Anybody know where to get a valve body for a cast iron 1955 transmission??? Thanks Jerry
Jerry.....I have one in a good PG that I removed for the 700-R4 installation.....However, I want to sell the whole transmission and you'd have to pick it up.

The same valve body is used on all 1955-57 Powerglides. The part number is 3740047 (cast 3740048).

Finding a new valve body will be difficult. Used valve bodies with high mileage end up with a wear groove from the steel sealing ring on the input shaft. This wear prevents the ring from sealing properly, which causes the torque converter to leak down when the car is parked for an extended time.
