    Hi there,
    It would be great to count on your experience regarding Automatic Transmission.

    Year: 1994
    Miles: 90.000

    There´s no problem with it, just want to take good care of it.

    It´s OK anly change fluid and filter?
    How do I know the transmission model so I can buy the parts?

    Thanks

    Did you just buy the truck? If so, Do you have records of the maintenence and repairs done by the previous owner?

    In my experience, automatic transmissions that have went over 75,000 miles without a filter and fluid change last longer by not adding new fluid. What happens is the new fluids have detergent in them that causes the old material and debris to wash out to the pan. Then that material pluge the screen and ruins the transmission.

    If you do start replacing the filter and fluid, I suggest getting it flushed and replace the filter 2 times at 2500 mile interval, then regular drain and filter 4 times at 5,000 mile intervals. Then start servicing again nomal intervals.

    I have seen many transmissions run 250,000 miles with no services done, as long as the truck is not towing heavy weight.

    Thanks Will,

    I don't have any record, but so far it Works good, the only time when I feel something is when I stop the truck fast. I already change the transmission support. Kind it happen when pass from 4th to 1th at once because when I stop it in a long distance allowing the transmission to shift from 4th to 1th passing 3th and 2d nothing happen.

    Why do you think this could be?

    Is hard to make a video because it's when you're driving it and it feels like a little push.

    No, is like there were a problem with the transmission support, but it's new.
    And it happen only when pass from 3d or 4th to 1st stopped, running it's doesn't move
