How do i adjust my clutch? and it's really hard to change the gear especially reverse.

Could be the clutch.
Reverse and first do not have gears that line up like the others do. So if the clutch is not disengaging all the way, they will grind.

sounds like the cable may need to be tightened

It could be typically due to one or two things:

1) The clutch plate is sticking on the gearbox splines due to build up of corrosion or lack of lubrication. May happen especially after long standing with no operation.

2) Gearbox oil is old and requires replacement.

3) Clutch operation requires adjustment or repair. Check clutch fluid or cable condition and operation.

clutch could be worn out ?
how many miles since it was replaced ?

Hello Hannah, I don't believe just yet that your problem is inside your transmission. I would first check the adjustment and condition of your clutch. If it were an internal transmission problem it would probably be with one gear ,not all of them. You aren't grinding fourth gear because it is possible to shift into fourth gear without using your clutch if your RPM's are high enough. If you are really lucky you will only have to adjust the clutch, and if your not so lucky you may have the go for a new clutch, preasure plate, and throwout bearing. In any case I would like to know how you make out, please contact me and GOOD LUCK.

yes it sounds like the clutch is worn.1st thing when a cutch wears is its hard to get in reverse
as long as all air is bleed out(pedal feels normal)not a bad job unless its 4 wheel drive
good luck

dear friend-you can bleed the clutch.im am sure this will solve you problem

It sounds like it hasn't been setup right, and needs adjusting, there is an allen key bolt on the top of the pedal, try adjusting it here first, if it doesn't cure it then adjusdt it ontop of the gearbox

take it back to clutch repair shop.. linkage is loose-out of adjustment/ clutch is not adjusted/bled or installed proper/ or internal transmission damage has occurred (syncros) .. good luck
