Well update time. Installed external tranny cooler which drastically lowered my tranny temps. Now to the coolant issue... I found a leak. Doesnt seem to be leaking bad enough to cause an issue but still leaking... Its leaking at the plastic Y coupler that conects heater core, overflow tank, and water pump. Is that purchased as one whole peice with the 3 hoses already connected?
