Trans oil overheated drive on with care
Temperature readings after driving all day
Hey guys,
I haven't driven the SLS in months and took it out today. Car was running great except for a warning light that came on at the end of the day on the multifunction display that said " Trans oil overheated drive on with care". I have never seen that before
Has anyone had this happen to them before? Not sure how to check trans oil level either if its even low or if that's a possibility. Any info whatsoever will be very appreciated!

Oh wow Sounds expensive!! Is that internal or outside of trans, I'm not familiar with the set up unfortunately. I took it to my local MB dealer here in LA and they came up with these codes for my car. I thought there was an oil temp sensor inside trans failing that needs replacing. Unfortunately trans is sealed and needs to be cracked open to fix, was hoping to avoid that which basically is a trans rebuild. Besides that car runs great and shifts perfectly. Also my trans temp only got to 194, thought it doesn't get dangerous unless temps get over the 200 range.
Codes Found-
071064 Transmission oil temperature sensor 1 has
an electrical fault.
There is an implausible signal 06A900 Output 4 for
the reference voltage of the sensors has a malfunction
