MazdaSpeed6 1-2 Shift Shock

[Karma_hunden]

Thanks everyone for the feedback.

Thanks Karma_hunden, I send you a PM asking for some more details...




I noticed that too, when I shift below 2500rpm, the car does it relatively smoothly, but when i shift between 2500-3200rpm, the car get's very jerky... But isn't there some disadvantage to shifting out so early? Short-shifting or something?

Also, when I shift out early, the gap between the car in front of me and my car becomes very great, I never had this problem on my automatic car, becuase I would just press the gas and keep the gap a car's length. But now when I'm trying to shift out early to avoid shift-shock, i create a big gap. But if I shift out at 3200rpm or so, i have shift-shock but a smaller gap. So i'm trying to get the best of both worlds. But it's more important for me to get rid of the jerkiness in the ride.



Isn't that similar to flatlining? Or do you mean, push in the clutch -> push in the gas -> switch gears -> let out the clutch?

Thanks again to all for the help you've given so far.

I wouldnt recommend shifting under 3k between 1st and 3rd gear....after that you can shift from 2.4k and up...the reason to this is because you will be putting more strain in the next gear that is not 'quite' ready to pull your car at the speed you are going...this will make the ECU send a bit more of fuel to the engine (chances of less fuel burning increase, and when fuel doesnt burn right, it becomes a problem...and if you want your car to perform right/fast...well you get the drift) to compensate for the torque loss and the one its trying to acquire. Now, the Speed has a lot of torque (+ AWD), and its able to pull this off quite often without any problems, but it is not a good idea IMO.

Yes, sort of. He means that instead of: accelerate -> let go of gas -> shift -> let out clutch...he means: accelerate -> shift (gas no longer being applied) -> let out clutch...if you keep applying gas as you are shifting, then it is considered powershifting

IMO, this is not bad as long as it is done under 3.5k rpms, but I would recommend letting of the gas a bit the moment you are pushing in the clutch if you are going to do it.

I would still go for the way I said to apply a bit of gas as you retrieve the clutch after engagement slowly.

Also, you have to be patient with the Speed's clutch, if you want to go fast, then shift at a higher rpm, but the shifting[time] must remain always the same; unless you are racing....the error most people do is that, they want to go fast[er] and instead of shifting at 4k-4.5k normally, they try to shift fast at 3k...
EDIT: Reving must be consistantly the same in every shift...dont floor it or step on it if you are going to shift at 3k-4k...

Thanks, I make that mistake myself, and haven't noticed it until you brought it up now...

I will try out the suggestions given to me, and post back (probably on Monday). Thanks again for all the help.

I just ease the clutch out a little slower between 1st and 2nd and give it some gas to keep to the RPM's from dropping way off. Nice and Easy. You jsut have to keep the RPMS where the you think 2nd will be at the speed your at. Probably only a few hundred below where you took it out of 1st.

Yaaaa. thats the same thing i do too afroman!! b4 i relized this i was havin the same prob. with the shock. but now i dont have any probs. from 1st to 2nd!!

The CP-E rear engine mounts produced very little additional (hardly noticeable) vibration after installation for me. You mentioned this is your first manual shift auto, practice makes perfect, you'll get better at this soon.

Exactly.(first)

Thanks to all for the advice.
I tried out the suggestions many of you have given, and giving it a little bit of gas white switching from 1rst to 2nd, does get rid of the shift shock for me (usually, sometimes I give it too little and sometimes too much).

Like a few of you said - practice makes perfect, and I'll definetly be practicing.

I really appreciate all the help from all of you, thanks!!!

I think most awd cars have this problem in the 1-2 shift. The evo, wrx, and sti does as far I can remember. But don't quote me on that.

+1 the evo is a bear

start off in 2nd gear and you won't have that problem at all... j/k

i agree with everyone else's advice, just don't let off the gas as much between 1st and 2nd. and make sure you practice, practice, practice. just drive the car, you'll get used to it eventually
