What is the Power Light on the dash

The "Power" light on the 4EAT serves two purposes.
1) As Keith alludes to, it indicates the transmission is in a special mode
where it holds each gear to a higher RPM than normal.
This mode is invoked by the speed at which the throttle is depressed.
Stab the loud pedal quickly and the power light should light.
Hold the pedal down and the shift RPM will be increased
(I believe it also increases the hydraulic line pressure in the transmission shift circuits)
2) The "Power" light also serves as a check for the operating components of the electronic controls.
If the TCU (Transmission Control Unit) detects a problem with one of these controls,
it will flash the light upon start up. The TCU can be put into a mode where it will flash the light to indicate the trouble.
The "Turbo" light illuminates any time the intake manifold is at a positive pressure.
(It also indicates the ECU is in the run rich mode, ignoring the 02
sensor and adding fuel to cool the combustion process.
Hope this helps

I have another question. When i accelerate out of corner, the inside front wheel starts to spin and then there is a big jerk and the car feels more solid. Is something happening in the rear drive line as well?

I believe this is what you are feeling
