Thank you for your replies. I will test the modulator. It was my understanding that if the vacuum modulator was failing I would experience slippage in all gears and any shifts that did occur would be rather hard. I initially put a flawed valve body on the back burner as I found myself with a very clean oil pan. I imagined that if the valve body was in some way impeded then something would have had to be responsible for such obstruction and some of this debris would be present in the pan. When I refilled the transmission I also added some Trans-X in an effort to free up any unwanted and troublesome elements within the transmision. I contacted German Star and they have one available for $275.00. I have never swapped a valve body. I will conduct a search to dtermine the nature of a valve body swap. Is there anything that immediately springs to mind as particularly challenging about such an operation?

I believe we are correct regarding the governor gear. I do not think there would be any upshift at all if it has been sheared off. A pressure test should bear this out. I understand that upon inspection, if you can rotate the governor by hand the gear is damaged. Will a pressure test also be able to relieve the B2 piston of any responsibility for the maladies that I am experiencing? Thank you again for your help and I apologize if any of you gentlemen get stuck driving behind me. 20 m.p.h. will try any man's patience. With your kind efforts to assist me I believe I will be back up to speed soon. Cheers.
