Since I inheritied I don't drive alot and never heard of that?

The trailer helped him alot. Guess they really are designed to have some weight on them. Then we practiced down shifting and the jake on high really screwed him up, but the trailer was empty. Not winding it as tight seemed to really help. thanks again.

Forgive me for a possible ignorant question. But why should you use the clutch? I have driven many 10 speed Eatons and never use the clutch. Infact I have operated a 330 Pete almost daily for over 4 years without clutching between gears. It seems like once you learn how the truck drives, the gears simply fall into place. No grinding etc. I have been driving for 15 years and was self taught, so I could very well be doing something wrong. Now that I think about it, I can't remember a time that an experienced driver has ever riden with me. Thanks for the advice.

He is just learning his self and I only use it when i screw up to take the touque off. All he had ever driven was gas trucks and a few of our trucks and not very well with the standards. My duel disk still give him fits.

Ok thanks. Just wanted to make sure I wasn't doing something wrong. Hope he gets the hang of it soon.

I seem to have that problem when operating machinery!

what engine is in it and is it a program truck or self owned truck
you can talk to dealer and they will give you practical rpm range for specific engine unless you have some fuel saving program installed in the engines computer

most problems are generated because of wrong rpm's when shifting

WHen I started driving I had 10 years in our dump trucks already. I teamed with another new guy whose training had all been in a cabover IH. He would come out of gear, flick the lever around, then use the detent to find his next gear. WHen he got in the Century class freightshaker, he couldn't hit a gear, the detent wasn't heavy enough for him. I finally had him hold the top of the lever while I moved it from the bottom of the cap, and floated a couple gears for him. He hit every gear after that.

I drive a 13 speed now, and a 10 screws me up if I have to use one. I never could get a 5 speed spicer.

The faster the countershafts are turning the harder it is to shift. Keep the rpm's lower and it is easier. With a front box od the shafts turn about twice the speed and are therefore harder to shift. Also I have trouble with mine when the trans is cold. I never use the clutch....

From my exp if a guy can't get "basic" shifting down in one day he never will. Not saying I don't ever miss a gear or scrub one from time to time. Honestly the trans that gave me the most trouble & would refuse to own or drive is that 7spd mack. Two sticks are easier than that thing. My fav trans are 8LL or a older 15spd. I've rode shotgun with several guys "learning" & maybe 1 out of 5 got to come back to work the next day. Shifting is like running equip you can either do it or not, can't be "taught" ,least thats what my grandpa use to say!

I'd have to agree with that. You either have a feel for machinery or you don't. It's not a skill that can be taught to everybody.

On a ten speed, take the rpms up to the point you want to shift, slip it out of gear, let the engine drop 500 RPMs and it will slip right into the next gear, Same way to downshift, just backwards. When the RPMs drop to the level you want to shift at slip it out of gear, raise the engine up 500 RPMs and then slip it into the next lower gear.
On a 13 speed, lower five gears the same as a 10 speed, then there are 300 RPM difference between the upper 8 gears.
Use of the clutch is optional, but if you use it, you will need to double clutch.
