Default How to make shifting smoother...

I have the factory option short shifter. It feels like crap. The shift is very rough. Whats the smoothest shift, with a nice short throw, and good height available. Do I need a short shifter set and bushings or what do I need. Im clueless with the stuff.

Try a stiffer bushing(kartboy) and STi tranny mount. Thats what I have and it improved the quality of the shift a lot.

another shifter isnt going to affect the "feel" of the shift just the throw and the height, the bushings are whats gonna help and maybe a STi tranny mount, also you might think about getting a shift kit instead of a short shifter so it has all the linkages and every thing.

instead of this:

you would maybe want this:


I hope this helps

Get used to it. The Subaru gearbox just isn't all that smooth, and no shifter is going to make it any better.

i agree especially since your wrx is still brand spanken
new. i had trouble getting into 5th gate when mine was
brand new so did not do the short shifter until after
10k miles. when 5th was no problem, i installed a
kartboy ss along with a greedy weighted knob.

very super nice. and i dont use the bushings
because its already pretty firm as is with just the
shifter.

So 10,000 miles is considered broken in for the tranny?

Hardened bushings will just make the shifting even rougher. That doesn't sound like what you want.

However, I like the feel of the hardened bushings.

Well I found that Silkolene`s Syn 5 helps but I also found that for everyday driving if you pause for just a second while shifting(in the nuetral gate) it`ll give time for the synchros to mesh and the shifting will be much smother.I also have the Kartboy shifter/bushings.

Mike wrote up a good piece on shifting here:

Shifting Tips

I wore out my first transmission on my RX-7 by shifting too quickly for the synchros.

yeah, you haven't quite told us what kinda shifting you like...some like that notchy shift...some like that smooth as butter shift...going w/harden tranny mounts and bushing is only going to make it notchier

if you want something a bit smoother....try a different brand of fluid, that seems to work for some

no more mis-shifts after the kartboy ss and weighted knob.

I have kartboy short shifter and bushings, but it was notchy with the stock knob. So I got a momo knob that has a rubber piece on the inside and it improved the feel dramatically

I have the factory short shifter, and my tranny is as smooth as butter now (10K miles). Still have a slight notch going into first, but it's a lot better than when I first got it. I'm gonna put in some synthetic oil in the gearbox soon... I hear that helps a lot with the smoothness of the shifts.

same here. 400gram knob does the job for me.

quote Mike:

Quote:
The Impreza has a hydraulic clutch with a damper built into it. It has a reasonable, but not high force pressure plate. The flywheel is a standard unit, designed to give smooth starts without the motor stopping. That is to say it has enough mass to make it easy to start off from stand still. These factors give the clutch is operating behavior. Also note the Subaru transmissions are tight when new and need broken in. They will not really feel good until 10000 miles or more, just like a BMW. They are built to tight tolerances so they will drive a long time. The trade off is a tight feel when new.
This quote should be a sticky.

I have heard that the tranny bushing can help with some of the shudder and clunking that you might experience in shifts. Never had the chance to try it first hand though.

Just put another 1000 miles on my car and the shifting is getting smoother. My Technique is pretty good. I think a weighted shift knob would make a big difference but its getting better as it breaks in.

yup, mine just passed 1005 miles mark and it's gotten better. Plus, I'm done with the brake-in period

The "feel" of the shift is dependant on many things. How you shift makes a huge difference. From my experience, the WRX gear box is a bit "notchie" but that gives it a really nice feel. Part of this feel comes from the fact that this is a sports car that allows you to feel the cars reaction to the road, engine and your input.

Similar cars that have this amount of feel include older 911's, most current Ferraris and other high input sports cars. Butter smooth shifting is possible with all of these, but it is achieved through clean shifts made at the appropriate RPMs.

The dull smoothness of other cars like Hondas and Toyotas, is achived through longer shifters, softer bushings, more forgiving clutches and more tolerant transmissions.

The WRX has a traditional sports oriented gear box that is somewhat unforgiving. The notchieness you feel is partly in response to haw you shift. Smooth shifts will be accomplished when you are able to feel when and how to shift in tune with the rpms, road conditions and other inputs.

Harder bushings and a shorter shifter will only increase the input you are feeling.

So, the clutch and gearbox are pretty good and the short shifter reduces the shift through by 27% like it is supposed to, the rest is up to you.

Give it some practice and time and focus on when you are shifting and how you shift. The transmission should be broken in by about 2000 miles.

If the Honda shifters are dull, I would like to have the dullest tranny on the planet. Honda shifters, IMO, outclass the shifters from any other major make by a mile.

Ever feel the S2000 shifter? That is one perfect gearbox...

Yes... the S2000 shift feels very very nice. Especially with a weighted knob
