I have a 2000 A/T Sportage with 137K miles on it. The stock A/T oil cooler is a no fin tube type above the skid plate beneath the radiator inside the engine bay, while the 1998 Sportage model has a stacked plate type and located infront behind the grille which I think is more efficient. I'm planning to bypass the radiator and change it with the 98 Sportage A/T cooler. Will there be any transmission oil pressure issues? The gulf ranges 105F to 125F during summer months and I often pass through traffic a lot. The coolant boils everytime I turn off the engine but it doesn't overheat and I always check the coolant level with a 50/50 mix. I'm worried for the transmission to be damaged with the coolant boiling and it will also reduce the heat inside the radiator without the transmission oil passing through the tank. Anybody bypassed the radiator without having problems with the transmission?
