eror codes I have lots of error codes

You want to tell us what the error codes are?

I’m leaking tranny fluid like crazy. I changed the gasket

A timeline of events would be helpful on this end @Cindi_Smith.

@Cindi_Smith Details are necessary to get helpful answers . Just saying lots of codes is not enough and I guess the gasket did not stop the leaking.

before or after it started leaking?

On the side of the transmission is a component called the vacuum modulator.

Remove the vacuum hose from the modulator, and if transmission fluid leaks out, the modulator diaphragm has ruptured, and transmission fluid is being sucked into the engine.

What kind of transmission do you have? C4? C6?
