So I have a 2002 Olds Alero with 166,000 miles on it. I bought the vehicle from a federal auction in 2004 when it had 49,000 miles on it. Although I have regularly had the engine oil changed every 3-5K miles (Moblie1 full synthetic), I don't actually know much about cars so I never had the transmission fluid drained until recently at 164,500 miles. There is no easy to check dip stick for the transmission, its apparently a sealed unit with a spot for checking fluid on the underside.
The shop wanted to do a full transmission fluid flush, but after I asked a question on this site regarding transmission flushes I opted to have them drop the pan, drain and fill. They said they put in about 7 quarts of transmission fluid. They actually recommended a transmission flush after another 6,000 miles (of course I'm thinking I could have just done that in the first place). I voiced my concerns about stirring up debris that would settle into the wrong places.
However I realize the first drop, drain and fill did not remove all the old transmission fluid. So I'm thinking I probably should have something done in another 6000 miles or so. The shop is saying that if I don't do the flush it will still be mixing old fluid with new. My question is, should I have another transmission fluid service in 6,000 miles and if so, is another drop, drain and fill the way to go vs a flush?
I'm sure I've been lucky to have not had any transmission problems so far, that may be due to the fact the I drive it very, very gently. I never speed off the mark from a stop and rarely ever drive over 70 mph. Almost all the miles on the car are freeway miles.
