Crunchy shifting?????

So when I get in my car and it is cold outside I have noticed that it is harder to shift. It feels crunchy when I go to put it in gear. Once the car warms up it's generally fine, sometimes it still does it. A couple of my friends just said I have to wait for the car to warm up completely and for the tranny fluid to start flowing.......Does anyone know why or if I should worry about this at all?

how long has it been since you have changed your transmission / clutch oil..

sometimes it gets low thats why it crunches or is stiff..i use dot 5.1 performance oil and it usually is like that in the morning for about two mins but thats because it has a higher heating point than most oils.

get ur oil level checked and if its not that then try changing ur oil.
if still no luck then u have tranny / clutch probs!

AFAIK that issue should just be attributed to old trans oil. Though my corolla always had that issue, regardless of if the trans oil was new or not.

not necessarily. My shifting is difficult sometimes in the morning. Its basically the same concept as the engine itself. In the morning, especially when its cold out, all the gear oil takes a little while to heat up to operating temps. So don't be alarmed at notchy shifting...unless its happening ALL the time.

Ok I know you say crunchy, buy that do you mean its makes a grinding sound? Or is it just hard to put into gear?

It just feels crunchy there is no real sounds. It just feels like when I go to put in to gear I have to push through something tough and Idk "crunchy" is how I would describe it. I was planning on changing the tranny fluid the next time I did the oil...just hadn't gotten around to it because it is well freezing here. Does that help at all?

When it's cold the tranny fluid doesnt flow as freely and takes longer for it to work its way into all of the gears after sitting overnight. It happens to me too but only my 1st to 2nd shifts on mornings when it's pretty cold

Yeah my tranny does that everyday going from 4th to 5th gear it has like a crunching sound and its very stiff. Honestly I don't know what caused it I just know that my car has alot of miles 136k and I suppose I need to flush out/change the tranny fluid or if not get it checked. What do you guys think?

yup that seems like the same problem I have I just dont know how to describe it its like a Grrunnnt sound while it being stiff and but except it only happens in 4th to 5th. the only thing is that it happens anytime regardless of the weather or how long I have the car on I mean I drive 30-40 min to work and it still does it soo freakin wierd

I have that also when I'm in a rush and don't let the car warm up like I'm supposed to. I started making sure I let the car warm up completely before leaving and no more crunchiness.

Marcucci over on PreludeOnline disassembled a 5th gen 5 speed to inspect this problem and discovered it was a design flaw. It has something to do with the 5th gear syncro gear. Do you also have a hard time getting it into Reverse? That was another problem attributed to the same design flaw. If you have a hard time getting it into 5th and/or Reverse... BE CAREFUL! Don't EVER force your transmission into gear. If it doesn't want to slide in on it's own accord, try double-clutching (when shifting, disengage and then re-engage the clutch while your shifter is in neutral) on your shift into 5th. As far as having a hard time in reverse, if it doesn't want to go into reverse, sometimes it helps to put the shifter into a forward gear before going back into reverse, and it also helps to sometimes return the shifter to neutral, take your foot off the clutch, and then try all over again. For me, 9 times out of 10 the second time I try to put it into reverse, it happens flawlessly.

This is the thread I was talking about.

doesnt double declutch only work when you have the clutch pressed in for long periods of time..i.e when parking between two cars and you have to keep changing gear to move forwards and backwards????

Double clutching really is only helpful on cars with no syncro rings... (or bad syncro rings). It simply helps to match rotational speed between your engine and rotational speed on the gear you are trying to select. On a properly synchronized transmission, this is completely unnecessary. But... since this problem stems directly from a bad syncro issue, double-clutching may or may not help alleviate the problem, and prolong the life of your 5th gear/reverse.

That happens on all manual transmissions... and it's not a good thing... let your car come to a stop or very close to it before putting it into reverse. Reverse gear is different from your forward gears. It has an extra gear (idler gear) that moves into place between your countershaft and output shaft to make your output shaft reverse its normal rotational direction. If you are trying to put it into reverse while it is still spinning in it's normal forward direction, you are mashing your gears up, and that's what makes the grinding sound. Have some patience and you'll save your transmission some wear and tear. It's also worth noting that your reverse gears are actually part of your countershaft and output shaft... therefore if you damage these excessively, you are also damaging your actual countershaft and/or output shaft. This would make for a VERY costly repair...

This idler gear is also the reason that manual transmisisons "whine" when going in reverse. Forward driven gears are constantly meshed together helical gears, and spin freely of the counter and output shafts when they are not engaged. The reverse gear(s) are spur gears so as to allow the idler gear to slide in between them freely. It would be damn near impossible to slide a helical gear in between two other helical gears.

This following is taken from wikipedia:

Quote:
Reverse is also a pair of gears: one gear on the countershaft and one on the output shaft. However, whereas all the forward gears are always meshed together, there is a gap between the reverse gears. Moreover, they are both attached to their shafts: neither one rotates freely about the shaft. What happens when reverse is selected is that a small gear, called an idler gear or reverse idler, is slid between them. The idler has teeth which mesh with both gears, and thus it couples these gears together and reverses the direction of rotation without changing the gear ratio.

Thus, in other words, when reverse gear is selected, in fact it is actual gear teeth that are being meshed, with no aid from a synchronization mechanism. For this reason, the output shaft must not be rotating when reverse is selected: the car must be stopped. In order that reverse can be selected without grinding even if the input shaft is spinning inertially, there may be a mechanism to stop the input shaft from spinning. The driver brings the vehicle to a stop, and selects reverse. As that selection is made, some mechanism in the transmission stops the input shaft. Both gears are stopped and the idler can be inserted between them. There is a clear description of such a mechanism in the Honda Civic 1996-1998 Service Manual, which refers to it as a "noise reduction system":

"Whenever the clutch pedal is depressed to shift into reverse, the mainshaft continues to rotate because of its inertia. The resulting speed difference between mainshaft and reverse idler gear produces gear noise [grinding]. The reverse gear noise reduction system employs a cam plate which was added to the reverse shift holder. When shifting into reverse, the 5th/reverse shift piece, connected to the shift lever, rotates the cam plate. This causes the 5th synchro set to stop the rotating mainshaft. (13-4)"

A reverse gear implemented this way makes a loud whining sound, which is not heard in the forward gears. The teeth on the forward gears of consumer automobiles are helically cut. When helical gears rotate, their teeth slide together, which results in quiet operation. In spite of all forward gears being always meshed, they do not make a sound that can be easily heard above the engine noise. By contrast, reverse gears are spur gears, meaning that they have straight teeth, in order to allow for the sliding engagement of the idler, which would not be possible with helical gears. The teeth of spur gears clatter together when the gears spin, generating a characteristic whine.

I noticed that it is hard to get it in reverse some times. It doesn't grind it just wont go....I try one of two things when it does that I either put it in another gear like third, neutral for a sec and then try or I just reengage the clutch and try it again. There have been times when I will try like four or five times and it just wont go. Drives me nuts! I did read on here a couple times about the reverse thing so I wasn't to concerned about that. Just the crunchy stuff.

You are definitely doing the right thing .. whatever you do... just don't ever force it into (any) gear. Or you will end up with more serious issues lol. As far as the crunchy gears go... it may be (like was said earlier) just the ammount of time it takes for your transmission oil to warm up, depending on what's acutally in there... You should drain it and replace it with Honda MTF... that's what I did and it seemed to help a bit.

when it doesnt want to go into reverse, just let the clutch out just a smidgen to let it "slide" into gear, works every time
