For those of you odering the digi-panel, suggest you buy an additional sensor
for the transmission. I did for bout $8 and I added a small switch which I use
to change from one cooling line to the other. That way I can measure the cool,
and hot lines from the trasmission by flicking a switch. I used one of the
miniature switches and used the blank hole next to the on off switch to make the
connection. Works great.
