Great Finds Phil
The top loading DW is WP built, NO D&M here. WP bought the complete GE motor pump and SS Bowie-tie impeller from GE for its less expensive DWs both portable and BI in the early 60s. The better DWs had a black Bakelite wash arm and a Gorman-Rupp main pump plus a smaller electric drain pump.
On the problem with the washer I would take the control magnet assembly off the transmission and check for bent plungers, lose housing for the CM assembly, and I would also dismount the water pump to see if it is causing the problem. Other than these possible faults I am afraid that Gordon may be correct that something is broken in the transmission.
