two oil looking warning lights on dash. one red one orange with wiggle line under it. whats, what?

I'm assuming red is oil & orange with the squggily line is transmission fluid. Ugh, sealed trannys suck. Well I'm out $100.

Red is your oil. The orange is more than likely coolent

The coolant might have a little thermometer symbol...depending on the year it may have a oil quantity..level, not pressure, warning

GM's have a red oil pressure light. If it's on - turn the engine off. Some also have a yellow oil level light. It comes on when the engine oil is 1.5 quarts low. Usually says Low oil or Check Oil. The Catera might be different.
