Just got in my gauge and trying to figure out where to install it.

I read on cooler lines is better, but I also read on pan is better.

Which way and where to tap on pan ?

 

Well there are a variety of places that you can go. The hot cooler line is going to show the hottest temps(my personal preference). The pan will show well the temps of the pan fluid after the fluid has been cooled. For the pan you can go just about anywhere in it as long as you are about 1/2 way down the side. I would not go from the bottom though you could. There are also a couple of test ports that you can use but be careful if using one of the test ports. One of them doesnt have fluid in it all of the time most but not all if I recall correctly and the other thing to watch out for is to make sure your sender doesnt protrude too far into the test port as the one to use has a piston in it and it does travel most of the way up. There have been reports of that piston breaking if it hits the sender. Not all senders will protrude that far in and a simple bushing can take care of it if it does stick in too far.

 

So which is better ? I assume the cooler line, since it shows actual temp of it while is getting into the "danger" zone.

pan should be ok too but I need to know what's the temp difference usually between the 2.

Also what's the best way to connect sender to line ? Can I get a fitting from hardware store that has in/out from line + a port for sender ?

How about installing it in the cooler itself near inlet ?

Sorry for all these questions, but since there is drilling involved I'd llike to do it right the first time.

 

Just did my wifes tranny temp sensor yesterday. I bought the line from dodge for 95 bucks and it has a 1/4" fitting for the tranny temp. Highest I have seen is 160. No pulling though. Much more accurate on the hot line. That line makes it very easy to do. My 02 cents

 

Hows the install?

 

The install is easy but you will lose about 4 qts of fuild.

 

Geeez, another 95 bucks for a fuel line ? I think I've got to start a Diesel part store, looks like there is a good margin on this, better than boats......

 

I installed mine on the drivers side of the pan. It's best if you braze a bushing on. That way you have something there other than just the thickness of the pan. Works great!

 

If you mount it on the tranny pan, temps wont be as accurate. The hose was a direct swap. Then undo the cap and put in the sensor. Pretty darn easy. I put all three gauges on her truck yesterday and it was just as easy as the boost. Well all three are pretty easy, but this is a no brainer. I would get the tranny line as it is telling you exactly what the fluid temp is coming out of the torque convertor.

 

I have some pics up of the lined one with sensor and one with out.
