Alright guys, today's problem is transmission overheating. On my way home from vacation, my trans started leaking fluid out of the bell housing hole. From my research I've concluded its a seal. This seal can fail if it overheats but will get back in shape after it cools down. Now to avoid this problem again I'd like to put a beefy trans cooler system. I assume larger tires at highway speeds creates a lot of heat. Anywho, any info or suggestions would be helpful. BTW what's the purpose of an external transmission filter? Ease of access or something else.
