Cheers all! There's a plastic end tank unit on sparesbox. It's $340 ish with shipping, so will be here in half a week and has the real warranty. I'll be getting one in the morning. Got a hayden viscous fan and gates waterpump too from rockauto. Should be back on the road end of next week. By the way I'm not using the trans cooler in the radiator, I have a seperate one
