Some answers correctly identified wear
of synchronizers as a possible concern on manual transmission cars, but then they offered double - declutching as a solution.
Double - clutching will, if done properly, eliminate any additional wear
of the synchronizers and if the engine is running at just the right speed before you engage the clutch after the downshift, the clutch will not have to drag the engine up to speed.

If there is a speed difference between the sleeve, synchroniser hub and gear, the sleeve is blocked by a «blocker ring» to prevent further travel
of the sleeve, the
synchronizer ring creates friction to help match gear speeds.
The
synchronizers have a wear material on them and can be shaped like a cone and once the speeds
of the shafts match (through the gear ratio), then the output shaft is connected to the gear and everything is spinning and power can be applied by releasing the clutch pedal.
There are three components
of wear I will consider: shift linkage, gear
synchronizers, and clutch throwout bearing.
When you press the shifter to place the car into gear, the
synchronizers in your transmission connect one
of the pairs
of gears to the output shaft.
the grinding sound you hear is that collar colliding with the end
of the gear.the
synchronizer ring keeps things quiet and smooth in between shifts.
The box utilizes double - cone
synchronizers on each
of the six cogs to ensure a reduction in engagement force and smooth operation in situations.

As a means
of increasing shift comfort, the manual gearbox uses innovative new carbon friction linings in its
synchronizer rings.
There are three separate shift fork shafts, which hold three shift forks to activate the
synchronizer rings for the two gearsets on each
of the three gear shafts.
The most common reason a manual transmission would jump out
of gear is due to low or contaminated fluid, worn
synchronizers inside the transmission, or improperly adjusted shift linkage.
Shift effort has been reduced with the use
of dual - cone
synchronizers on second and third gears.
The 10th - generation Civic 6 - speed manual transmission has been carefully engineered to deliver state -
of - the - art performance and shift action, with reduced internal friction, tighter internal tolerances and improved
synchronizers.
The transmission's shift linkage operates smoothly, with minimal effort, thanks to the use
of shortened
synchronizer sleeves and a redesigned reverse - gear mechanism.
The GKN All - Wheel Drive System includes a GKN power transfer unit (PTU), linked to the transmission's final drive differential, containing a
synchronizer and brake to disconnect the all - wheel drive system upstream
of the PTU hypoid gears.
The portfolio
of products includes manual transmissions, dual clutch transmissions, hybrid and EV powertrains, gears, shafts, clutches,
synchronizers, mechatronic systems, transmission control units, and control software.
Triple - cone
synchronizers for first, second and third gears and a double - cone
synchronizer for fourth gear optimize the amount
of strength required to make shifts and establish the right balance between a short, responsive stroke and pleasing feel to gearshift operation.
The
synchronizer rings are a poor design and cause a lot
of grinding shifts.
What the new
synchronizers may do is help the transmission live longer at the hands
of ham - fisted owners.
