Good to know thanks

 

Nice info!

Please post your observed temps when you get things cookin'.

 

I really like that location on the dash. I think that's alot better than the 'C' pillar pod install I did...

 

Well it actually might not work for some. If you are too tall the shift selector might be right in front of the gauge in drive. I took a piece of paper and cut out a 2 inch circle and taped it up there and tried it first and it was perfect for me. I tried the area where the 4X4 electronic shift **** would be and the shift lever was right in the way in drive. Plus the fact that there was nothing behind the spot I chose in the dash and it accessability from the fuse panel it made it very attractive to go with that spot for me. But you realy should check like I did as it might not be the right spot for a taller or even shorter person. Then the A pillar probably is the next best alternative.

 

Very interesting post from one of our friends at Ford-Diesel.com. He was at the Diesel rally in Va. and Ford transmission tech was there. This is in reference to the 4R100 but some of the inferences are applicable to all of us.

Here's his post: "I originally posted this in the F-D.com forum in a thread by Jason about the VA Rally. Here ‘tis again: “About the auto transmission, the tranny guy mentioned both in individual discussions and in the group session that a TSB is coming to add an intake cooler; i.e., having a cooler in the bottom of the radiator, along with the current air cooler. He said (I think) that it is going into production soon. They feel this will solve the low speed cooling problem, as well as get the fluid up to temperature faster. I believe there was also mention of a transmission temperature gauge coming in the future.

The tranny guy said that 250 oF is the not-to-exceed temperature, and that they like to keep it below 200 oF. He also said that using the pressure port on the side of the tranny will give a higher temperature than in the pan, but lower than in the line going to the cooler. I think he also said that their existing temperature sensor is near the side port, but I’m not sure

He was also reluctant to recommend using synthetics. He said they did some testing with their own Mercon V and found it degraded some silicone seals. He said they haven’t
tested other synthetics, so they may not have similar problems. He felt that the single best thing you can do to extend the life of the transmission is frequent fluid changes.

I wasn’t taking notes, but I believe the above is correct. Feel free to add or correct.”The tranny guy (I wish I could remember his name) was asked directly if the side pressure port of the transmission was a good place to put the sender. His response was what I paraphrased above. He didn’t object to using the side port. He also used the phrase “time at temperature” as being the concern for transmission health and longevity. He also said it is plainly obvious when to change the fluid by the color and smell of the fluid.

Personally, I plan to install the sender in the side port, mostly because I’m not confident enough in my abilities to install it in the cooler line without messing it up, and because I don’t think that reading the max. temperature of the fluid as it comes out of the torque converter is significantly better than reading an average fluid temperature. This is, of course, my uneducated opinion, and I could be totally misguided. I currently don’t tow often, and plan to keep the temperature below 200 or so, and change the fluid when recommended."

 

Just never use teflon tape on any threaded connections where hydraulic-logic or any orifices are in use in any hydraulic system -- pieces of teflon can plug tiny holes and the teflon never get disolved.

Normal pipe 'tooth-paste', teflon or not, is best.

Not realy a problem on this type of temperatrue sender but you are right you have to use it carefully. Just as little wrap up near the head of the probe and only a light wrap so it breaks through on the threads so you get a good ground. This sender has no orifice to plug. But you sure don't want any of the tape inside the tranny either. I just wrapped a double tight layer around the rear half of it. There is enough room to do this and the tape only goes in around the last half as it tightens up.

 

I have installed a tranny temp gauge on my 4R70W with a 5.4. I used the autometer procomp ultra lite and I purchased the manifold that autometer sales for the sencing unit installation. I mounted it on the pillar. The installation was farely simple but I have some problems. My gauge never reads any temp. I installed it on the inlet to the radiator. When I put it in some water that is heated up the gauge reads fine but only after the probe is over half way submerged. If anyone has had a similiar problem I am open for advise. By the way I emailed autometer about this and they said there was a problem with the sensor and to return it for repair. I did this and got it back saying everything was fine however my sensor did seem sensitive to how far it needed to be submerged. They had me install it upside down which is in reverse to the way there instructions read. I did it and still never over 140 90 degress towing a 3000 lb boat. I dont think so.

I am not following you as to exactly where you installed the sender. Please explain.

 

Sorry I installed the sender on the transmission line going to the top of the radiator. The way mine is set up from the factory it goes to the top of the radiator out the bottom over to the aux cooler and back to the transmission.
