I will be towing a caravan with total weight up to 1600 kg with my 2004 VY Commodore Series 2 Equipe wagon. I have asked Holden whether this car has a separate transmission oil cooler but could not get a definitive answer. Do you know if this model has one and whether it would be sufficient for the job or would it be better to invest in an aftermarket kit to ensure it prolongs and protects the transmission?
The VY oil cooler is in the radiator and is generally trouble free, but the guys at AW Automatics recommend an external cooler for all towing applications.
