But anyway they have 10 speed Eaton transmissions with C12/13s, boy do they shift and cruse nice compared to our farm truck. Trucks at work are CATs, they pull the best at 1200-1700 or even little lower, when pulling up a hill it will actually fall to about 1600 and just run all the way unless your to high a gear. If you start out from a stand still with a load you will notice that is where it has the most power. I run it up to about 2000 rpm or close and let it fall to the 1500 range when i shift. I have an L10 with 9 speed splicer so similar in one way but i would not recommend a splicer anyone, very hard to shift, so your much better off with Eaton.

I'm not a pro by any means but I've got it figured out and even down shift pretty good Sounds like me a few years back when we got out first semi It's all in matching the rpms to the gear Posted 19:49 (#4509340 - in reply to #4509317) Subject: RE: Shifting a nine speed-old dog learning new tricks No2 Shift at lower revs when in low range or when running empty. tap the clutch lightly and shifts will be much slicker. No.1 Use your clutch, but do not depress clutch fully when shifting gear. Posted 19:41 (#4509317 - in reply to #4509195) Subject: RE: Shifting a nine speed-old dog learning new tricks each engine and transmission combination is a little different t but you can tell by ear with or with out a tach I have shifted a Fuller RTO 6610 a few million times in farmers fields. some times you have to double clutch in that situation. The one situation that is hard to do is soft ground off road. with experience you can feel if your rpms are too high or too low. you can feel the sliders grinding of your rpms are too high or too low. then with the tranny in neutral rev the engine to the rpm it would be at in the gear you want it in say you revved up to 1900 rpm neutral drop it to 1500 rpm and ease the shifter into the next gear. then level off so a smooth speed ease up on the throttle to make pulling into neutral easily. When not using the clutch first you accelerate.

Definitely drives easier loaded and usually only the 1-2-3 shifts in low need a double clutch. Depending on the trans temp and my mood, sometimes double clutching is easier than floating the gears. We have one l10 and 9spd here, and it might as well have an on/off switch for a throttle. Put a load behind you and rev it a little more.

Posted 18:57 (#4509228 - in reply to #4509207) Subject: RE: Shifting a nine speed-old dog learning new tricks I have a Cat in a Sterling tandem and it is a breeze to shift because the rpm's fall slowly, just remember that the rpm's have to drop 400 before you can shift, it just takes some practice. I have an '05 Pete tandem with an ISM Cummins and a 10 speed, the Cummins is hard to shift because the rpm's drop like a rock when you let off the throttle, I have to rev mine to 15-1600 and then shift quickly. Posted 18:56 (#4509226 - in reply to #4509207) Subject: RE: Shifting a nine speed-old dog learning new tricks Lose speed pretty quickly to synch with rpms. In low range, especially empty, you have to be pretty quick on the on the shifts.

Once I get it in high range I'm getting decent at shifting without clutching, but this slow speed stuff is giving me fits. I'm having a terrible time shifting in low range especially 2-3-4. Just bought my first semi, a Kenworth with an Eaton Fuller nine speed. Posted 18:44 (#4509195) Subject: Shifting a nine speed-old dog learning new tricks
