Yes, Ive been warned by a mate who is in the rad trade to be careful of aftermarket radiators for automatics, he said the lines inside the tank are also smaller & have trouble cooling autos. He said generally the Radiator themselves will work OK for a few years, but be careful for an auto

The best way to get yours going is to buy fittings with spiggots for the rad & a short length of the orange coloured transmission rubber hose (ortang??) something like that

cheers
