transmission cooler fan

top of the hill the temps just faded away

That's exactly what's I'd expect with the sensor mounted at the outlet. You ease up on the throttle, decrease heat generation, and see it right away.



With the sensor in the pan, you'd see the temp go down much later, as the overall pan temp goes down.



I'm going to mount a sensor where you did with a switch so I can look at the outlet or the pan temp.

Trans temp sender pics

It's kind of hard to see at first, but you can make out the 1/2 inch line and the way the T and sending units plug in.

This is hard to explain, but here goes - The top of the 'T' is male on one end and female on the other, and the bottom of the 'T' is female. This allows you to plug into the factory fitting, and then plug in the factory and aftermarket sending units. Remember, liquid Teflon is your best friend in this install, in fact for any install where pressure or fluids (except fuel) are concerned.

Hope this helps!

Not sure how to insert the links, so here's the pics:

Great Pictures

SamsRams,



I like that sensor install. I'm gonna do one just like it.



But the discussion on the other thread and here where you think you have a different installation than mine has me confused. Confused because it looks just like mine.



My first picture in the set:



https://www.turbodieselregister.com/user_gallery/displayalbum.php?&albumid=893



shows the stock sensor for overtemp that attaches to the trans outlet pipe, and below that a 90* turn compression fitting connecting to a hose. That hose curves forward, up, and outward to the frame rail and continues turning till it goes back to the cooler under the bed.



Your second picture looks as though that same turn does the same thing.



Also in your picture, it looks like the hose coming in at the left and straight-fitted to a pipe going to the passenger side is the same as mine going to the heat exchanger under the turbo. Just like mine.



I think we have the same installation, but maybe I'm not describing it quite right.



I'm going to try to add your two pictures to my set (with proper attribution, of course), so people can see them together.



Tx, DBF



(Ed. Note) SamsRams two pictures of his neat trans temp sensor installation are now in the set with a link in this thread. DBF

You need to be aware that the temperature at your sensor is going to be cooler than the actual temperature of the fluid traveling through the tube, I don't know how much temp loss there is by moving the sensor away from the tube with the T but there has to be some, just not sure how much.

Just be aware,



Happy Rammin,

Trans temp fittings and part numbers

Okay, lessee here - I dug up the receipts from NAPA for the T-fitting and the additional reducer fitting for the aftermarket temp sensor - I'm 99% sure these are the actual ones I bought - first set was too big. Here goes -



T-fitting: pn# 3750 x 6, $7. 01

Reducer: pn# 3220 x 6 x 2, $1. 59



You'll also need some liquid Teflon goo in a tube, (I don't like the tape).



Hope this all helps - so far I have had zero leaks and great results.
