Automatic transmission failure

Post by johann »

Like so many fellow XC90 owners, I also experienced a complete geatronic transmission failure a week ago. I got the impression of a gear slipping, "Transmission service required" message showing and the transmission just completely failed. Techicians found no error codes even after reloading / updating the vehicle's software. ATF appears absolutely normal. But all are aware of the failing XC90 transmissions up to 2005/2006 year models....The one thing that boggles my mind is that the AW55-51 transmission has a maximum torque capability of 329 Nm, yet it is fitted to a vehicle with a torque rated at 340Nm. To a lay person that purely does not make sense. Are there any opinions or explainations?
