Transmission temp gauge sending unit
 
Hello everyone!

I would like to know where the best location to install a temperature sending unit for the transmission is and why?

If it matters the transmission I would be installing it into is a th400

Most aftermarket trans temp gauges I have seen put the sending unit on a tee fitting plumbed into the trans oil cooler line. This link shows the kit from B&M: B&M Automotive B&M Trans Temp Gauge Kit - Transmission Temp Gauge - Gauges & Mounting Kits - Interior Parts & Accessories - by 4 Wheel Parts

This is where mine is located and as far as I'm concerned, close enough for anything I'm doing with my car (trans. temp. runs within a couple degrees of the engine coolant temp (175-180 on a 90 degree day):

That bung that you installed to your pan for the sending unit, is it just sealed by compression with rubber gaskets?

It just takes a seal on the outside - you still need to have a ground - l drilled and tapped the cast pan. Got the sending unit from Egauges.

Nice clean install. Looks much cleaner and stout than trans line method.

So the bung is not welded? where did you purchase it from?

Ok I will search for one there. Not the sending unit itself but the bung that goes into the pan and see what I can find.
