hey i recently purchased a 2000 jetta. it will run in reverse but when i put it in drive the car does not try to move forward. i tried it in all gears but nothing.i'm really not sure about the transmission fluid level. the book showed removing the drain pan plug and add fluid in the fill port unitl it starts dripping out of the drain plug. the engine is a 2.0 gas with a automatic transmission. any help would be great.
