Also noticed a few drops of oil under the car. Its about the center between the two front seats. The liquid is definately not engine oil - it seems oily though. Checked the brake oil - level is fine. I'll try to get a photo from under the car when I jack up the car for the brakes. Thanks everyone - One project complete ;-).
Hey, lad. Good job, glad you got a big one out of the way.
The leak (given your described location) sounds as though it could be AT fluid. There is a connector that is a known potential issue on the 722 transmission, often it leaks so badly that the fluid runs up the harness into the TCM and ruins it. That's the FIRST place to check.
Take care and enjoy the SMOOTH ride,
Greg

Took a photo. Does it look like the AT Pan gasket may be faulty ? AT Fluid change may be in order. What do you think ? Where is the sensor that everyone talks about from where it leaks ?
Since this issue is not on point for the other thread I made a new one for you, plus this will get it some exposure it would have otherwise missed.
That's certainly a significant leak, probably is the connector but the guys who have suffered through that will chime in to confirm or "disconfirm", as it were. (Bonus points if you recognize the movie line.)
it would be smart for all w210 owners, especially the ones with the earlier years to check the connector that greg is talking about. the part costs like $10 and is super easy to change. when i checked my car it was a little wet, it wasn't bad where the atf went to the tcm, but i'm really glad i caught it early.
if i remember it right is connected to the left wire (passenger side) from the above pic, and you don't need to take the pan off. follow the wire to the pan and i think a little rectangular piece clips off, and take it out. it was a while back so i could be a little off, and also mine is a 1997, and could be a little different from the newer ones since it was the first 722.6 version.
I have quickly put together some of the pictures I took when replacing mine last summer. Please do not take it as a tutorial but rather as a simple illustrative guide. This is a relatively simple job.
If no access to a lift, raise the front on ramps. First step is to remove the side stainless steel shield shown hanging on some the pictures. The electric plug is a two part component. The ivory color piece is a twist off mechanism, rotate it probably 3/4 of a turn or so and remove the electric plug, which will stay hanging from its wire harness. Installation is the reverse.
The red O ring needs to be purchased separately. The last picture shows the piece you have to purchase that does come with its O rings.
I apologize for any omissions and hope it helps.
Cheers

Hey, Franasia.
Thank you for taking the time to put this together, quickly or not. Do you still happen to have the part numbers from your invoice, etc? If so please PM them or post and I'll add them in. I think this is really useful, and a great example of the forum working for everyone.
Denials, disclaimers and apologies aside, I thought this was worthy of inclusion in the DIY thread, and exercising my mini-mod prerogative, it is.

franasia, very nice write up. so you replaced the red o-ring also along with the last piece? when i replaced mine i didn't change the red o-ring, only the connector part that twists off (the last picture from franasia's pdf). next time i change the tranny fluid i will for sure.
was your connector wet with atf? in my case when i twisted the connector off, the part that doesn;t twist off was a little wet (picture 1 from franasia;s pdf). i cleaned it with some electronics cleaner and let it dry/drip for a little bit until i was sure it was dry, then i twisted on the new connector part (last picture from franasia's pdf) and put everything together. and i didn't lose a lot of atf, so didn't need to add more.
by the way the pic shows the location of the connector from the above pic, even though franasia's pictures make it pretty clear where it is.
