Abstract
A sensor assembly for use with automotive transmission systems includes an overmolded lead frame 10 having a plurality of sensing stations 16, 17 18, 19 20, 21 and 22. A temperature dependent resistor 32 is encapsulated in a post 42 integrally formed with the overmold at temperature sensor station 16. Post 42 is adapted to be received in a bore 68 cast in the transmission housing wall and serves as a datum to position the mounting holes of the assembly in alignment with selected bores in the transmission housing. Temperature sensing station 16 is circumscribed by an annular rib 52 which cooperates with a plurality of protrusions 62 to receive therebetween an O-ring seal member 54.
