get a manual for your car at your local parts store. most man. trans. need to be checked by removing a plug from the side of the trans. case (under the car) if grease runs out it is full, if not add some. BUT you will need to know which kind to use . i have found it a lot easier to take my vehicle to a quick lube store for a complete oil & lube job. it's a good idea to check your maintenence schedule for when to change fluids in engine, trans, radiator etc. etc. your manual will give you all this info. always make sure your veh. is on as close to level ground as possible, when checking your fluids, this helps give an accurate reading. unless you are mechanically inclined and know what you are doing. i strongly suggest that you use a lube store, as serious injury can result if you don't know what you're doing!!!!
