ok i am getting ready to run lines from the th400 to the cooler and i wanted to know which of the two fittings is the send and return. i have an auto meter trans temp guage that i want to put the sensor in the send line. the two fittings on the trans are one on top of the other. thanks

I will try to find my TH400 book. I can not remember right off hand. I am thinking it is the top one, but I am not certain. Hey, I've got a 50/50 shot.:rolleyes: :confused:

top it is.............;) :beer:

well that is good because that is where i ran it. i just guessed that the top would be it and i guess i guessed right.:D thanks guys. the th400 is in and work good!
