Were is the best place for a trans temp sender ? hot tranny line. or tranny pan ?

I just installed one last week and I installed it in the tranny pan. After reading many post on this forum, most responses recommended this location to get the most accurate reading. I also changed the trans filter at the same time.

Mine is installed in the tranny hot line. I want to know how hot the fluid is, not the temp. of the fluid after after it's been subjected to work, ran through the cooler and cooled in the pan.

I added a Mag Hytec dd tranny pan when the turck had 15k miles on it. The pan comes pre-drilled with a tranny temp guage port on the left side of the pan - midway between the top and bottom. So, that is where I installed mine. While it may not provide the fluid temperature from the point desired by many, it is still a point of reference. The temperature runs anywhere between 150 and 190 degrees depending on ambient air temp and solo/towing driving. I figure it's better than strictly relying on the tranny overheat idiot light. pcm

I run a Dashhawk monitor in cab, and pull the info from the trucks computer.

Not sure where the info comes from, but it is consistent with the temps that others report.

I put mine in the hot line also. It's more sensitive there. Just backing the boat up our driveway the temperature will increase from 160* to 180*.

IMHO, the ideal thing to do is to run two gauges, one reading the pan and the other reading the line. If only one gauge is used I like it to read the pan because it tell me what is going on with the whole fluid system ie trans, cooler lines etc. If the pan fluid is overheated you are really pushing beyond the whole system's capability.

The fluid in the pan has alrredy been cooled. The hot line will give you a quicker heads up of trouble.
