Jim,

I did a cursory review of the transmission section of MM X-7525 but couldn't find any info on testing the transmission and where you
check the pump output pressure or how much pressure should be supplied at any given RPM.

A LOP switch could be wired in just to turn on a light and or buzzer when that pressure went too low.

I have a Digi-Panel that monitors the temperature and I would think that as the fluid level dropped the temp would go up. However,
by the time it went out of spec the transmission might already be toast.

Regards,

Kerry,

I was referring to the LOP switches that sense loss of pressure and open the ignition circuit. When they fail open, you have no
spark. Sorry if my answer was confusing.

Jim
