My 2008 Aveo sedan has 111,000 miles, and the transmission fluid is a light brown. I've read up on changing the tranny fluid by dropping the pan and changing about 2 quarts at a time, but I'm just not real keen on pending time under the car any more.
A "Jiffy Lube" - type place near me that I use for oil changes has a transmission flush service for $129. They say it isn't pressure - just fluid replacement. And it takes about 1/2 an hour. I've read several posts here on the various "compatible" fluid type, so it would be important to nail down exactly which one they would use, or if they would let me bring my own fluid.
 Would you consider something like this at this price? Assuming it includes 6+ quarts of the correct fluid and a new filter?
 In one thread (http://www.aveoforum.com/forum/f82/t...72/index2.html) post #14 mentioned the residual fluid in such a machine contaminating the new fluid of a different type. Would there be enough residual in such a machine to worry about this?
