I'm installing a temp sender in the PTO Cover on my NV5600. I bought a B&M drain plug from Geno's. It is tapped to accept a 1/8 NPT plug so I'll be putting the drain plug in the PTO cover and screwing the sender into it. I need to know if I should install the sender below or above the fluid fill line. I read somewhere on TDR a discussion about this, only it was regarding the differential covers. If I remember correctly the thread said above the fluid level was the appropriate place (it’s hotter there). My PML cover has the sender above the fluid level. I have the PTO cover off and will put the sender in a location that can go either way, simply by rotating the cover 180 degrees. Please post your opinions.
