Warning message: Trans oil overheated

[alinak17]

Hi all,

Mercedes CLA 1.3 CLA 200 AMG line Coupe 2022

Got this messsge today whilst driving vibrations whilst accelerating and a slight clunking issue at times.

Anyone know exactly what is it and how much to fix?

It's oil over its ideal temperature, performance range. May be time for it to be changed?

Age? Mileage?

2022, 37k. Thank you

Been for a hard drive at all ?

Has the message just happened once, or often?

Any better after an overnight cooling off?

Speaking honestly, used to rag it about. Wasn’t any better this morning, had it serviced a year ago, B2 service isn’t due for 177 days, hoping it’s just the oil, booked it in for a service tomorrow so will let you know if it’s any better. Message only popped up once for a millisecond, went to the owners manual and that message in the picture was there. Car also feels like it’s slipping gears
