On that note, I don't know! I'm just told that the converter has a drainplug on these!
I didn't think far enough ahead to figure out prefilling...I was just going to do it the old fashioned way...put fluid in until full, then start putting it in each gear to fill the journals...making sure the fluid level never drops too low...kind of like bleeding brakes I guess. Now you got me thinking though!

Hey question...how much are fuel pumps going for on these rigs? Hope it ain't $800 like our Yukon was!

There is a rubber plug on the bottom of the bell housing. Pull the rubber plug then turn the crank shaft either with a socket and breaker bar or I use a starter button to turn the engine over. What you are looking for is a square drain plug to line up with the hole in the bottom of the bell housing. Drain the fluid, it takes a while to drain through that drain plug. Put the drain plug back in then start filling the trans back up. I put in around 8-10 quarts then start it up and start checking it after running it through the gears. It takes I beleive around 15-17 quarts for a complete change. I wish all vehicals had a converter drain which I feel is alot better than flushing a trans,but if you keep up with the fluid changes it shouldn't become an issue.
