Here is just a thought. Rather than putting it in the oil line or tranny. Clamp it with a hose clamp to the oil line if there is a metal section. Then insulate the line and sender. You can use that wrap around insulation they use on A/C expansion valves, any outfit that does industrial A/C has the stuff. It would be a little slower to react but you don't have to worry about a leak.

 

Not only would it be slow, it would be so inaccurate.

 

This is what I did, spliced a tee into the trans outlet line. Cost around $10 for a brass tee and bushings.

 

Temp Sender

When you spliced it in did you cut the line or did you just unscrew it from the tranny?

 

I cut the tee into the short piece of rubber line on the passenger side of the radiator.

 

I took the easier and safer way of paying an off-road shop $100 to weld the sender into the tranny pan. Because our tranny pans are somewhat thin he welded an extra piece of metal on the inside of the pan on the driver side and tapped the sender directly through the thick weld. It's a nice and clean looking set up and hasn't leaked a drop. Just find someone who knows how to weld really well. Good luck!

 

Well.....when Mag-Hytec finally comes out with the transmission pan, I am going to get one of those with a port already tapped for the sender.

 

or just use the service port that is on the tranny. it a 1/16 fitting and can be had by searching for a fuel rail for a ford.

 

Transmission Temp

Thanks. I have read about this. However when I look at my transmission there seems to be only two test ports. Would any of the test ports work and if so how do I go about looking for a fuel rail. What part am I specifically looking for?

 

Transmission Temp

Sorry. When I say what part I mean what part from the fuel Rail.
Also I have a 2005 ram with the 545 Transmission and 5.7 engine.

 

i just cut the line and picked up a tee from home depot. it has never leaked and it has been there for about 3 years. i actually could not even tell you how it is set up because its been that long, and i have never had an issue with it.

 

When you guys are cutting and T-ing the line are you having to flange the ends or using brass ferrells?

 

the brass compression fittings that look like a wedding band

 

Thats the ferrells. THX.

 

I used the following on my truck. I placed it above the cross member at the transmission so that it would be protected from ground debris.

It has been on since June/July of 2004 and I have not had a problem. It works well.

If given the chance to do it again, I would use the port on the transmission though.

 

thats how i did it. its been a couple of years now. no issues. doing it like this is supposed to give you the most accurate reading.
