The transmission does a lot of work for keeping the engine’s RPM within a usable range. And it is the oil cooler that keeps the transmission cool. Installing a transmission cooler is an additional prevention against transmission overheating. The transmission oil cooler comes in two types. One is the radiator system and you will find the other in the close proximity to the vehicle’s air conditioning system. Sometimes, even regular aftercare can’t prevent the cooler from failing. Better you stay knowledgeable about the signs of failure- so that you can repair or replace the cooler taking the help of a PORSCHE specialist before encountering a breakdown.
