Trans Temp sensor 48re

[FPettijohn]

You must of not done much research.

Hmmmm..... wonder why there are so many test ports?



Well 1 of us didn't I will have to agree with you there! :-laf

 

[JCrockett]

Snoxracer, do you have any pics??

Glad you agree!

People just need to spend the extra money on the line. If you really want the true readings.

You don't have to spend the extra money to get good results, you just have to make one!



Well I'm trying to download some pictures with a new camera, so as soon as I figure it out I will post.



Thanks agian for your help,

Can't argue with that.

I'm just lazy! :-laf

Anybody know of material compatability issues? McMaster Carr lists a brass, a steel with zinc dichromate finish and a stainless steel compression tee, 1/2 tube x 1/2 nptf x 1/2 tube. Just pop a 1/8 x 1/2 reducing bushing in there and it'll be good to go. Brass is the cheapest.

I keep trying to send a picture with my new camera but it keeps telling the size it to big? I put the camera on the lowest pixel, and still says to big. I tried to crop the picture but that wasn't working for me either. Any suggestions, I just got a new Kodak easy share( so much for easy) . Thanks again,

Got a link for that?

I posted a picture on a different thread called DOES ANYONE HAVE A PICTURE OF THERE TRANS TEMP SENSOR? Hopefully it turned out ok,



Thanks,

I needed help with sender trans temp sender location & this site is all the help I needed. Thank you all !! ( first post)

The key word here is pressure ports. They do not flow oil, the oil dead ends at the pressure ports. It is like putting a temp sensor at the end of your hot water faucet rather than at the actual tank. You wont get a very accurate reading because the water will always read cooler at the tap rather ran if you took it right from the outline of the hot water tank.



The transmission oil pump continues to pump oil as long as your engine is running. It does not matter what gear selection the transmission is in, it still continues to pump oil. The transmission oil pump is a mechanical device, it is attached mechanically to your TC. The torque converter is bolted to your flex plate, your flex plate is bolted to your crankshaft, and as long as the engine is turning the transmission oil pump is pumping oil. Obviously people can put them wherever they want to but some of you may not be aware that the differences between measuring from the transmission cooler line and the transmission pressure ports can be as high as 150 degrees so it is an important decision .

Thanks Stefan for your expertise as a professional diesel transmission builder (Diesel Transmission Technology, DTT). DTT being one of the pioneers in performance diesel transmissions, your knowledge and expertise is very valuable to this board. Thanks for your participation.



Allnew2Me,

As far as being cheap, $90. 00 is better than $3-5K for a new transmission. I also have the Mass Diesel transmission line, it is money well spent!



When it comes the "Ghost Rider", I take the professionals advice. I only want to do it once, I want it right, and I want it to last! If I have to pay a little more now, I save a lot later!



DTT ROCKS! Oo. My experience and opinion!

Taped my sensor (that is one designed to go into the dipstick tube), yes that is TAPED mine with some heavey duty electrical tape directly to the out flow line from the transmission and it works great. Been there for 65 K miles on this one. No place for leaks, very simple and no problems. Was hauling RV's during most of that time and have never have had to replace the tape eather, now that I would not have believed. Just a simple, workable and inexpensive solution that works very well for me. Good luck

Why do you think the transmission temp goes down when you put it in park??? It is because the fluid quits pumping. The dodge autos pump fluid in any gear BUT park... why do you think you check them in neutral?? This is a well known fact and I was very surprised to see DTT's response to this. And IME, DTT is an arrogant know-it-all company that is way overpriced for what they offer... they jerked me around when I had cash-in-hand to buy a transmission for my 99CTD... they lost my business and respect during that horrible experience.



I had the temp sensor in four places in my 99 CTD's 46RE... pan, both pressure ports, and the cooler feed line (before the heater exchanger). I got the hottest reading and most/fastest fluctuation from the cooler line, which is known to be the best place. I got the lower and slightly more "delayed" readings from the pan... which you would expect since it is on the "cold" side of the cooler. Both ports simply got to a temperature slightly less than the engine operating temperature and stayed there regardless of driving/gear. One note about the ports, they do protrude into the case and into the solenoid and can interfere... but mine never did.



My transmission never got above 180*F... ever. That was a complete factory system with the addition of an autometer electric gauge and replacement of the transmission to intercooler hard steel line with a 3000psi hydraulic hose (the factory line kept cracking and leaking).

I think it does pump in park, it just doesn't flow through the cooler in park.

You need it in neutral for checking so the lines and cooler stay full which would effect pan level.
