Fixed: It was indeed a governor problem. I had installed the weights backwards in the governor shaft. The weight assembly needed to be installed with the snap ring facing outward.

Howdy! Just got myself a van with an A727 and reconditioned the transmission myself. I am having the same symptoms as TylerW. I know it's been 8 years, but if you get this, could you tell me how you ultimately sorted it out??
Thanks,
Wes
