tranny side port 'vs' computer

[raycub]

I have an 01 EX 7.3 auto. I have a BD X monitor that ties into the computer for the tranny temp. Is this reading going to be the same as installing a sender into the tranny side port? If not what will the differences be?

i dont think so. I have the x-monitor as well, tranny temps seems to jump around sometimes. today it dropped 20deg in about 2 seconds, raised 15deg in 2 seconds earlier, really weird

in all i think the sender in the port is the most accurate

I have the X monitor as well cant say ive ever seen my bounce around like the above post. This time of year they tend to stay between 100 and 120

read up on the x-monitor, its not accurate until 140+

trans temps tend to be about 100deg over ambient temp

I had the X- Monitor and now I have analog ones with the sender IN the tranny... BIG difference....
the with XM, I was seeing an average of 140-150* empty on the Hiway.... with the analogs I noticed on my last trip PULLING a 8K trailer it never broke 130 UNLESS I was stop and go in town... ambient temps were pretty much the same as they have been....

also with the XM, once I would get out of town it's like it didnt want to cool down AT ALL! now I notice that once I get out and cruise it slowly cools down.... on my last trip with that trailer, I had about 100 miles of open road with some hills and such... when I left town, I was at 147ish and by the time I got to my destination it was at 106.... I know seems kinda low but I dont have that bypass thing and the ambient was in the low 30's...
