I would suggest a complete flush if the oil is burnt. I suspect your tranny may be running on the high side at some periods.
If you can spare the coin, try the PML tranny pan for added cooling due to it being aluminum and holding more fluid.
www.trailduty.com has them in stock.
Since your '03 requires DIII ATF you could also try Syn ATF, or just upgrade to the new GM D6 (Dexron VI) ATF.
