Now, I never hear people talking about manual trans fluid change, so please enlighten me.
What difference does this make, really? Make revs drop faster/slower? Make clutch engagement more uniform? My car currently feels rougher when the car is really warmed up, like after a couple hours of driving. Revs drop slow, clutch pedal stiffer and squeaky, jittery, etc. Transmission is super smooth in the first hour of driving then it slowly gets worse.
Do the options you guys have listed help alleviate this by making the first hour notchy then the rest of it buttery smooth? What's goin on here
Basically it's preventative maintenance. Changing fluid to rid the transmission of metal shavings from break in and wear up to this point.
Changing oil weight will swing the "sweet spot" of butter smooth shifts to the heat range you want. For warmer climates or heavy track use heavier weight (will shift hard till it's warm), or for cooler climates and more mild use the OEM fluid is probably best even if you do drain and replace it from time to time
