Well there are places inside the transmission ports and servos that require high pressure if a seal blows these can cause high pressure inside the non pressure areas. But you would have other problems aswell. The cooler is just a possibility the other possibility is worn parts causing external leaks.
This is not a common problem so there will be no common answers troublwshooting and inspection of parts is the only way to fix this problem.
