Eaton fuller 8triple L with 3rd in the four slot.

It looks odd, but one of those Ls is the normal low gear in that transmission, then the two smaller ones would be the double lows that are from the deep reduction part of the transmission. I have seen both shift patterns for 8LL, do you know if that is the original transmission in that truck?

 

I have never driven an 8LL but looking at that shift pattern, it looks like an 8LL is basically a 15 with only one deep reduction gear instead of 5?

 

Deep reduction works on all gears, R, L &1-4....

 

Rank I think they did it because 15 sounds more impressive than 10 LL

 

A 15 has 15 gears but only 11 sequentially higher ratios (shifts like an 11). If my tired eyes are reading that picture correctly, it looks like the 8LL shifts like a 9 speed so I guess they aren't quite the same.

 

I believe you are right

 

I agree 15 sound more impressive than it is LOL.

 

I have gave false advertisement a bunch. I have told folks 15 and 8LL is the the same LOL. But the 15 does have a closer spread and does sound more impressive

 

If you go look, the 8LL is actually in the 13sp style case. I was poking around on something on Roadranger a while ago and noticed they used a shared manual. Wasn't expecting that, but sure enough, that's what they are.
