    Can You FLOAT GEARS??
    You CAN SKIP GEARS DOWN-shifting (just like UP-shifting), don't need to "hit every one". Every transmission has a "Comfort Zone".

    Like mentioned in Post 10, Start Slowing Down On Interstates, It's Not A New Concept.
    IF Ya keep "slowing down Just on Ramps", You'll either Smoke Your Brakes, Another Vehicle and/or Your Vehicle! THEN it gets expensive!
    Pay Attention to the MINIMUM SPEED LIMIT on Interstates as You CAN slow down to that speed before exiting especially on SHORT RAMPS as well Ramps with CURVES.
    It's called SAFETY!!
    Trucks don't like Sharp Turns &/or Short Ramps at High Speeds.
    The Life You Preserve May Well Be YOU!

    On Secondary Roads with Stop-n-Go Lights, As You're Able, Watch the Next Light As I've Discovered Un-Countable times it usually flipped RED Just a wee bit before unable to stop as I was decreasing some speed. I preferred "heating up the brakes" to avoid "running a light" and gathering a Cop or worse.

    Ya don't need much air lifted seat to comfortably Drive a Pete, KWhopper, Mack, Ford, Cornbinder, Freightshaker, or volvo. Lower the Seat, Lower the Steering Column.

    CHEERS!!

    You don't have to hit every gear as you downshift. You could do 10 to 9 to 8 to 6. Or any combination you like but you don't have to hit every gear on the way down.

    Okay thanks guys!
    I will start slowing down more than i have been prior to exits and stale lights.

    Idk why i havent thought of skipping gears down shifting! Lol
    Just used to what i was doing in school.
    im gonna try it out 10-8-6 or something like that next drive.

    im out in the sticks and these exits or turns come up quick sometimes in the dark. Were not using gps as i was told specifically not to use it since the well pads we go to are just not on gps. As for the clutch peddle i think im fine. Drove a different truck yesterday which is actually going to be mine and didnt have as much of an issue with the other truck. And yea i got the jake brake and have been using it mostly in mid and high range. Pretty awesome tool to help control my speed.

    got it wrong btw on the model. Its a 388 not a 389 but not sure it makes any difference on the controls and such..

    thanks for the help so far. Just trying to become a safe and skilled driver.

    388 and 389 have the same clutch set up...
    As stated earlier JMO
    . But I love the Peterbilt clutch concept.. if the linkage is good and the clutch & clutch brake are properly adjusted it works great great !

    Clutch brake is supposed to be all the way on the floor. You are almost 6 foot and cant reach the floor???? Im 6'4" tall and am cramped in my 379. THis sounds very fishy to me. No offense but how are you almost 6 foot and cant reach the floor with the clutch with the seat all the way back and let alone all the way forward. Do you have like a 4 foot torso and really short midget legs? Just doesnt make any sense at all imo

    These seats have been re bolted to the floor (moved back) on several of these trucks so no longer the factory position. The truck im in now is fine (but actually still not bolted in its factory location. Truck i was in prior was re bolted way back for a big guy and I think maybe that was my problem... Or its just the weird action of the clutch coming from the floor that I couldn't get used to right off the bat? Either way the freightliner in school was way different and I kinda preferred how that clutch worked.

    I will use my left foot on the brake while downshifting as you describe. You don't have to hurry your shifts, and it can be done quite smoothly.

    I also do this if I need to downshift on a grade.

    Two-foot drive in a semi if you need to. You're not using the clutch anyway, so you can brake with your left foot, and control the throttle with your right foot. If you drive an International, you can do it all with one foot, because the brake and throttle are close together.
