Decided to make a new (top) PTO cover for the SM420 to accommodate the new transmission fluid temp gauge. 3/16 plate cut out on water jet will have 1/4 NPT tapped hole for sending unit. As long as I measured right, the tapped hole location *should* put the sending unit in fluid but out of way of gears.
Trying to decide now whether or not I want to have a "guard" surrounding the sending unit to protect it and signal wire from ground/road debris.
