Not quite sure on this model, but it has to be very low on the case, or on the very bottom. The plug will probably use a 3/8" square drive wrench for removal. Never remove any drain plug until you find out if you can remove the fill plug first!
no.... Pontiac changed to a new transmission in 2000
You'll have to pull the transmission pan, and drain the fluid. This is a messy job. I recommend having it done at the shop if you can.
take out the engine speed sensor in the transmission or transfer case depending if its manual or automatic
Assuming that the 5 speed manual transaxle on a 2000 Sunfire is the same type used in a 1995 Sunfire, which uses an Isuzu 5-speed transaxle, the following is the part number specified in the service manual: Synchromesh transaxle fluid GM P/N 12345349. The service manual also says that an equivalent lubricant can be used. Hope this helps.
Remove the transmission oil pan
as far as i know you cant check the transmission fluid on a 2000 Pontiac sunfire. It uses dexcool automatic transmission fluid and very rarley needs to be changed, i have a manual shift and it never has to be changed. Actually the only way that you can change it is by having it flushed the same way you flush a radiator, it has to be sucked out by a machine.
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)
Look at the lower or rear of radiator
The amount of transmission fluid that is needed by a 2000 Sunfire 2.2 automatic varies, depending on what you need your car for. Generally, it will only take 3 ounces.
Look in the owner's manual on pages 124-125 It has a picture highlighting the drain plug in red. It's kind of hard to describe exactly where it is.
