Good day together I’d be very grateful if someone could help me with my problem. I’ve had an XC70 Jg. 2003 for 2 months with 40,000Km. Two weeks ago I went on vacation with the car and my trailer (1200kg). I drove quickly over a pass that was quite long (passenger ride about 1 hour). After about 3⁄4 hours the warning triangle turned yellow with the message “Check transmission”. About 10 minutes later the automatic transmission turned off and also the Geartronic did not work anymore (i.e. I could no longer manually switch). At the automatic transmission the engine was apparently not cooled down again and the machine works again. Then the warning triangle turned red with the message “Check transmissions” lighted up. Then I parked the car and called the breakdown aid. When this arrived the engine was apparently not cooled again and the machine works again. Just the yellow warning triangle lighted up with the message “Check transmissions” lighted up. Then the breakdown broke my car service then. Now the engine update was burned up and the engine changed again.
