NO, do not flush it. Just drain and fill the fluid at 100k.
It's super easy to do it yourself.
Can you elaborate as to why? i am being told that the flush does not harm the transmission, and that with a drain and fill, you are not getting all the old fluid out, only about half, so you are mixing the new fluid with the old " burnt" stuff.
Please stop listening to a guy that wants to charge you $500 for a $20 job.
Thanks Okashira, the fluid alone has to be more than $20 though. he did give me all the costs, i just have them written down at home, it was $212 for just the fluid, said it would take two cases, use the first to flush out all the crap, and the second to fill.
the mechanic has in the past not charged us for parts he never used, he would give us a price, and when we went to pick it up it would be lower, when asked why, the answer was that he ended up not needing a part.
i have found that most mechanics that i have dealt with in the past would not have done that, so that is why i mostly trust him. but at the same time i want this car to last another 10 years and another 80,000 miles so i am very weary on which route to go. if i do a drain/fill, would i need to drop the pan and replace the filter?
my DW car a 2005 corolla has 140,000ish miles on it, and i don't think that the transmission has ever been drained or flushed, runs fine, but her inspection is coming up and now i'm afraid that the same thing will come up, she trusts the guy much more than i do.
