This is an interesting site that backs up Tjfly4pay's experience:

Makes me wonder what is the main cause. Is it excessive hydraulic drag or just mechanical inertia? Sounds like it is a lot of both.

I don't buy it, was his torque converter matched to his application? Really matched? Plus its a 518, they take more power to run, just like the 727. On that link, all I see is a ridiculously colored sales pitch. Lets let more chime in on the subject. Still doing my 42RH swap without batting an eyelash.

And this is why you use the 200R4, it takes the same or less power then a 904 does

The only reason that it makes sense to run a 200r4 is if your scared of chopping up your car. Everything else 42RH wins. Plus it's way cheaper to get into an a body. Way cheaper.
