I have been informed that the mystery gear does not exist after commenting in "tips for driving a tip truck " thread. Well does it exist in the high range! you tell me, Yes or No!.

Mystery gear!Is it 18 plus 1! Is that the gear that is a secret to all but a few! How can anything have a mystery gear! Must go check my bike, it may have one as well. Or is this just a truck thing!

It is just a truck thing.) Funny though the guy how said it doesn't exist was also from Gore.

on the fuller eton noin the bottom box maybe I drove trucks with enough horsepower not to need that low in the gearbox not sure about the roadranger didnt drive a jappa with an 18 though and as gunhand said anything is possible in a jappa

it is the "LO" gear, it's just commonly referred to as a "mystery gear".

Yes "mystery" gear is there its below R in a 18 speed. When in low range its a sort or deep reduction for serious hill starts or when you need to inch foward- when first low is to fast. BUT when in high range its "mystery" gear. DONT use it in high range! I was told it dosent have sufficient bearing support for high range use, and buggers the gearbox over a period of time! Just because you can- dosent mean you should- Just because it dosent go bang straight away, dosent mean it wont.

Look on the shift pattern sticker. nothing there in high range on the Eaton/RR shift pattern! BUT in low range on the sticker is has."LO"

Well that answers that then. The almighty has spoken. I'm off to look for a large hammer.

Are you off to get the hammer because you doubt what I said! Read the owners manual of your truck before you fluck it.

You are so right,
The guys who designed and built these transmissions know more than these dickheads, Otherwise they would call it 14sp and 19sp wouldn't they. There is a gear there but dont use it.

Actually, on the ones I've driven, there is a "LO" and "HI" on there. i.e. LO LO and HI LO.

What speed gearbox! not a 18spd Eaton/RR Im guessing
henderson_guy,
Nov 27, 2:28am
yes 18spd eaton.

Actually, come to think of it, you're right, it was a splitter select, not a range select. At any rate, I never used it. At the moment, however, I'm driving a 15 speed. What a shit of a box.

Mystery gear in high range gives you roughly low 3rd and getting out again is tricky

Right you are then.

a 15 speed RR

Not a bearing issue, no individual gear in a rr has a bearing the mainshaft floats unlike your usual single countershaft syncro. The box will have more load on the bearings on low range anyway, we are pulling 170t with them behind 620hp and they outlast the diffs and engine, probably the best gear box ever built.
Not doubting ya Phil but have built a few of those boxes and cant see how high range will bugger it but might be different in the real world after extended use who knows.

it was with the old 13 spd knob,you could split the highest gear in low range,forget about anyone talking about 15 speeds,they are not a splitter box,the newer roadranger gearknob you cant split a 13 spd in low range,18 speed is different,where as you can split any gear.
