Hum... that's an electronic shifting transmission which I'm not up on. I assume the same things apply to it that apply to regular torqueflites but since I haven't worked on any electronic units I'm not really sure. Could just be a pressure switch giving false readings to the computer and in turn the computer is lowering the line pressure too much. Do a search for duster346 and pm him. That's Chris Andrews and he's the man on transmissions. I bet he'll know exactly what to do. Sorry I couldn't help more.
