Code 24 and a th350

I was driving tonight and I got a code 24.

1ST time I ever got this code, and the wierd thing is I have a th350 that has been in the car for over a year!

I have a 91 GTA - tpi

Would this code affect the performance of the engine?
How do I make this code go away?

I am guessing I do, I used to have a stock car with a 700r4 before.

It's not hooked up, right now i have no speedo.

What puzzles me is why it took a year before the SES light came on?


Acceleration from a 7004r to a th350? I'm not sure b/c I changed my whole combo.
