ok, i have isspro gauge a-pillar boost,pyro,trans temp. i hooked them up yesterday and the dude at diesel manor said to put a tee in my line by the tranny so the sender that is in there will be hooked up also. i put the stock sender on the top and the isspro on the bottom. well maybe i'm wrong but i towed 6000 lbs today and the darn thing only got to 130* at the most when i was going slow. the temp dropped down to 100-105* when cruising down the hwy at 60. the boost was 7-8 and pyro at 650-700*. does this seem right? i just changed the trans filter and i added a bottle of lucas trans stuff and is says it lowers temps but it just doesn't seem right. i think the sender is in the wrong place but that is what they said to do so i did it.

 

Been there done that, it doesn't work, at least the tip of the sensor has to be in the the fluid flow. Where it will really get you is when the cold comes, it will take a very long time for the fluid to to warm enough for the stock sender to allow OD lockup.

What you need to do is install your new sender in the place where the stock sender was. Unplug your stock sender, put it in your toolbox, short across the two wires that the sender plugged into with a 1000 ohm resistor (25¢ Radio Shack)
What this will do is trick your computer into thinking the fluid is at normal temp.

 

thanks, i put it on the bottom thinking the flow would go out then down. i didn't think that was right but thats what the dude at dieselmanor said. but them guys probably haven't had lots of hands on experience with a 95 lately...

 

Hi, I ordered this part for my 97, 2500.. Supposed to work great.. should be real easy to hook up..

That's the best way to go with a '97 and newer. The older trannys came with a line just like that for the stock sender.

 

Whats wrong with a compression T just like in that pic? About 6 or 7 bucks. Tap the 3rd leg of the T with a 1/4 inch npt tap, use a 1/4 npt to 1/8 npt reducer, install the T in your current line (the fluid out line or the one going from the trans to the heat exchanger under the turbo). Even if you have to buy the tap, you still have $50 bucks in your pocket. KD

 

Probably would be just as good, just never thought of it in time.

 

I was told by "my tranny guy" that the stock lines on my 96 are alum and cutting in a T would be a DUMB!!! thing to do. I have read on here elsewhere that putting the sensor in the pan isn't a good idea either because the fluid in the pan is cooler than what's in the tranny, (Cooling fins, alum, double deep, etc, etc...).
Now, I've been reading this site for several years and have never seen a difinitive answer to the "where do I put the sensor" question. Did I miss something??
I want to install gauges, but so far, I haven't seen where any but a pyro would do ME any good, (see my sig for tranny and towing info).
Anybody have a suggestion or 6 ????
Thanks In Advance:

The best place is in the transmission cooler hot line (transmission output line to the cooler), because the fluid here has the highest temperature in the transmission, and thus this is the temperature you want to monitor. You can buy this line from Diesel Manor:

or you can buy a factory Dodge line (5011244-aa) that has a built in port directly attached to the line. You can screw your sending unit directly to this port. The Dodge line is about $140 and the Diesel Manor line is $80.

 

This a nice line, but you really dont need it - Look here:

Yes I actually got one of these Vulcan fittings, except that I realized that by the time the fluid reaches the point where this fitting is mounted, it already has passed through the coolant heat exchanger and/or the front cooler, so it will definitely not be the highest most accurate fluid temperature. So if you don't mind the expense, I still think the factory (or aftermarket) line is the best place to mount the sending unit, because the mounting port is right next to the transmission, so the fluid is at its highest temperature there. I assume that's why the factory put their sending unit in that very spot.

 

well i'll tell ya what i did. i peeled out the 13 dollars of brass fittings and installed the sender back in the line. then i put a 1k ohm resistor from radio shank and taped it off good. the temp runs around 130-150 and i had it up to 160-165 area towing with a gcvw of 18124 pounds the other day. only works on the older 12v engines tho, 'cause the newer ones don't have the port in the line. hope this helps someone..

 

The stock tranny lines are steel. Your tranny guy needs to bone up a little. KD
