I found an article searching "4f27e" in google. They built a race trans for a zx5 that they were going to turbo.
They uoed the line pressure about 5% mechanically because they didn't want to get in to the ecm. Write of story claims it made a big difference in the shifts.

Everything else I read is people complaining about the low line pressure of these transmissions. I've only built stardards lately and mostly big CDL ones. I haven't onpened a ATX trans since the 700r4's
