This is a very common problem, and it is something you want to address sooner than later. The frictions that are in that clutch pack dont take to slipping very well. Once they slip they are a little easier to slip the next time and so on and so on. When the converter locks up in OD the tranny dumps line pressure. This is why when you get on the throttle fairly quickly in od the tranny cant boost the pressure quick enough to prevent the slipping. (This is a condesned version of what actually happens) The fix for that is to keep the apply pressure up, which we are able to do with our valve body.

Converter flow valve knocks down mainline pressure anytime converter clutch is applied. No matter whos valve body you use it won't help with a stock converter and high horsepower.
That is right, but with one box or tuner on it say a 125hp increase the valve body is more than enough. We have quite a few customers in the 450hp range that are running our v/b with the stock converter, with no problems. The stock converter isnt that bad from the factory. Furnace braized fins fairly efficient stator. The big problem with them is the mounting feet for the bolts. On the stamped steel front cover the mounting feet are only welded onto the cover. They can cause flex in the cover and eventually a crack can form. This is quite commonly diagnosed as a front pump seal leak. A billet front cover is also the fix for that.

Mike please understand I am not trying to undermine you here, just add some more information to what you have already said.:beer
