Got fired for not floating gears

My guess would be the grinding noises were audible from 3 blocks away.

 

On the bright side: If you double clutch straight in to a gear without fealing resistance while progressive shifting, then it means you basically know how a lot of stuff works in precise detail.

Floating is a way around remembering revs and road speeds. I passed my road test in school using a 9 speed which I never drove by making it look like I was double clutching while floating. It was a fail if you floated; my old teachers didn't even look at the dash while doing it

 

I will say this....I have owned/driven trucks on and off but more on for 25 years. I have driven exactly 1 with an ISX just so happened to be a 17 model W900 with an 18 speed. To say I was less than smooth is an understatement. Drives nothing like the CATS I have had all my life. As stated a time and place and situation dictates procedure. I wouldn’t let this bother you. They didn’t give you any chance to get used to the truck. No 2 handle exactly the same

 

I have two old trucks with mechanical Cummins 855’s both with 13’s. The one I drive the most falls/returns to idle while up shifting faster then the other and has faster throttle response for down shifts. This makes for smoother shifts even though you have to shift faster. The other one returns much slower and will hold its rpms up between gears much longer which makes it a much different style of approach to shifting it with the same exact trans. Both require different speed and timing between foot and hand.

If you wanna really learn patience with grinding gears? Shift anything behind an old Cummins NH743-220. Because of the external injector fuel lines they have the slowest throttle return between shifts even when pumps are set hot. They shift slow compared to any other Cummins made since them.

 

They sure pick up and drop the RPM quick compared to a Cat or even a Series 60.

 

Not to mention the rpm drops and throttle response difference between mech and wire. If peddle is set right a mechanical is instant at the wiggle of a toe. Some ecm’s let you bounce on the peddle before it responds. Do that with a rod connected to the throttle shaft and it sounds like a drum solo. Brap brap brap brap!

 

Clutch for 1st and Reverse only. That's how I learned. It is very rare I use the clutch for anything else.

Double clutching? I think I tried it once just to see how it works.

 

And all this time I thought you were a Staff Sergeant.......

 

Are newer Detroit and Cummins even physically connected to the accelerator? I thought the ECM took analog input from the pedal and controlled an actuator.

This would explain the delays
