I checked the wiring twice, I have 12v going the gauge, its grounded, it lights up and dims
with the other gauges but it registers zero degrees. I took the truck for a test drive and
observed under WOT 800 degrees on the pryro and 24 max PSI on the boost with the Edge
set at level 4. Should I see a voltage on the trans temp sensor if its working properly ?
I have a meter and checked and got nothing on the VDC settings. Is the temp sensor defective ?
everything is brand new. Any help or trouble shooting would be helpful. I also by passed the wire
from the temp sensor with a new wire diretly into the cab with the same results. I was thinking
maybe I shorted the wire but I didnt.

 

What gauge, manual or electronic, where is the sensor installed?

 

Transmission temp sensor located in trans pan. Dipricol trans gauge, automatic transmission

 

I have the same gauges as you, and installed in the same location. I almost sent my gauge back thinking it didn't work. I was wrong. Tranny temps take a LONG time to heat up. My needle rarely comes off the peg unless I'm towing, and then it will only get to 100 at cruise, or towing in stop and go traffic, then it can get to 120+, or back up the RV in the sand, then it will climb to 180 very fast. My guess is that everything is OK with you set-up. Give it some time on the road.

 

False alarm...it was too cool about to get the gauge to climb.
I drove it on the highway and then stop and go traffic and it
finally climbed to 115 from 100 (lowest setting)
Thanks Everyone, I appreciate your help.

 

I have mine in the HOT line from the trans to the heat exchanger.
Theoretically the hottest point in the system.
At highway speeds the converter is locked, and I don't even see a reading on my 140* (lowest reading) gauge.
In town traffic will see temps of 190 to 200 unloaded in the warmer weather.

 

what did you use to get your sensor mounted in the hot line????
part numbers,etc????

 

The part number at the Dodge dealer is CH05011244AA.
This line works on the 47REs, not too sure if it's the same on later (48RE) years.

 

with your sensor placement , what reading do you think it would get to if you had a load on , in hot weather .. and just for discussion .. why do you think this is a better spot then the pan ?? i have my gauge installed and working except my trans temp and i still haven't decided where the best location is ... thank you for any info ..

I've seen temps in the 220-230 range in the summer time, not under big loads in traffic.
The Hot line is usually prefered as it show the temps straight out of the trans instead of after the fluid has traveled through two coolers.
By the time the pan fluid has heated up to a noticeable temp it's probbaly already cooking the trans.
Running tighter aftermarket converters can also increase temps in traffic.

 

I think the difference in measuring at the "Hot" line and the pan is about 30 degrees. In the pan you are measuring fluid that has already cooled. The hot line is measuring the fluid after it goes through the trans. I got lazy and got the dipstick sensor that you snake down the dipstick tube and reads the temp from the pan. I just always keep in mind that my temps are really 30 degrees higher than the guage says... (It's still better than no guage!! )

 

great !! thanks for the info .. i half always sided with the in line temp sensor . thinking that is the way to go .. i think i will order that hose with the fitting in it from mass diesel ..
thanks again for the information
