Choppy shifting
I've had a 2014 BRZ since June of this year. It is a ton of fun to drive! One problem is rough shifting, which I never had in my other cars. It seems that shifting smoothly or choppy-by bumping off the gears before slipping into the next gear-is only a matter of chance, and happens about half of all driving time. Does everyone else have this experience, and has anyone been able to address this successfully, maybe with Subaru? Thanks.

Are you speaking of how you can hear the gears engaging after maybe 1/8 of a second, behind you when it's quiet outside? I personally have an issue shifting from 2nd to 1st. Sometimes it's smooth as butter. other times the shifter just won't go in.

I've swapped fluid to Redline and stiffened up the entire powertrain mounts. Cusco motor mounts, tranny insert, whiteline shift bushing, whiteline diff front bushing and cusco rear diff brace.
All of the above helped. When driving the car hard I noticed that it shifts much better in general and came to the conclusion that our transmissions just like being PUT into place, be assertive and accurate with your shifts and it should help out, don't be gentle. This is also why the heavier shift knobs help because they help shift with more force without changing the speed of your shifting motion. |

When your car is cold, let it idle in neutral for a minute or two. This usually does the trick for me !

Assuming the engine and tranny are warmed up, I find the car very easy to drive smoothly when either going leisirely, or when driving with gusto. It's the in between normal speeds that seem to be a little jerky for me.

In addition to the suggestions above, try leverage. I added a lever extender, paired with a weighted knob and rear shifter bushing. Shifts like butter. Latheworks custom made me mine, but they can also be found here:

It will get better with time, and as fika84 stated being assertive rather then gentle seems to get a much more positive shift while eliminating the bumping off of the next gear like you describe.

When cold, or all the time? Upshifts, downshifts, or both? |
