You can install a drain plug in the stock steel pans. ( I believe that your aluminum has that.) I install the drain in the side. Get an engine drain plug that's the same one in your engine. Get a short jam nut for inside.. Drill the pan. Install the bolt and nut without the bolt gasket. The nut just needs to be tacked in. The gasket on the bolt will be your seal. Be very careful to position the drain. As to miss the valve body, and filter of the trans. When you change your fluid. You can only get half of that fluid out. In this way you can simply change half out every year. Then change the filter every 40, to 50,000 miles. Fluids CHEEP. Transmissions aren't. Only reinstall the same type of fluid that's already in there. Bob Dunahugh

Ragusa pans all have drain plugs.
Since I cross the country at least twice a year, I drop my pan and examine
the bottom for metal particles.
When I do, I will need to determine if it will take me to the destination
and back.
I think I will start using oil analysis for the trans as well as the
engine oil.

There is no question a drain plug makes the process easier. However I'm of the opinion you should always drop the pan to check for teeth fur and
eyeballs as well as sevicing the filter

Chris. Yes. A good part of pulling trans pan is seeing what's on the bottom of the pan. And for most owners. Their talking every 60 to 80,000 miles. I'm at every 2 years of pulling the pan/filter. ( We've been running 12,000 miles a year. And just change fluid in the between the pan pulling years. Yes. I over do changing the fluid. But it's cheep. I rebuilt my trans myself in 2004. My GVW runs from a low of 17,000 to 25,000 lbs all the time. I think my fluid change scedule just maybe paying off. Bob Dunahugh 78 Royale 403

Another tip. If you are going to pull the pan, you need to lower the level of the fluid to the amount possible, if for no other reason, to avoid the
mess. Here's how. Go buy about ten feet of small clear plastic hose. Remove the dipstick. Insert the tube into the dipstick hole and push it to
the bottom of the pan, which will be slightly further than the length of the dipstick. Get the other end of the tube lower than the pan and ready to
put into your drain pan. Siphon by sucking until you see the fluid coming down the tube. put the tube in the drain pan and ensure there's still
fluid and no bubbles in the tube, and that fluid is (slowly) running into the drain pan. Go have a beer and watch a DVD - it doesn't siphon very
fast. When you return, ensure that several quarts of fluid have been siphoned out. Now remove the pan and you won't get fluid pouring out of the
edges of it.

Bob Dunahugh,
What are your transmission temperatures while pulling that heavy of a load? What transmission fluid cooler are you using? More than just the radiator
cooling I suspect.

I run a 3/8 size cooler steel lie to the radiator and air cooler.
The GM option was the 3/8 to allow easier flow of fluid.
We now stock the SS one that avoids the Hot exhaust by moving to the side.
