manual transmission issues.
 
Hey everyone.

All you manual guys, when you are stationary with car running are you able to put the clutch in and select every gear with ease not grinding or effort?

I've noticed for ages now (since I've had the car) that when I do this 4th and 6th always hard to select.

I've also started to notice if I go for a 20 min drive stop the car turn it off leave for 5-10 mins and drive the car again I have no issue.
Although If I just drive the car for hours the issue still occurs.
Can this be explained at all?

I find that mine goes into 4th almost intuitively. Going from 5th to 6th does take a bit more effort to not let it slide into 4th. I don't notice the on/off difference you're describing.

Cjymiller 05-10-2013 06:15 PM

No issues here. I can select all gears w. ease.

Rayme 05-10-2013 06:30 PM

How is this an issue? You get up and go from 4th or 6th gear on occasion ? Lol

Narcoden 05-10-2013 06:34 PM

Mines a tad finicky going into 1st if I'm not almost completely stopped. Doesn't really bother me though. All other gears are smooth as butter.

I've had many MT cars over the years... Sometimes a gear can be a little harder to grab than others.

Conmon things with Our cara when the tranny oil is cold ive noticed.

Issue cause it shouldn't happen ...

Yeah I also have the issue most ppl have as well going into 2nd.

1st through 3rd have more syncros than 4th through 6th, the issue is because the gear isn't perfectly lined up when you're trying to select it and without the syncros spinning they aren't very effective at lining up the gears.

If you put it in neutral, let out the clutch, give it a rev, push the clutch in and try to select a gear it should go in much easier.

works as easy as a common car..no issue

Why it shouldn't happen? You're trying to synchronise gears while the car is not moving. And long as it doesnt grind there isn't an issue here with the gearbox. If it did grind, something would be wrong with the clutch. Transmission needs movement to work properly. What you are experiencing is the same reason some car won't go in reverse the first time around, when that happens just a kick of the clutch and trying again will make it work because you just made the input shaft rotate again and gave it another change to properly engage gear.

It's a bit hard to visualize, I know...but it's the same reason you can't shift a motorcycle's dogbox more than once while not moving without rocking it back and forth, and the same reason a bicycle's derailleur won't change cog without motion :) I'm over symplifying it but the fact is, changing gears is done best when things are moving.

What if you just clutch in - put it in neautral - rev - select next gear - clutch out?

wparsons 05-11-2013 01:54 PM

Clutch has to be out in neutral to get the intermediate shaft spinning when you're at rest.

If you're driving (not stopped), then unless you shift REALLY slow the intermediate shaft will still be spinning, and unless you stop the output shaft will be spinning.

My whole post was directed at the original question which involves the car being stopped while doing this. The issue while stopped is that one (or more) of the shafts need to be spinning for the syncros to work and line up the gears.

StormTrooper 05-11-2013 03:34 PM

I don't see the first and second gear as an issue... All manuals that I've driven are stiffer when cold.

What does bother me is that going from 4th down to third is smooth while going from second up to third is not. ( second to third feels like wrx tranny) the rest feel Toyota /vw/BMW

DriftEightSix 05-14-2013 04:44 AM

Guess what!!!

So I had it at the dealer yesterday and today.

to get the popping sound fixed; I got them to look at the tranny issue.

They changed the oil; AND!! I can be stopped and go through all gears without an issue!!!!!!!!!!

My transmission has improved as I've put miles on the car. I'm at about 6000 miles and the transmission is as smooth as most cars I've owned except for my Hondas. For normal highway driving, I frequently skip gears; going from 3rd to 6th when I'm accelerating to 55 mph traffic. The 6th to 3rd down shift is also nicely spaced when braking for a tight corner. After all, 3rd is good for nearly 80 mph and the lower gear offers a lot of flexibility in controlling entering speed and exit speed.

Marcoscrdo 05-14-2013 11:23 AM

Only problems i have is if im trying to accelerate between gears sometimes at high speed seems like the gear shifting gets "stuck" and force needs to be put into it. Is that normal?

wparsons 05-14-2013 05:01 PM

High vehicle speeds, or really fast shifts?

usptwins 05-14-2013 05:35 PM

Accelerate between gears?

Eurasianman 06-07-2013 01:38 PM

Anyone experience an issue where you go WOT in 3rd or 4th gear and then shift into 6th gear? The issue being that when you try to go into 6th gear, it grinds a bit. In my previous vehicles, I do not ever recall having an issue skipping gears and hearing it grind at the same time. I know part of the solution is to not skip gears, but I was just curious as to if anyone else had had this issue.

Yes. Top of 3rd to 6th will grind almost nearly every time for me. I just stopped doing it.

StormTrooper 06-08-2013 01:29 PM

Only happens to me if you shift it fast...if your skipping you're not in a hurry to be in 6th so just slow shift.

Anyone else have my issue with 3rd? The gate seems odd compared to the other gears on upshift but not downshift

This was/is discussed in another thread, and the concensus was that skip shifting is hard on the syncros because of the speed differential between the input and output shafts. The transmission is designed to go 1-2-3-4-5-6. however, in saying that you can try keeping your foot on the clutch while shifting to 5th than 6th before releasing as this will help match the speeds of the shafts so that there less force thus wear and tear on 6th. Hope this helps.

Yea.... I try to remind myself just shift into 4th, 5th, and 6th. But sometimes, it's just a bit obnoxious :(

I hear ya, I do the same, but I was only suggesting that instead of releasing the clutch between each gear, just row the gears with the clutch in until you get to the gear you want, bump the rpm and release the clutch. Voila, skip shifting without the harm to your syncros.

Yea, I do that every now and then as well. Just tedious :( I just need to quit flooring it in 2nd and 3rd :lol:
