Difficulty in engaging other gears could be worn
synchronizers as well, or transmission...
Some answers correctly identified wear of
synchronizers as a possible concern on manual transmission cars, but then they offered double - declutching as a solution.
Not exact matches
Exposure to bright daylight serves
as the major
synchronizer of your master clock — a group of cells in your brain called the suprachiasmatic nuclei (SCN).
When shifting down due to other reasons such
as needing acceleration when you have low RPMs, execute the double - declutching procedure to save the
synchronizers from extra wear.
When you are down shifting you are using the engine
as a brake, however if you are down - shifting at very high RPM and your engine is revving, over time the
synchronizer can be damaged, or it is already damaged.
As a means of increasing shift comfort, the manual gearbox uses innovative new carbon friction linings in its
synchronizer rings.
Notes: This product is not designed for use in most manual transmissions or tranaxles with
synchronizers,
as extreme slipperiness may cause shifting problems.
Note: Redline 75W85 is extremely slippery, and
as a result is not recommended for manual transmissions with
synchronizers.
And
as in the previous car, rowing through gearbox takes more effort than any car that comes to memory — 22 percent shortened throws and extra robust steel
synchronizers will do that to a transmission.
The new transmission uses multi-cone
synchronizer rings on all gears for smoother shifting and a more positive shift feel
as well
as for improved durability.
