    Synth ATF

    I know I annoyed some people by reposting a topic about synthetic oil , well now Im wondering about synthetic ATF. my caddy has about 70K miles on it and I don't believe it has ever had the tranny fluid flushed. I want to get it done but the shop asks for something like 17quarts to flush the tranny. Is it worth it, or should I just do a regular non-synthetic ATF flush?
    What are contrasts between synthetic and non-synthetic ATF?

    Have the pan dropped and the fluid replaced. There is a plug that drains the upper part of the trans. Make sure that is drained.

    The extra cost of synthetic fluid could be worth it if you stress the vehicle (like high heat or towing) but if you replace it again at about 150k it probably isn't worth the extra cost.

    There have been quite a few threads on this.

    As stated above, DON'T flush it...just drain as much as is feasible, clean the filter and refill!
