I've got a manual apporaching 10,000 and its 3rd oil change. When I drop into gear the car is starting to jump and shudder.

I haven't had any transmission problems until now. Most owners said the lower gears were bad for the first few hundred miles but I never had a problem.

Also, my moonroof is acting up again... it sounds like its cracking when I open and close it.

Any comments?

 

go to the dealer and explain what is going on. let one of them drive it so they can see for themselves what is going on.
