Hi guys. I am looking at installing a tranny temp gauge for my 2001 Supercrew 4x4 with the 4R70W transmission, and i need input on where the best location for the sending unit would be. I have heard there is a test port directly on the transmission that could be used but will this give me accurate readings. any body tried this set up? Thanks

 

Yes, the test port on the side of the transmission will give accurate readings.

could someone explain the install of the gauge in a little more detail to me as i am unfamiliar with the trannys on these trucks and i wanna install a gauge...? Thanks!

 

And some nice pix and spec's for specifics would be real neat.

How about some electro-geek coming up with a sensor and circuitry that would use the console temp gage and subtract 100 degrees so that I could read it instead of the outside temperature.

I remember many threads from way back mostly from cphillip....

At the time I was looking into installing a sensor but never made it that far.

You can start with these threads.....

I have an Autometer Phantom gauge, it will go into the test port on the side of the tranny, even the right size. I'm thinking about running a T on the converter out port to get the higher reading, but the line pressure port will give you a pretty good reading. The important thing is to establish what's "normal" for it, and reacto to any change in whatever the gauge reads.

NEAL has posted before that the test port is not a good location due to the heat build up from the tranny casing and exhaust. He stated...and makes sense that the best place is to place it inline from tranny to cooler so you get an accurate reading before it goes to the cooler. I am planning adding a tranny temp gauge myself and will be using the autometer manifold. Here is his post on f150world:

HI!... You don't want to use the ports on the side of the tranny body for your temp sensor probe. You will get "HEAT SOAK" from the tranny housing (aluminum), plus the exhaust system runs close to the side of the tranny housing as well and this will create even greater "HEAT SOAK". You want to use a tranny temp guage that is 'MECHANICAL". Stay away from the electrical ones, they are not very accurate and the "MECHANICAL" ones can be used to monitor your temps while the vehicle is off. Get yourself a AUTOMETER tranny temp manifold. You splice it into your tranny line and the AUTOMETER temp guage probe screws right into it. It comes with compresion fittings. Make sure you use TEFLON tape on all threads. I installed my tranny temp manifold in the tranny line running under the radiator cross member. Make sure you tap into the outgoing line from the tranny to the rad. DO NOT tap the manifold on any lines that come from the rad or tranny cooler going back to the tranny. If you do you will not be getting accurate tranny fluid temps because the fluid has already been cooled through the rad and tranny cooler. You want to take the temp of the fluid exiting the tranny. NOT going back into the tranny. If you have done it the other way, You have done it WRONG, and I would highly recommend that you switch it to the out going tranny line. Here's a pic of the manifold and my set up. PART# for the AUTOMETER TRANNY TEMP MANIFOLD is 2286 for 3/8 O.D tubing and PART# 2287 for 5/16 O.D tubing.

 

I have a sender unit and guage but have not yet installed them in this truck. I had it in the test port of a previous vehicle.

I found this link in a RV conference. This looks like another alternative. You can attach this thermocouple to the dipstick.

This whole site looks interesting for those of us that toe and RV.
