Have you pulled down a failed valve to see what the cause was? Harvey.

However, if I recall prorperly, I read somewhere that it was supposed to go full apply at launch. It has been my experience on other cars that duty solenoids go belly-up from sheer wear, due to the nature of their operation. Of course, contamination is always a huge possibility too.

Wait, the power is supposed to be transfered to the rear wheels at launch? Whenever it is wet and I floor it my front two tires will spin freely (bald tires) for about a full second to a second and a half before more power gets shoved to the back. Is this normal?

The other way it responds, is to a difference in the front to rear wheel speed. A small amount means the car is turning a corner, so a small amount of rear torque is applied. If the difference is large, (over 20%), the TCU will react by applying full torque to the rear wheels , this should be almost instantaneous and there should be no noticeable front wheel spin. If the front wheels do spin, as you say "for a second or so" there is a delay in the take up. This delay is not good as when the clutch takes up the front plates are already spinning faster than the rear clutch plates. This causes the clutch to act as a brake to slow the front wheels down to the back wheel speed. As you would realise this causes a lot of clutch plate wear. If everything is working right, the clutch never has to apply with plates spinning at difference speeds, as it will allways apply pressure before it gets to that state. What would cause the delay? A slow acting C Solenoid? may be. Worn clutch plates? may be. Slow acting or sticky transfer valve? This would be my guess. Harvey.

That may explain why about 6 thousand miles ago my front differential gears completely shattered into several pieces forcing me to rebuild the tranny before its time was due. I'll get this checked out as soon as I can. I'll also research how to get all the codes out of the ecu, tcu and any other ?cu that can give me any.
