2006 Ford Five Hundred Question: CVT - fluid replacement service



, Somersworth, NH, February 14, 2011, 07:50

A Ford dealer said that the CVT fluid only needs to be changed ever 90,000 miles, but Ford's maintenance schedule appears to indicate a 60,000 mile drain interval...who is correct? Considering the cost of the change @ $200+, 90,000 miles would certainly be preferred. Also, how difficult is it to change the fluid...I was quoted around $10/qt and around $20 for the filter, so that would be a big savings.
The dealer said they use a special flushing machine for the CVT...is this true? I know this is true for regular transmissions...Thanks

    Flush method - same as other transmissions.

    I am showing 60,000 miles for the fluid replacement interval on the CVT.

    Also - When carrying out a fluid change interval, the installation of a new high-pressure case filter and seals is required.

    This is different from the typical transmission pan and filter. Do not change that for the normal interval.

    I know this is very confusing...to sum up:

    Have the transmission fluid flushed with the appropriate CVT fluid at 60,000 mile intervals. Replace the high pressure case filter and seals at this time also concurrently.
