Sometimes when the car is not moving at all the synchro splines may not
align well enough to allow you to just push them into engagement. This
condition is aggravated when the transmission lubricant is cold. When this
happens it's best to return the shift lever to the neutral position; let out
the clutch for a second; and then depress the clutch and quickly but gently
try engaging the gear again. The quickly is because you want to engage the
gears while they are still spinning and they will stop if you wait too long
especially if the lubricant is cold. You should never let out the clutch
while you are trying to force the shift lever into gear. This will damage
the alignment ramps on the synchros and will shorten the life of your
transmission significantly.
There is another possible cause for the difficulty you mention. Sometimes
the clutch plate tends to get stuck on the splined shaft so that it still
drags a little on the flywheel even though you have depressed the clutch.
Then the transmission synchros will present a large resistance to being put
in gear because the gears are still moving relative to each other.
This is most likely to happen after the car has been sitting for a while in
humid conditions. The best thing to do is to turn off the engine; put the
transmission in gear while the engine is stopped; depress the clutch and
restart the engine. This should break the clutch disc loose and solve the
problem until the next time the car is left sitting for an extended period.
Of course it's possible that your transmission is failing but I wouldn't be
too quick to decide that. It always takes a little while to get to know any
"new" car.
