Locate the drain plug for the tranny and drop it like you would for a oil change, Let it drain and replace the plug and fill through the dipstick about 2 quarts. Differential is the sane except for there is a fill plug that has to be loosened before the drain plug both are 10mm allen. remove the fill pluf then remove the drain plug , Let it drain. replace the drain plug and you will have to pump the gear oil back in until it starts to overflow. Replace the fill plug and your done.

No prob. ;) Don't forget to clean the magnet on the drain plug.

Once again! I would NOT just drain the fluid and replace on an older GS. There are over 10 quarts of fluid in the tranny, you're only replacing about 2. GO have it flushed at a reputable shop!!

If the tranny has been maintained properly a drop and fill is all that is needed. Flush and fill ? You might as well do that everytime the service is performed, I don't think so.
