Working on a weekend project adding a Transmission temp Sender to a 2004 TJ, like to get it installed on the output line to the cooler.
Are 3/8" OD is the line OD Diameter?

Jeep is away and no like to get caught below somebody else TJ measuring this line...:facepalm:
Thanks in advance!

Temp sender belongs in the transmission pan. The only thing you want to know is how hot the transmission is. But if you insist on being silly, the lines are 3/8" OD.

All depends on what information from the process you like to know and where on the process you need to monitor the same.

Why Silly? Because think different?

Not because think different but because that information does you no good unless you add two more temperature senders to the system. One in the pan and one before the cooler with a switch that allows you to compare the differential temperatures between the 3.

The one out of the trans to the cooler is not a good representation of what is going on because it is the hottest the fluid will ever be due to it just leaving the torque converter and it begins to cool almost instantly simply because it is hotter than the rest of the system. The one out of the cooler tells you that the cooler is working but it does not tell you how hot the transmission is and the transmission temp is the ONLY one that matters.

If you want to know what the cooler is doing, put one right before and right after the cooler. If you want to know how hot the transmission is, put a sender in the pan.

You have a pretty good idea of what we looking to do.

My question was based on the first sensor location that to easy out the install work and elimination after the test we will conducting.

Then we will probably left the pan located sender that is where less Temp measure surges probably happens during the process and kept the gauge reading more stable looking.
