I've got a VDO 400F trans temp gauge in my truck, I have not seen it
come off the peg, I was thinking it should get over 200F as soon as the
engine is warmed up. Do the VDO gauges have high resistance at low
temps and low resistance at high temps as one would expect? (that is,
can I ground the sender wire and see what happens for a rough check?)
It is possible that I am not getting an accurate reading as I did not
braze a bung into the pan, I installed the sender in a pressure test
****t on the trans so it might actually not be warming up properly.
Also, it appears that on my trans (Ford E4OD) there is a hole in the
middle of a pan to be drilled for a drain plug. Anyone know if there is
a piece of metal inside there that can simply be tapped for a pipe
thread or is there more involved than that?
