Q: It is very difficult to get in to gear and seems to be getting worse, using 1st gear is becoming almost impossible. There is also a very loud grating noise every time I go into reverse. My gear stick goes in easily when my engine is turned off though. Thanks for your help.
A: usually then gear box should last for many many years. the problem starts with the clutch. if you re sure that the is working properly (like you accelerate instantly ) then it might be the gear box . but even in this case you dont need to replace. check on your service book if automatic when was the last time you changed the oil. if manual check for any licks under the car. if nothing of these... the you might need to get a new one. but in your case it is not expensive.
