@Hundl So thats not what I mean. FCLUTCHCHANGERATESCALEUPSHIFT/DOWNSHIFT are the clutch engagement times, meaning it changes the time between when the engine is providing power to the transmission and when it is disengaged. I'm looking for longer gears not longer times with no power.

Is there a way to fix the gear shifting time? For example, when you leave the handling line vanilla the gears are more drawn out, but if you change anything on the powertrain side it shifts from 1st gear to final gear in 1.2 seconds.
