Just had my trns freshened. 727 behind motor in sig. the trans guy told me that the high gear (3rd) clutches were ok but glazed. He said every high stall converter with a high hp motor on the street glazes the 3rd gear clutches. His reasoning was that the converter is stalling at 3500 rpm and your cruising at 2000, so your always slipping, causing heat and glazing the clutches.

Not wanting to argue with him, I wanted to understand this reasoning more with you guys. I don't necessarily agree with the theory, unless the heat in the fluid around the clutches, not in the pan, gets hotter due to the slipping converter?
Could it be that there isn't enough line pressure at low rpms?
Does the slipping converter effect line pressure?
What do you guys think?
