season 4.

 

God help us I hated that season because of that kid. Last episode I caught was when he was talking to that driver about being tail heavy and spinning out.

But as for direct and over they refer to 13 and 18spds. 3 over would be...uh...8th if I'm not mistaken that's counting low as 1st and 2nd gear. I don't use low unless I have too and it all gets pretty confusing I have respect for anybody that can actually count them off. And put numbers of the actual gears where they belong.

 

I was thinking Season 4 when Lisa gets her first chance at push trucking with Jack and Carey. Season 4 was the last good season.

 

After watching IRT I'm almost embarrassed to admit I used to haul over the Dalton.
