School a noob on Trannys
« on: April 16, 2014, 02:03:21 PM »
Once you stop laughing at the title, there is a serious question...

On my mr2, the gears were always very notch;  more so than an 06 WRX with factory short throw and factor fluid.    1st --> second always had to be done very slow unless the RPMs were > 3k,  otherwise it would grind.   My car came without a shift knob and It always had the Subaru momo shift knob on it.

A few weeks ago I got my Subaru 5-speed STi knob back from my brother and installed that to see how I light the heavier weight of it since I always like it on my WRX.   Well Its remarkable how much smoother it shifts gears now just from having a heavier knob.  A heavier knob should translate to more force inside the transmission during shifts, but I am still baffled on the amount of difference it made.

FYI,  I used both the momo and the STi knob on my 06 WRX and while it was better, I don't recall it being this much better.  The STi knob won't melt your flesh either in the summer!   Would any of your intellectual know the real reason,  or is it just the extra force?

The weight makes it easier to shift... try changing the fluid too

The extra mass adds momentum to your shifts, and dampens the vibrations from the transmission.  I have 3 different shift knobs that I rotate on the subaru throughout the summer, and the heaviest has the smoothest shift.  If I rest a finger on it while driving, I can't feel much vibration.  When i switch to a much lighter one, you can feel every vibration, and every gear change requires a lot more effort from me.

Cool,  thanks.   I plan on changing the fluid soon again when I replace an axle.  I changed it a couple years back, but I wouldn't be shocked if it was a long time before then that it was replaced.
