Transmission Tunnel Getting HOT
So here goes. My dad's 2008 S550 4MATIC has just been with us on a roadtrip. Our first destination was around 800 miles from home and I didn't notice the center console heating up too much.
But on the 2nd round, the car was feeling extremely heated after the 600 mile trip. I turned on the AC to low in the rear and it was blowing hot for 10mins after starting.
Even after cooling the air down it would heat up again for some time and cool down.
No error lights have shown up and this car is meticulously maintained at our local Mercedes Dealer.
Should we take it in just in case? I'm sure this is normal after a transmission has been running for a couple hours straight.
The engine coolant temps also held very steady throughout the trip if that helps.
