I've checked the engine out and have found no vacuum leaks. This was traced back to a light film of corrosion on a coil wire. This causes the engine to flare up and then down again as the clutch cannot hold back the power of the engine.
It doesn't seem to cause a problem, but it's noticable and annoying. Only seems to affects shifts between 45-55 mph and only under light throttle. Refill the fluid and check for leaks. Somewhere around 45-55 mph, just before the transmission shifts up to 4th gear, there's a slight shudder that feels like it's coming from the transmission.

It is more plausible that the number indicates the torque handling capability in N-m, as 506 lb-ft converts to 686 N-m which could be rounded to 700 N-m. It really feels like something is slipping and catching and when a little power is applied, everything locks up the way it should. Remember to tighten in a crisscross pattern until firm, and then another quarter turn.
