Aoto Trans Hot Line Temp Probe - Help
OK, I'm ready to install the trans temp probe on my 05, 3500, Cummins. I have decided to put it in the hot line to the cooler. I understand this will give the optimal temp readings as this is coming from the TC. True?
Is the front line coming out of driver side of transmission the hot line? I plan on adapting an oversized (3/4') T into the line to prevent restricting fluid flow. Then put the probe into the T side of fitting.
Am I using screwy logic or does this seem a reasonable solution?
Any advise appreciated.

Thats what I did. I used a compression T fitting the same size as the line. I like to watch the temp rise and fall at different loads and such. It confirms my original thinking that in the hot line is best.

It drives me crazy watching the temp hit 220 while just idling at the light. I'm thinking sometimes ignorance is bliss...

Is the hot line out of the tranny 3/8" o.d? If so a stainless steel "swagelok female branch tee" would work great if you can find a dealer that supplies them. If there are any companies around that deal with high pressure fittings or semiconductor installs they might have them. The tee has 3/8" compression fittings on each end and a 1/4" female pipe thread branch where you could locate the sender. The swagelok part # is SS-600-3TTF. All you would have to do is cut a small section out of the factory line for the tee. They are easy to install and when installed correctly they will not leak. They are not the cheapest fittings around but I think they are by far the best. We use them daily with some pretty high pressures and I have never seen one fail when installed correctly. I am guessing it will cost you around $30 for one.

If you get the replacement line from Diesel Manor you will also have your stocker as a spare in the odd case that it ever did leak.
Mine will also hit 215 after running hard and then sitting in traffic idling in D. I think the tighter TC creates more heat when idling.

Yeah, I am sure my TC is fairly loose! The swageloc dealer that I talked to about the fitting said it wasn't really necessary, and was quite a bit of overkill for the application. They said for the fluid being used and the pressures in the trans cooler that a typical compression fitting was fine. Swagelocs are used in corrosive lines, gas, and acids type things.

I *think* Diesel Manor uses Swagelok brand fittings on their replacement line. If the fittings are $40-$45 then that makes the $60 price for the new line pretty darn cheap.

That is a good price, but like I said above, I think it is brass, which is substantially cheaper. I just didn't want to wait for the line, or pay for something I can do myself considering I didn't need a new line at the time.

swagelok fittings
You are correct about the Yor-Lok fittings. You can also get a similar fitting made by Parker, Ham-let and Hoke. There are probably others too. The price I quoted earlier was from a place here locally that we do a lot of business with. Its very possible the prices are higher elsewhere.
FYI, if the line size is 1/2" o.d. then here is the swagelok part # if anyone is interested: SS-810-3-4TTF. This is for 1/2 swagelok ends and a 1/4" female threaded branch. SS-810-3-6TTF is for 1/2" swagelok ends and a 3/8" female branch.
Like vzdude said, they are a little overkill but they are some very high quality fittings. Im sure there are other fittings that would work equally as well in this application.

All of the swageloc dealers I called said the same. They were all stainless though. The diesel manor line appears to be brass. Which is fine, but cheaper.
