Hey guys, just wondering if anyone else has encountered this or if I should make my first trip to the dealer...

When the engine is cold (not up to temp) it seems the shifting from 1st to 2nd is really "rough". In other words, it requires some fenegaling/more effort compared to when the engine is up to temp and the car has been driving for 10-15 mins...at which point I could probably shift using my pinky finger.

Any others experiencing this? My car has just over 6000kms on it.

I've got just over 10'000 Km and I have the same problem. But if you try double clutching it usually makes the shift a little easier until the transmission has reached oper. Temp.

I have noticed the same thing but it's only once or twice if that. Also the same thing sometimes happens for me trying to put it in first gear.. sometimes not so smooth...

maybe its because when its cold the fluid is thicker and the cdv isnt working as it should because the fluid is thicker. get the cdv out and it should be fine

Ok, so it sounds like others have this same issue. I think I may try changing out the tranny fluid for some Royal Purple. I did this in my old mazda and it made a considerable difference in the shifting.

could easily just be the cdv restricting the fluid flow when its cold and thicker till it warms up some. but do as you want

Same issue but as you all say when it warms up, hmmmm maybe I should remove the cdv as recommended, especially if it fixes this issue.

Mine is rough for the first shift into first and into second. After that its smooth shifting. My friend's mustang does it too. It's just cold I believe.

This may soundma little silly, but what is the CDV?

It's a valve in the clutch fluid circuit that prevents the clutch from being engaged too quickly, preventing driveline shock. The CDV doesn't produce the type of shifting issues he's experiencing. It's caused by cold, thick transmission fluid.

I changed my transmission over to Redline MT-90 and it got a lot better.

cdv = clutch delay valve. i agree that its because its cold but i bet the cdv isnt hweling with anything as the fluid is cold and thicker.

Would the dealer know if the CDV is missing if you take it out? Cuz I rly want to do this but if I go in for service then I don't want them to give me a hard time about me removing it..what do u do with it when it's out?

I'd say replacing the tranny fluid with something else is a safer bet then removing the CDV. It's worth a try. I'll report back once I do so.

Yea that's probably a better way to go but if there is no reason to NOT take out the CDV then I wanta do that? Is it hard to do?

on the 2.0 it wasn't hard at all, can't speak for the 2.4 though, I think it's been said that the slave cylinder is internal on the 2.4 (in the bell housing) so that would be a pain in the ass
but with the 2.0 there's no way they are gonna know it was out unless they take the slave cylinder out and take it apart, as long as you put everything back like it should be and bleed the clutch thoroughly they shouldn't have cause to.
the fluid change should DEFINITELY help a lot though, I'm definitely going to synthetic whenever I have the spare time
