Hey I was just wondering if it is hard on the tranny to short shift a NV5600 6-speed? It is in a 05 Ram 2500. I have heard both way. One says it is ok not to use clutch and the next said it is hard on the synchro's? So for hauling it is nice because you keep it spooled for longer with out the lag. It feels really good like a big rig. Dosent grind just dont want to hurt anything as the replacement cost is alot more than a clutch!

 

You will get varied responses here also. That said, I do it on my 98 with NV4500, and have had no issue in 200k. I do the same on my car and have had no issues has about 150k on it.

 

Short shifting has nothing to do with not using the clutch. But if you want to know what guys think about shifting without the clutch then there's plenty of threads regarding that topic.

 

I dont see how it cant have anything to do with the clutch? The clutch is engaged a lot fewer times in it life span which should lengthen the life of the clutch. Mainly I am worried about the tranny? Tried seaching for threads but nothing for my situation came up.

 

I believe what you are talking about (and Katoom aluded to) is called "slip shifting" or "floating".
This may help.
Here is a short shifter.

 

As I said, "short shifting" has nothing to do with not using the clutch. You're simply asking if its OK to not use the clutch. And sure, maybe, you might extend the life of the clutch some even though most clutch wear occurs during take off, not shifting, but its the life of the syncros which you will reduce by doing this. Then again, I'm not sure what your situation is either since you didn't seem to find any info regarding.....and the topic gear floating has been hashed out plenty.

 

Yeah, you are saving some clutch material but wearing your blocker rings(synchros) a lot faster.....so it is said on numerous posts re: this topic in the past.

Clutch $$$

Blocker ring R/R $$$$$

Your choice.

 

Rule of thumb: if it has syncrhros use the clutch, if its not synchronized no clutch or double clutch.

It is pretty simple. If the transmission has synchronizers, use the clutch. If it does not have syncro's, shift without using the clutch.

 

Ok sweet that is what I have heard that you arent supposed to short shift a synchrnized tranny just wanted to make sure! Guess I have never heard it called gear floating? Searched that topic and it is pretty clear! Yep a clutch is alot cheaper and easier than a tranny rebuild!! Thanks

 

Its called floating because you have to "float" the RPM's in the range where there is no pressure on the gears and the gears are lined up before you shift. Short shifting is simply shifting before all of the power curve is used in a specific gear. Like going from 1st and letting the RPM's rise, shifting to 2nd and letting the RPM's rise, shifting to 3rd and then quickly shifting to 4th before the power curve is used up in 3rd.
