AM I the only one who gets their car like jerking once they downshift nomatter what the speed?

for ex., if in 4th...and go to third, the only way the car won't jerk is if i am going so slow in forth that the RPM in 3rd would be at 2000 if in that gear, thus meaning, I'd be going roughly below 2000 RPM in 4th at the time.

DO you guys get any shaking or jerking?

cuz i know if i in 4th...downshift and try to redline, the car will jerk real bad but will still run.

rev match. search around for topics like "heel-toe" "double clutch". it'll explain what you're experiencing. lots of threads around here that'll talk about it. although they might not say anything about jerking cars when downshifting, it's the solution to what you're feeling when you downshift.

Try easing off the clutch pedal when you find a gear.

If you're fully releasing the clutch immediately after shifting, it's going to protest.
