When I change the gear to 2nd or 3rd, there are so kind of funny sound and not that smooth, does anyone got this problem as well??

 

hmmm, i dont hear a thing when i shift gears...oh wait, thats cuz i dont have my car yet, dangit!

i'll let you know when i get it by the end of the week - i hope that aint a problem tho

 

At first, I kept getting caught up in between the gates from 2nd - 3rd, because I was trying to go up, over, up. I have to make a straight, diagonal shot from 2nd to 3rd, and it is smooth as butter. See if that helps...

 

I had the same problem as B-Nez described, but seem to have gotten past it. I haven't noticed any other problems.

Luv the car.:D

 

alright
let me have a go again
thanks

 

how do you change the gear from 1st to 2nd?
I still don't get it smooth.

 

i find that to get that shift really smooth you really need to time it so the shift takes a full second, shift too fast and you get the klunk + a lil bit of rodeo action...which for me is usually 4200->3000rpm however, it's more so shifting from 9000-> 6000 rpm because you gotta wait that much longer for the motor&layshaft to spin down...assuming you dbl clutch.

 

double clutch?? Why? i thought the tranny came with double/triple synchros?

 

well, in my particular case, it's really just a force of habit, haven't tried shifting normally yet. hard habit to break when you've been doin it for years =p

 

Well it seems like this problem runs in the family.

Use to drive the miata, have problem going into 2nd gear especially during hard driving. It is quite frustrating when you're trying to get some fun.

Many people have that same problem with their miata and were discussed at the miata forum.

 

I have the same problem with my '89 Taurus SHO. Seemed irrelevant until I remembered that it uses a Mazda truck transmission. It is not so much that anything is wrong, just that it is an old POS cable setup.

 

Lightened flywheel. This will let the engine change speeds faster, letting you do fast 1 to 2 shift with less head (your skull) toss.

Or it could be emissions control systems leaving the throttle open, keeping the engine speed up.

Like someone mentioned, it might be just practice. How quickly you're getting off the throttle, at what point are you engaging the clutch, how quickly you dis-engage and your throttle position at dis-engagement. You might burn your clutch slightly but try openning up the throttle at disengagement. You won't have and any forward head toss.

In straights where being smooth is less critical, let the clutch out and have a 2nd gear tire chirp. :D

 

Double clutching, gear shifting isn't about how many synchros your gearbox has and doesn't affect how your gearbox runs, besides your cars are very new. And you should give it time for the gearbox to run in properly. Here are some useful hints on how to run-in a new gearbox properly.

Shifting at different points - Don't constantly shift at the same RPM although you're also running in your new engine. That allows the synchros and gearbox to have the chance to rev through the general rev range. You don't need to redline or shift high, just shifting at different RPMs is optimum to help the gearbox run in.

Temperature control - As the weather is cold right now, especially in Sydney. It takes time for the gearbox to heat up, you'd find that shifting at cold temperatures is notchy (not-smooth) but once it heats up, it gradually improves. Being that the gearbox is also new, that takes a longer process.

If all else fails to improve the shifting/gear changing feel, look at changing your transmission fluid later on - Ala 5000KMs at least, and go full synthetic. Brands like Motul and Redline make very good transmission fluid that will dramatically improve your shifting. But remember, you need time for the gearbox to run in and that's probably the most essential step/consideration right now.
