Hi I have a Peugeot 308 1.6 ehdi with a six speed manual gearbox and have noticed that when selecting first or sixth gear it does not go in smoothly it can be notchy or clunky this is quite annoying as putting it in all the other gears is fine.could this be a possible gear selector problem or if its a cable can this be adjusted, any advice would be greatly appreciated.
It could be your...
Modern transmissions use synchronizer rings to make manual shifting possible without the need for double declutching.
Each gear has its own synchronizer ring. These rings are subject to wear. If they are in bad condition gear synchronization doesn't work well and you have trouble putting in a certain gear.
You may want to check out your clutch. When do you feel pressure on the clutch pedal? If anything you may have a small leak in your clutch lines or the master cylinder. Mine did this too, where it was hard to get it into 1st gear. Its because my clutch wasn't disengaging all the way. So I filled it up on clutch fluid (brake fluid) and bleed the clutch and it worked fine.
