this was a necessity for truckies back in the day when their gboxes synchronizers weren't as 'efficient' as passenger vehicles...

but yeh, when u go around a corner for example, and u've gone from 3rd or 4th down to 2nd on the way out...rev matching helps a lot with getting a smooth exit, specially for us FWDers...

if i was driving on a straight road and want to downshift
can i just blip the throttle, to match the rev??
instead of like heel, toe and gota use the brake as well

---

Yeah, you could clutch in and blip but whats the point? Why use your transmission to slow you down when you have breaks.

engine brake is a beautiful thing brother...

dont shift back to reverse while moving forward?

Heel toe is ONLY for braking and downshifing at the same time. If all you wanted was to downshift for more acceleration, then you would just blip the throttle to rev match.

That's not rev matching though. What truckies needed to do was double clutch.

yea but they'd rev match in the process to stop the truck from shuddering

so why is it when i drive some manual cars, some cars i drive so smoothly and some so jerky. hopefully im not getting too off topic. also when u reverse, does it shuddeR? and why so? how can u make it not shudder and not ride the clutch

Rev match double clutching. Pretty much the same thing as rev matching except with a double clutch. Some truckies still do it.

It shouldn't if you are doing it correctly. Its all about having the feel for the clutch.

question, are there any adverse affects from shifting to neutral without the clutch?
sometimes i take a little pressure off the gas, and a little pressure on the gear stick and it just slides into neutral, and then i clutch in to gear up.

yeah i use to somestime drive without the clutch
but yeah as the revs drop you can slide it in gear or back to neutral
