Only the filler plug. You have to remove the cover to drain the oil.
There is an upper filler plug and a bottom drain plug in each differential. R&I (Removal and Installation) the filler plug first then the drain plug until the differential completely empties out. Then reinstall the bottom drain plug and add 90W gear oil which usually comes in a squirt bottle so you can add it into the upper filler plug. You should fill it up until the level is right at the bottom of the threads of the filler hole.
Thereis a tag on the filler plug for the differential. On my 2001 300M the tag ready 80 to90 wt hypoid gear oil only.
Plug on the side of the differential. Location varies depending on the differential but should be easy to spot. If changing oil, you need to remove rear cover to drain (no drain plug), clean, seal and refill until oil begins to come out of the filler hole.
Changing differential fluid is no different from changing engine oil. You just have to make sure that you find the correct drain plug on the bottom and the correct filler tube on top. --Ken On some differentials you have to remove the cover plate to drain.
NOTE: Check the transmission oil with the engine OFF the car on level ground.# Remove the oil filler plug, then check the level and condition of the oil. # The oil level must be up to the filler hole. If it is below the hole, add oil until it runs out, then reinstall the oil filler plug. # If the transmission oil is dirty, remove the drain plug and drain the oil. # Reinstall the drain plug with a new washer, and refill the transmission oil to the proper level. NOTE: The drain plug washer should be replaced at every oil change.
I have a Yamaha 350 big bear, and differential drain plug is on the bottom of the differential. Just remove the plug and let it drain, put the plug back in and fill it back up... i use just regular gear oil
Just fill it up until the oil starts to flow out the filler hole then put the plug back in and your good to go. Be sure to use the right oil as the Posi / limited slip is different and is usually has a tag identifying it on one of the bolts on the cover.
there should be a dip stick on the bottom of your filler plug.
Automatic trans drain plug is on left side of pan(for atf). differential oil drain plug is directly below differential. Manual transmission has only one plug(below differential in center of trans)
yes the tranny oil and diff oil are seperate, typically there is a drain plug and a fill plug located on the diff usually a 3/4" combo wrench will do the trick
Left valve cover, there is a black plug that unscrews 1/4 turn. Pour in your oil, allow time for the oil to collect in the sump, replace the plug. Good to change the o-ring on the filler every 12k miles or so.
