gear shifting problem
 

hey guys, i have a 1988 toyota supra 3l manual, iv had it for 6 months and now have encounted a problem, the other day when driving i found it hard to change into 3rd gear and the same into 4th! i changed the clutch cylinder on the side of the gearbow (cant remember if its the master or slave) 5 months ago because of a leak. the car drives fine now, i pumped the chutch for a few minutes yesterday because i thourght it could of possibly been an airlock (as i top the fluid up every 6 or so weeks). Could that be the problem or is it likely to be something else?

check the master cylinder....if its wet at the firewall...if not also check under the carpet where the clutch pedal is..if its wet it means it's bad too..
