I took mine to a shop for a flush and filter change. Costed me about $240 all said and done give or take. the '03 (and other) denali's have a big transmission reserve and i believe they take approximately 16 quarts of fluid in the system. the trans fluid is around 7 a quart i believe, and I recommend a flush to replace all the fluid with new fluid before changing the filter so that when you change the filter out, you are running new fluid through it. I don't know how to flush the system without their special tool that straight swaps the fluid as the ****** is running, so that will have to be done by a shop anyways. As for the filter swap, I believe the filter is about $29 and you'll need approx 7-8 quarts of fluid to replace when you drop the transmission pan.

All in all, in fluid alone you will be spending approximately $175. $29 for a filter. let the shop make a few bucks and have it done by pros. I know they get discount on the fluids, but I figure I still spent $35 more than doing it myself for an hour or two of work. Not a horrific deal to be honest.

If you have your owners manual, there is a section containing the capacities for all fluids. You may also simply check your fluid level, with a running motor and warm transmission. If the stick indicates add, start with a 1/4 quart and work your way up. Unless there is a problem with the trans, there is no real reason to ever add fluid unless your are flushing the transmission.

This tranny has approximately 13 quarts of fluid. Just dropping the pan and replacing the filter will yield about 5 quarts or so, with the balance still sitting in the torque converter. I recommend just doing this instead of paying someone to power flush the system. There are debates whether or not this method will damage the tranny. When I did it, I got around 6-7 quarts out of it. Use GM's new transmission fluid Dextron VI. It's much better than the old stuff. GM starting putting the Dextron VI in 2009 and newer vehicles. Make sure you know what size your pan is, there is a shallow pan and a deep pan, the deep will have a step in it, the shallow will be completely flat.

There is another way to get rid of all the fluid, but it's very time consuming and difficult if you've never done one before. Involves disconnecting the transmission fluid cooler line at the radiator and having the pump inside the tranny pump out all the fluid for you.

Is it a 3 speed or a 4 speed. Can you tell where the leak is coming from. You need to add until it reads full on the dipstick when it warm and running.
