having trouble with the trans warning light coming on, Holden seem to think its the oxygen sensor, I have headers and a big bore that was on the car when I got it. Any ideas of ways around this problem?

I assume mean check engine light. When that light comes on it logs an error code, did Holden check for codes or just offer an opinion? Finding out what code it is will help us to help you.

That light is the check engine light but don't feel dumb because I didn't know what it was called the first time I saw it either. Holden should have told you which code it was but they can be pretty secretive sometimes. Has the light come back on since they reset it?

yep comes on and off. car running fine though
I would go back and ask them which code it was, you did pay them after all (well I'm assuming you did since they don't usually do things for free). Once we know what the code number is we can probably advise you better.
