    Hi guys, quick question, I’m about to drive a semi truck bob tailing from Texas to NC. I’ve never drove an 18 speed. I’ve been told I can just take it to 9th gear then flick the side button up and drive on home. Is this true? Can I go 75 mph like that? Sorry If Im not explaining myself correctly. If I’m not can y’all explain how to drive home bob tailing ?

    Yeah, if youre bobtail you can just shift it like a 9 speed, flick the switch forward before you even start your trip and forget about it... Leave the switch there and its a 9 speed.

    You can drive them just like a 9 speed, flip the splitter forward and go. I've driven mine that way loaded.

    So before I get on the road, flick the switch up then drive it like a 9 speed? My cousin told me to drive it like a 9 speed once I get to the 9th then flick the switch .

    Then 18 Speeds were the last stop over before the 12 Speed Autos, correct? Shift until 9/13, move splitter, and then its auto from there, up and down, until 9/13, then move splitter and shift down to stop after leaving the freeway and stopping at the bottom or the ramp? Or actually stopping anyplace. I have never driven a manual over 10. Glad Original Poster (OP) asked this question. Good to know.

    So I’m guessing if I flick the switch before driving I’m in the highs ? And if I flick the switch last, I’m in the lows?

    The grey switch on the side…forward is overdrive, back is direct drive. Being Bob tail you can run in over drive all the way threw the gear box, so yes push that baby forward & run her like a nine speed

    Gears and switches are there to be used.

    Use em.

    Except for granny gear.

    I leave mine in overdrive due to the fact the speedo is lazy in direct. I climb hills at 15 mph in one position. When I'm doing 45 mph in the other position.
