if you have a 3200 stall converter and are driving on the highway continuously at 2800 rpm's, is the converter slipping until you hit approx. 3200. Doesn't that translate to extra heat for the converter and the trans.
While there will always be a percentage slippage in any non-lockup converter or a converter under the stall speed, however with a quality converter this is minimal.
Remember the converter only sees what's in front of it at that time. So if you make 350ft/lbs of torque at 2500RPM, that's what the converter sees. IF you make no sharp movements with the throttle, it will act accordingly. Flash stall is observed when you mash the pedal from a dead stop or mash it when cruising under the flash stall. My convertor is a 10" 3500, I run a GVOD and can't foot brake much past 1200rpm. IT buimps going into gear
