So I figure it being 80 outside today I would go ahead and work on the truck, wash it wax it and do my regular check over (breaks, fluids, check undercarriage for wet spots) Well to my amazement i found a wet spot.. On my transmission. It was at a weird place too. I hope this is not a serious problem! I honestly have no idea how this happened, and why it would come from where it is coming from. So Noodles! or anyone let me know what you guys thing (10 - Serious, 1 - not to worry!)..

Not that I could answer your question or anything.. I thought I would take a look for myself. Seems mine is exactly the opposite of yours. Don't know what this means, except perhaps I have a minor leak from the rear main seal after 60K miles.
Yours does appear to be on the tranny side, and the rear seal side looks good.

The 2000 430 I had would do that. I'd wipe it off and it would take about 10,000 miles to show up again. It's just a slight leak on the front seal of the transmission. Worry 1 to 10?------1. [8D]

Well with further investigation I found this that my radiator is leaking.. I think the possible fluid might of flung back onto it.

I figure this because i pulled off those black tabs and took a flashlight and peeked around didn’t notice anything suspicious, I shoved my finger in there and it came out clean. !!! THANKS GEORGE !!!

Now to figure out why the radiator is leaking.

Picture 1 -- The torque converter pictures, showing that it is clean inside

Picture two -- The wet spots from the radiator, taken from the driver side-wheel well... It seems to be leaking from the hose that is on the driver side on the very top.

Power steering cooler?
Yup. the hose to that is leaking.. Hopefully the hose is long enough just to snip off the bad part...

Had the same drip on my 99 ML430. Took a while to figure out exactly where it was coming from. A very interesting arrangement at that radiator fitting. If your 'fix' doesn't work, take a close look at the nut that actually tightens into the radiator.

A local shop had seen this leak before and warned me that in trying to tighen it, it could possibly break, necessitating replacing the entire radiator. With that said, I said go for it!

He was able to tighten it maybe a 1/4 turn and since then no leaks...bone dry. hope your fix takes care of it, if not, inveatigate this particular fitting.

Thanks springer - Did you happen to note the type of steering wheel fluid he used? Is it any generic brand or does it have to have the mercedes star on it?

I would stick to the MB stuff. The fluid is a lot cheaper than the damage a mix of fluids can cause to the rack and its seals.
Glad you found the problem. When I first saw this thread my heart sunk, but it looks to be minor, thank god for that.

Hey, I had a leak on the transmission oil cooler connection to the radiator a few years back. Turned out during service or assembly two copper O-ring seals were stuck both on the same side of the screw fitting. Once installed correctly, a copper seal on each side, the leak stopped. [:D]

For the power steering fluid MBUSA's "Factory approved service products broshure, part number S-0473-05A, edition April 2004, states:

MB Power Steering Fluid MB Part No Q 1460001 approved for W163 M-Class and W463 G-Class or use an approved Dexron III ATF (see page 6).

See we go to page 6. And there is lists these ATFs:
