Thanks Tannaton. From what I can make out Volvo felt the lower revs needed in the D5 would mean less heat generated in the oil but I think I'll probably fit the extra cooler to be safe. The fact that the recommend changing the gearbox oil every 50k miles if towing makes me suspect there is some oil degradation from excess heat
