Transmission Switch

Connect vacuum gauge in line to distributor vacuum advance unit. Put transmission in reverse on Hydra-Matic or high on manuals and Powerglide.

NOTE: Powerglide equipped vehicles must have rear wheels off floor and accelerated to permit shift into high gear.

Observe vacuum gauge for a manifold vacuum reading. Replace transmission switch if gauge has a "O" reading.
