Floating gears

Question:
When i was in school last year,we watched a movie from eaton fuller on their transmissions,they were telling us the benifits of progressive shifting,and other things,I noticed they said that many seasonned drivers float gears,thinking it puts less wear on the clutch,when the tape itself said it was actually harming the transmission more.Until this point,every experienced driver i mention this to,tells me im wrong,or diddn't hear the tape correctly.

Answer:

and in some rare circumstances (like getting going uphill with a heavy load) you could harm the transmission while floating gears. If you do not time the float just right you basically force the tranny into the next gear and eventually if you do it enough you can cause some serious damage.
However as far as I know a good proper float will not harm the tranny at all.
Only two things I know of are infinite. The universe and human stupidity, and I am not real sure about the universe.

Answer:

I've seen those tapes a couple times and they DO almost beg drivers not to float their transmissions.
But what else can they say? It's "ok to float our transmissions...they can take it if you screw-up!"...?
You can shread the drive train by mis-jamming a clutchless shift and sending a big shock-wave beyond the components' breaking point, so they have this disclaimer.
Play with floating gears on open interstates when it's safe to do so. Real gentle, cause if you jam it in too fast on changing rpms, you can strip those light-weight Eaton Fullers, or any transmission.
Double-clutch all aggressive shifting.
Save the floating for more relaxed, gentle changes in speed.

Answer:

NEWBIES...
Please be advised that it is a firing offense at many carriers if caught changing gears without the benefit of the clutch (especially after driveline damage-and it is not that hard to figure out why it happened). Do it if you like...but just be aware of the ramifications.

Answer:

I take a lot of drivers on road tests, new and experienced.I always tell them, that in my judgement it doesn't matter if they clutch or float the gears. Either one, if you do it properly you are treating the drive train well. Either one if you do it wrong, you are harming the transmission. I see many who float the gears and barley scratch a gear, when many who use the clutch force it into gear and you can almost hear the teeth fall into the bottom of the transmission. Advise and opinions come from all sides of the industry. This is just mine.

Answer:

svdanny,
...and a good opinion at that, coming from a tester. Wish you'd jump in with your opinion more often! It may ruffle a few feathers, given the diversity of opinion here but it always gets folks thinking, and everyone ends-up coming away with a greater undrstanding of what others think, drive, test, etc.... That's a good thing.

Answer:

Bedspread has some good advice. I would also note that on state test as well as many company test you are required to double clutch.
I almost always float but it isn't always good on the tranny. Even on a flat smooth road you can jam the gears and cause exsessive wear.

Answer:

If you don't know what your doing you could cause server harm to the tranny. As for a newbie I would continue to practice double clutching.
I worked with a guy once that said he knew how to float the gears, well one morning he asks me to ride over to the local Mickey D's. Well let me say, every shift he made, made cold chills run up my spine. I'm just glad that I never had to drive his car.

Answer:

You Know I saw guys and gals at the Driving School that I went thru,That had no idea about double clutching or Floating.
Some Graduated Still Grinding Gears while Double Clutching.
And Yes I have seen the Eaton Fuller Video,They Expressly say that Floating Gears Does Damage to they're Transmissions.
Im Kinda Like Shuffler,To me its Whatever You Feel Comfortable with.
The Other thing is, Why In The World Would they put A Clutch in the 1st Place If they didn't want you Using It.
Go figure they are the Ones that make it,You would think they know Best.
And Yes I Prefer to Float Gears Myself, my just ,My personal Preference.


Answer:

And Yes I have seen the Eaton Fuller Video,They Expressly say that Floating Gears Does Damage to they're Transmissions.
Yes, it does damage to the trans and complete driveline, but I am not wanting to start that old argument. If a carrier allows it's equipment to be abused in such a manner...that is their decision.
This is similiar to what an old timer told me one day about a car with two sticks. If GOD wanted those two sticks moved at the same time, he would have given you two right arms...

It's tough getting started and stopping without one.

Not really. I lost a clutch in Roanoke late one night and took it into the yard in Winston-Salem without a clutch (not on a tow hook either).

Answer:

Last car I owned (FORD CLT9000) had over 600,000 miles on her when I sold her.
Cat engine had 500,000 because she blew at 100,000. Warranty put a NEW Cat back under the cab. (Guy that bought her added another 300,000 before he sold the car)
13 speed transmission wasn’t touched!
Clutch was original (Clutch brake was replaced once)
Clutch springs broke 6 months after I sold her.
Rearends were not touched.
Brakes were original (I believed in slowing down before I get there) Did have an engine brake, however back then 3406B was a tad weak in the Jake Brake mode.
Did I use the clutch?
To get her rolling from a stop!
Sometimes when going up or down a hill. Other times if I missed a gear. Most of the time didn’t notice if I used the clutch or not! After years of driving, you just do what’s right without even thinking about it!!
Never lost a clutch or drive train since I was 19. At 19 I (a green-horn) downshifted from 2nd to 1st while hauling a large load of coal out of a deep pit and ripped out the power divider! (Dumb)
It was exciting…
Brakes couldn’t hold her and I rolled backwards down into the pit and stopped just 4 feet before hitting the loader! Driver standing halfway up the hill said I had really big eyes when I roll backwards!

Well BEDSPREAD.....just hope there weren't any stop signs going-up hill!...
You still swearing on a stack of bibles you "never once rolled through a stop sign at 1mph" in your your many, many, many, many, many (etc) years as a CMV driver?

Yep!
