Start with the simple and check your clutch fluid level, a low fluid would cause this type of problem and would indicate ether you have a slow leak in the system or your clutch is worn and needs to be replaced soon. If it's your clutch that needs to be replaced soon, take note that you can have your fly wheel resurfaced rather then replace is if it's not past the wear point of no return. Also it would not hurt to replace your transmission fluid and inspect the condition or the fluid and see if there ate any excessive metal shavings in with the oil.

Good luck and keep us all posted on your trany problem and hope it's a simple fluid leak that is a simple fix.

You'll find the drain and fill plugs on the side of the transmission.

Wish my standard transmission didn't need transmission fluid servicing every so often to keep it running without problems.
