I am planning to install a B@M temp gauge on my Dodge Ram 1500 V6 42 RH Auto Trans. I have conflicting information as to where to install the sender unit. I have not picked up the gauge kit as yet but indications are to install with a T fitting in the OEM cooler return line just after the cooler. Other information is to install in the pan. Any one have first hand information as to which is the better spot. Thanks

 

You want to install the tee as close to the tranny as possible in the line that GOES to the cooler for the most accurate reading. And get one of these "T"'s ,the 3/8ths is the one you want. http://dieselmanor.com/dm_products/FTG-MFD.asp

 

i saw an affordable trans temp gauge kit from B&M that included that T.

I like to install them in the pan because the pan is not pressurized and, at least with a deep pan and an extended pickup to keep the filter submerged at a level lower than the sensor port, even if the sensor falls completely out I'm still getting safely on down the road. I don't like the idea of the failure of a convenience monitoring system cascading to become failure of the critical component it monitors.

If you're as paranoid as I am about such things, the rule of thumb is to assume a forty degree temperature rise in the transmission, e.g. 140F in the pan is 180F on the hot side. It's not guaranteed, but it's workable.

 

Thanks for the replies

 

Having the T inline will tell you a lot quicker if there is a problem as opposed to having it in the pan. IMHO

 

There are quite a few write-ups in the 2nd Gen Tech forum, complete with pictures, where people installed a "T" line for running the lines to the gauge(s).

 

True, and no argument will come from me on that point.

 

I installed mine in one of the test ports Silver_Dodge recommended in a past thread. Has worked great. No leaks, no worries here. And its mounted in such a position its not vulnerable to being broke off.
