I have a TH 400 auto box with change kit and standard torque converter which works great excepting at high speed when on the track and changing down from 3rd to 2nd gear.

Approaching a corner under heavy braking and then manually slotting it into 2nd gear at a safe rev the rear wheels lock for a fraction of a second giving a distinct chirp from the tyres and unsettling the car ever so slightly. Other than waiting to change when one comes off the brakes, which could be risky in it's own right as I am generally in the turn by then, do any of you suffer from similar problems and how do you mitigate them?

At the moment I just live with the problem but maybe one of you has a solution other than the obvious one of putting in a manual box.
