Another question on a 2000
Adding fluid is easy, you only need a long, clean funnel to insert into the dipstick tube. You check it when the engine has been warmed up and the car has been driven a few miles, check it on a level surface, engine running. Changing is a little more involved, and can be messy-you remove the pan, bolt by bolt, working around the bottom until it starts to drip, then pour fron the trans. It is a lot of fluid (about 6 quarts) so you need a large and wide drain pan to catch the trans fluid and rags to mop up what misses the pan. Remove the pan, and pull down the filter, it is just press fitted into the valve body. Use a lintless rag to clean up the bottom of the valve body, then install a new filter. You normally do not have to install a new pan gasket, but the kit you get with the filter will include one-if your gasket looks at all like it is compromised, replace it. After it is all buttoned up, you fill it with fluid through the dipstick, and if I removed 6 quarts, I add 4, start it up, then add in increments of 1/2 quart until it is within the hatch marks on the dipstick. It is not a difficult job, but it is messy and time consuming.
