? about CEL and horsepower

Ever since the 5-speed swap the Check Engine light has stayed on.
I have pulled the codes and all are auto tranny related. My question is:
Will the computer be robbing me of horsepower if the CEL is on? or is it not relating the trannys faults with adjustment to the motor?

Nope. No power loss. the ECU will only severely reduce power when the CEL blinks, indicating a major problem, like mis-firing. But then, you probably wouldn't need a CEL to tell you that
