I was surprised it didn't bust a U-joint. The single drive axle started hopping up & down. At a red light near the terminal, I saw a guy tach out his engine & then dump the clutch. Lots of guys would deliberately try to tear them up. All the ones I drove at Roadway had to be clutched into neutral because it was impossible to get to that "no load" point on the throttle. Sterling trucks have a serious problem with that. If there's pressure on the gears, you won't be able to pull it into neutral unless you either slow down below your governed RPM range & tap the throttle to momentarily pass the "no load at all" point, or step on the clutch. The reason it gets stuck is because the RPMs are now higher than the computer will let it run, so there's a negative load on the gears, meaning the truck's inertia is pushing the engine, instead of the engine pulling the truck. But if you exceed your normal governed RPM and then ease off the throttle a little or linger too long above that range and the computer cuts the power to limit RPMs again, you can get stuck in gear & have to use the clutch to disengage for your upshift. On a Cummins, under hard acceleration it'll allow you to momentarily exceed your engine governor limit. Whenever I do try it w/o the clutch, it won't come out. Anyways, I can't seem to get from 5th to 6th without having to use the clutch. It only takes once or twice to loosen it up.Ĭlick to expand.Are you talking about the RPM limiter? 1 Currently, I have a CDL permit (been driving since September, have taken and failed DOT test once). So in that case, if the transmission is stone cold & been sitting overnight in freezing temps, flip the range selector up & down a couple times before you start driving. you just started driving it in winter temps & it's the very first time since you started moving that you tried using the range selector, there's about a 75% chance the range selector will be stiff & slow. On a 13 speed, when the truck is cold, as in. Just to be a smart-ass, I started calling it an accelerator instead. You don't "step on the gas", you "step on the fuel". He said "it's not a gas pedal, diesels don't burn gas, it's called "fuel". this one is not important to passing the test but it's something the instructor told me when I was learning. ![]() I've been driving trucks for almost 10 years & I have no idea what DubbleD is talking about with the computer thing. Having already gotten used to floating, you'll have a bit of a handicap so you'll have to put more effort into learning double-clutching. Floating is way easier, but if the state requires double-clutching you'll have to learn it. find out if your state examiner requires double-clutching to pass the test. An old timer told me once that it's not good for the trans to do it that way, but it works & you can pass the test & then worry about learning to do it "the right way" later, after you have a job. ![]() By the time you can move it from 5th to 6th, with a Cummins, the RPMs should fall enough it'll go right into gear. ![]() Click to expand.Flip the range selector up while you're still in 5th, then let off the fuel & immediately shift.
