RIDOFPWRSTROKE, When you go to the dealer and ask for that part number, don't be surprised if they say that there are a couple other adapter fittings that are required as the original '94/'95 part# has been superceded. Decline the extra fittings as they are common brass reverse-flare-to-NPT fittings.. One was pretty cheap but the other one was WAY overpriced ($31.00)!!!
Just get the line which has a 3/8" NPT-F hex boss brazed onto the hot oil return line.
My 97 already had the required brass adapter screwed into the tranny case.
If you DO need them, go to a well stocked NAPA store and pick them up. The money you save on that one fitting alone will allow you to stock up on beer for several truck projects!

Rattler, thanx for the help. I had a pwr stroke at one time, but fuel economy sucked and I had problems with the motor twice with the pushrods and valves. Stepped up to a cummins and now I have 2. One for me and one for the wife. I have never had an auto, so hooking up the tranny temp gauge has many ways to do it. I thank everyone for their help and I will be getting the hose when I get home. Too bad the 98's didnt come with the hose with fitting for the temp gauge. Thanks for all of you help.

 

I had a shop tell me to put it in the middle port on the passenger side. They gave me a T fitting with male threads on one side and on the other two sides were female. One for the sensor to go in and the other for the plug I took out. So in the future they can do pressure tests with out removing the sensor. I have a picture in my gallery of how I did it if that helps.

 

JOLLYGR:I've heard that too. I did a lot more reading and finally decided to go to the oil exit line method. That oil is generally the hottest as it has been heavily thrashed around inside the torque converter before being sent on its way to cool down. Quickest heat response (sometimes too quick )but it does let you know what's happening almost instantly.
If I had an aftermarket tranny pan, simply threading the sensor into the pan would've been my obvious first choice.
An OEM temp sensor is already deep inside the pan on my '97, but I didn't want to jack with the tranny wiring and possibly cause problems by tapping into a signal wire already used by the TCM.
The 94/95 hot oil line method is a very simple/reliable solution (albeit a little $$).

RIDOFPS:Welcome to the world of Cummins powered vehicles.. The engines are a dream, and you do what you have to to keep the vehicles around them functional to enjoy that engine.
Thank goodness we have such a delightful forum like DTR etc to glean mega amounts of help from other users...

I wouldn't trust the readings you're getting, they will be way low. The middle port only works on the earlier RH tranny not the RE that you have. Even on the RH the sender needs to be in the flow of fluid, not outside in a tee.
