im buildin a 87 gn for about 1k hp, maby 1000 miles a year of street driving.full weight car. 200r4 or 400 turbo? tips needed thanks
+1Neither use 4l80E with a manual transbrake valvebody.
Hey Dusty, is it possible to design a new convertor like a 9/11 or ?. Or is it just not feasable given the design of the 4l80?
Is it possible to have a TH400 where you can drive it like a normal car, have it shift itself, but also take it to the track and launch on the brake and manually shift it? Most I've seen talk about is a full manual valve body. Why is that? And whats with the reverse manual valve body?

We have had very good luck building 4L80Es and retaining lockup using converters from a couple of different suppliers. Even on some smaller combo using turbos.
