transmission filler and drainer plug seals
I am about to attempt my first transmission fluid change. The workshop manual recommends the replacement of both the filler and drainer plug seals. Are these two seals the same? Does anyone have part numbers?

Part number for the sealing ring is 900 123 011 030, and both filler and drain plug uses the same sealing ring.
Interestingly enough I didn't find a sealing ring on the filler plug when I changed my gear oil the first time, but I installed when I installed the plug.

I only had one crush washer as well. Must have come from the factory that way as my car only has 20k miles. I only replaced the one original and replaced the fill plug without one.
Only problem I had was to "break" the plugs. They were REALLY tight, and there is not much space under the car to get leverage.

Yep- same here, fill plug D*MN tight & without crush washer. Like Chris & Robins' DIY sez, do it first (everyone agrees). Put the crush washers on both and torque to proper spec. and you'll be set for next time!

Hi Graham,
Here's a couple of things I did to make the job easier.
1-Get about 6' of that 7/8" outside diameter hose. With the left rear wheel removed you can put it straight in the filler hole. I then ran the end thru the door handle to hold it steady and keep it nice and high so the oil would flow good.
2-Manual said to put in 3.6 liter which is very near 3.8 qt. Where I live the Mobil One gear oil is sold by the quart. Since the car was at an angle I just put in the entire 4 quarts. Then I removed the filler hose and drained exactly 6 oz. I don't know how critical it is to fill the gearcase to the exact spec. but I felt better getting in as close to the recommended amount as possible.

Some more tips:
a) run an extra 1/2 quart of trans fluid through and let it drain out. It seems to help with the flushing.
b) Get a 1/2" drive 10 mm socket if you can. Using a 3/8" drive may not give you enough leverage, and using adaptors loses some power.
c) And since you have a 4wd car, you may want to change the front diff fluid while you're at it. It's really easy, 2 plugs like the trans fluid. 0.8L fill capacity.
