In agreement with the diag procedures above for checking in all shift ranges and double checking the throttle valve linkages from the carb down but if the frt pump was changed wouldnt it be wise to check all the pressures? Maybe no need to adj the t v stop min press but all these should be checked. Seems 2 guages needed since the Packard press ck work sheet compares pump press to others with specs of at or not less than 10 lb less... Packard guage set not nec- 2 trans press gages or 1 trans,1 oil pr should do. As a fan of the Twin and someone fascinated with the "direct drive" (lock up trq converter) I would hope those with more exp will add in as I only had hands on with hydromatics. I realize the rear pump was for push start ability but with 12 volt arriving and less need for that feature why didnt they eliminate the rear pump? How important is rear pump press and gov press to normal operation over 15 mph? How important are the fr pump and rear pump check valves to norm operation?
