If you want your SC400 to have low end response, you have to cut the wire mentioned this thread.

In stock form, line pressure is bled off in first gear, during shifts, and on downshifts to make the experience more luxurious. It also does this any time the ECU thinks power delivery would make the rear end squat.

This mod is totally safe because it make it drive like every other non-Lexus that uses this transmission. The trans is happier because it isn't slipping and wasting horsepower that should be reaching the wheels.

I was going to use a relay so I could switch the wire as needed but I like it so much it's just staying cut permanently.
