722.6 Suddenly my Trans fluid level is very high

[Roncallo]

In preparing to go to FL the weekend, I was checking things out. I noticed my Trans fluid very high on the stick and starting to get a slightly brown tint. I have checked this fluid many times in the passed and while it is a bit tricky I have never been so surprised to see it so high and I don't recall adding fluid in the last 7 years. So I'm at a decision point do I go or do I stay.

The car in question is a 560SL using the power train from a 1996 SL600. See thread (M120 into 560SL). It is utilizing a complete power train from a 1996 SL600. Engine Trans Differential. My understanding is that the 96 722.6 transmission is very troublesome. The power train had 45,000 miles on it when I got it and I rebuilt the transmission to apply some updates. When I got into it I found the updates have already been applied meaning someone had trouble before 45,000 miles.

So the transmission now stands running well for the last 7 years but fluid turning slightly brown and unexpectedly high for some unknown reason. There is about 15,000 miles and 7 years on it since the last overhaul and maybe 30 to 50 blasts down the 1/4 mile.

Any MB techs with experience with this vintage trans.
