Volvo XC90 - how can I prevent gearbox overheating when towing?
I have bought a 2007 Volvo XC90 Geartronic D5 and plan to use it to tow a caravan, with a maximum weight of 1545kg. Is it advisable to change the oil cooler to prevent gearbox overheating?
Volvo actually offers modular oil coolers for these cars so you can increase the capacity of the existing oil cooler by adding another section.
