Shifting an Eaton 10 spd.

Any one know a trick on an Easton 10 speed to get from 6 to 7th. My brother in law is learning and that gets him just about every time. he finally has stopped using the clutch. I hit it with no problem but can't figure out what he is doing wrong. I don't drive it all the time so it occassionally gives me trouble as well.

6 to 7? Are you sure he isn't having trouble with 5 to 6? That's the shift where you start the pattern over so you gotta be quick about it, winding 5th out a little more helps too.

He is learning with no trailer. The back country roads aren't big enough even for the short box trailer.

Beats me then, I never thought 6 to 7 was any harder than any of the other normal upshifts.

When I started out I always had more trouble in the low side and making the split than in the top 5.

I have found that when making difficult shifts with my 9spd that if I hit the clutch while coming out of gear then releasing it when in neutral it will fall into the next gear easier. For me the 8 to 9 is the most difficult and that helps, also the tranny seems to shift better when pulling a load than when empty

I do just the opposite. I ease it out of gear while backing off the throttle and clutch it as it goes into the next gear. Sometimes I do it without the clutch but use it most of the time. I worked for an outfit that the policy was that you WILL use the clutch to shift.

Clutch it out and it should about self align with the 7th gear hole, clutch it in.

I agree that would be the easiest and safest way. You can surely break an Eaton as I've seen more than one of them trashed by less than stellar drivers.

I've always had the same problem. I can switch ranges just fine, it's that over and up that gets me for some reason. I've found when I let the RPM"s drop to an idle and slowly rev till it falls into gear works for me. Then I hop in our work bobtail to pick up trailers for service, an old White. Left and down, over to right and down messes me up sometimes.

I'm just started driving a '05 KW five axle dump with a C13 in front of the Eaton/Fuller 8LL. When I miss a shift it is usually because:

4. I get lazy half way thru the gear change. Happens after lunch.

3. I don't pull or shove the gear shift lever straight thru the gates or striaght into the next gear.

2. I don't put enough pressure on the shift lever when taking it out of gear thereby causing me to be late for the next one.

And the Number One reason is, I get into too big of hurry and rush the shift. Happens mostly when there is another driver looking.

I drove an old Ford 9000LT with a Thirteen Speed Road Ranger in the 80's and found it easier to get used to than this 8 speed. I've been in this truck for about three weeks now and just now feel comfortable shifting without grinding the teeth off the gears. I'm still a little rusty downshifting while slowing down but it is coming back ever so slowly.

When in trouble you can always double clutch it. I do that a lot.

When the truck is empty I have my best luck up shifting at low RPM's say 1300 to 1500 rpm or less depending on traffic. When loaded I run it up almost to the governor. It actually shifts easier at 66,000 lbs than it does empty.

Thanks for the all the info. Will hook him to the trailer if it doesn't get sold and having try that. We have to take it on the highway to move it to a new storage location so i get to try my luck at it again. Since i don't drive it regulary i foget what i learn and get to used to my nv4500 and the duel disk. will try the lower rpm think that makes sense and less tourqe and hp . Especially empyt as it make so much bottom end any way.
