Usually I remove parking brake and hold my brake pedal, I build the Revs before pressing clutch and change gear to 1 while I still have my brake on then release gently the brakes while you accelerate. (YES CLUTCHING AND BRAKING AND ACCELERATING in a 1-2 seconds, with 2 feet) I have success 3/5.. so hard to get it right.
..to holding clutch and gas while changing gears? I know the truck won't accelerate while the clutch is being held down, but is there any negative to letting go of acceleration during this process? Say, I'm on the highway and I decide to change gear, I don't see any negatives to just not letting go of throttle, then holding down the clutch, changing gears, letting go of the clutch all while l88Gw.
