Some would tell you 20%. No one can tell you exactly. Try figuring about 18% as a factor of loss.

Maybe 3.5-5%% less than a manual. Anthony Ulakovic on here made like 396-397 thru his M6 car.

Manuals are about 12% and the 4l60e is probably around 16-18%. Horsepower TV verified that a TH400 is ~20%... but thats a beefier tranny.

Good work......glad to see others put the effort in to find where the power is being lost. What stall speed and brand are you running?

Convertor was locked. Btw track #'s speak dyno #'s don't, I've dyno'd at a bunch of different shops and my #'s were all over the place. That should put down somce nice track #'s though.
