I have a 1999 chevy tahoe, LT v-8 A/T. I am a newbie at car stuff. I just changed mytransmission fluid in my accord and would like to change it in my tahoe. Ive searched the forum but cant find any help. Can someone give me instructions on how to change the transmission fluid? (I think i found the drain plug, but does my truck have a transmission fluid filter I need to change too?) Please Help, thanks!

You just LOVE outsourcing don't you engine2! Pretty much yes, you do have a tranny filter you should change. You also have an access hole to drain the torque converter too. It's pretty much just unbolt the whole trans oil pan take out the bolts that hold the filter and pop the new one in. Put the new gasket on the pan after properly removing the old gasket and the remnants. Fill with the trans to capacity (I BELIEVE could be 6-7 quarts). I'd leave the torque converter alone if you don't feel too mechanically inclined.
By dropping the pan and changing your filter and that fluid, your only getting about half of the fluid. Still something great to do, but I preffer to do it all. First I'll drop the pan and replace the filter and clean the pan. I'll fill it up to capacity. Then I'll take the transmission cooler line that goes to the radiator off. I take the top one off, and believe it or not, it comes out of the radiator at the top. I learned this the hard way. With a hose attatched to the output of the radiator and routed down into a bucket with 2qts marked off. Have somebody watch the bucket and get in and start the truck and begin to slowly put it through all the gears. As soon as the bucket gets close to 2qts, have your buddy yell, then shut it off. Put 2qts into the fill tube. Keep repeating until you at least replace all the fluid, or until it is clear fluid coming out. Be sure to check the levels after driving a bit.[/align][/align]Then again, jiffy lube only charges $100 for the fluid swap. This doesn't include changing the filter. They say you don't really have to do that. I don't trust those yahoos, so I do everything myself. Plus you can put a quality fluid in there. I use Amsoil ATF.[/align]

I figured the pictures in the chilton manual would guide him better. Plus those manuals have just about every maintainence item you can think of so you dont have to outsource. While these manuals may not be as good as the factory service manuals ($100+ for a typical 3 volume set) at $10-$15 they are a pretty good bargain.
There is no "access hole to drain the fluid from the torque converter on the 4L60E tranny in the 1999 Tahoe.Here are the instructions from the GM Service Manual:
