On the miles per gallon average, I've gotten word from a trusted source they are going to start cracking the whip on proper shifting range, etc.
So, for you newbies especially, keep an eye on your rpm shifting range. They have the ability to see every shift you make via the Sensor Tracs feature. They will call you on this when you go up for review. Get in the habit of shifting by the tachometer. I have been surprised by the number of drivers who weren't taught proper shifting ranges by their trainers and still don't even know what the ranges are and how to obtain maximum fuel mileage.
Western 11 MILES? GOOD INFO INSIDE!

One of things I hammer away at with students is to get out of the lower gears as fast as you can. I barely get my wheels rolling and I'm out of second to third into fourth in no time. You can float those gears easily at 600 rpms. Drivers tend to rev and hold the rpm's up too long on the low side going thru lots, negotiating turns, going up to stop signs/lights, etc. This uses a lot more fuel.
Starting from 5th to 8th I split and shift the gears at 1400 rpms. Going down, I start my downshift or split down at 1150 and bump it up to 1400 rpms for the shift. The other thing I try to avoid is downshifting past 7th low when coming to a stop. The jakes will normally be enough to slow you. I do not coast with the clutch in to my stop, I wait right until the motor starts to lug, then clutch and brake. My miles per gallon average proves that I'm in the zone I need to be in order to maximum fuel average. When a student first starts driving my truck, all bets are off

THIS!
Except the 1400 needs to come down to 1370 no more. This is the number I have been given from above.
This should be it's own thread actually, given that it will soon be a mandate
When evaluating this, they were looking at experienced and new guys to compare shifting and results. My last/best student was one of the new guys looked at, and he was getting 7.6 with all his shifts being right where they need to be. (boy did I look good lol)
It will be hard for drivers with bad habits to change them. Most simply don't know any better. It's much the the same was as them wanting to hire NEW drivers, rather than experienced driver. It's easier to accept "I don't know" than "I don't care" as a reason for a behavior that needs to be modified. -
Eaton/Fuller transmission manuf list the proper shifting range at 1400 rpm going up and 1200 rpm going down which adjust the range 200 rpm per shift. I'll stay with their numbers until May threatens to fire me for not maintaining sufficient mpg average
at which point I will just quit and work for someone else LOL
