I'm guessing you've got the 4L60E, automatic transmission. Check to see if it's overfull (engine warmed up and running, move the shifter through all the gears, then check the dipstick level in Park). It can also blow oil if the transmission is overheating or the tranny oil pump is bad. At that point you'd have to get a shop to verify either of those conditions.
