ABSTRACT:
A transmission fluid pressure indicator which comprises fluid pressure-responsive electrical switches engageable within the pressure taps of an automatic transmission and being adapted to be urged into circuit open condition when the fluid pressure in said transmission is at or above a predetermined level. A signaling device, such as a light or a buzzer, is in circuit with said switches so that when the pressure of the transmission fluid descends below the predetermined level, the circuit will be closed and the signal energized to indicate such condition to the operator.
