Where do you guys put the sensor for the transmission temp?
Is it in the pan or in the transmission somewhere?
Also, do you guys have an electric gauge or the mechanical gauge?

Thanks for the help

 

temp sensor on a e40d and 4r100 goes on the driver side of the trany in the pressure port.this is a 1/8 pipe plug near the middle of trany.

 

Thanks catmech. I was wondering about that.

 

I have an excursion with the tranny temp guage. Is that 1/8 plug still available or is that where ford put the sensor for the factory guage? I was told that the fact temp sensors are really just switches. Although mine seems to come up gradually which would inticate an actual guage. Any info would be great. Thank you.

 

I coupled mine in on the return line. not sure how accurate this location will be. used the same block that cyclone fan gives you

 

That port is available. The Ford gauge uses a sensor that is internal to the transmission.

 

thank you very much.
