Up and down button below the shifter
So, I always thought the up and down button below the SMG shifter is to change the speed at which the clutch engages. At least for my car, I had it wrong. It adjust the RPM at which the transmission up shifts. If u have it at low setting, the automatic transmission shift at lower RPM and when I have it high, the transmission doesn't shift until I hit 4 or 5,000 RPM. Just random discovery of the day lol.
By the way, MDM competition traction control is really awesome. For those that like to kick out the rear from time to time without risking losing control, I highly recommend it!!
