Drivetrain horsepower loss

There is a chart floating around the net on the popular HP loss through various automatic transmissions; I have to say, in an automatic that torque converters have the largest hand in the game of making power to the wheels...


Recently I did a th400 for my truck, used a 1800 stall converter for it; it was ok, a little slippery down low, ho hum... Started making noise so I tossed in a the new hotness Hughes has for stall towing converters to see if it made the noise go away, it didn't, turned out it was the filter wasn't fully seated.

BUT:

That converter makes the damn transfer case shifter want to twist out of the truck every time I look at the throttle; the 5,000 lb truck with a 350 wants to go INSTANTLY off throttle. HOLY PULL!

Totally different rig just from a quality converter swap. These days I've become a believer of being more concerned with a good build and a great converter, over how much bench racing tells me it eats power blah blah blah.
