Thanks guys. I rang Pat303 and he told me to get Darren to select 3rd gear on the shifter and run it at about 90 to 100ks and you guys have confirmed what he told us.
Darren has been this for the past hour or so and he said that all seems to be ok. He is going to drive on as far as he can in the cool of the evening so hopefully that will help too. They are predicting temps in the high 20s in NSW for Christmas day so that may also help him. When he gets home to Newcastle he is selling the trailer but I think it will still be a good idea to fit a trans cooler anyway, after all they dont cost much and take bugger all to fit.
THanks fellas
