    I am looking to drop the pan and change the transmission filters on the 545RFE 5 speed transmission. Does anyone know how many quarts of ATF+4 I need to replace what I drain? A search online looks like I need 8 quarts but I want to make sure. Thanks.

    Have 8 on hand.
    Buy filter kit with a pan gasket. Use dry whichever one you get. The holes in the gasket are made such that they hold the bolts in place during assembly. No need to glue it in place. I have had 100% success with both cork and rubber gaskets.

    I would measure the amount of fluid that drains from the transmission after pan removal. Put that exact same amount of fresh fluid into the transmission. Run and then check fluid level and adjust accordingly.

    Link discusses replacement fluid quantity.

    5-45RFE Fluid change capacity (at https://www.dodgetalk.com/threads/5-45rfe-fluid-change-capacity.131547/#:~:text=The%20545RFE%20tranny%20hold%20a,(5.5%20qts)%20for%202X4 ).

    Does the converter have a drain plug?

    There hasn't been a drain on a converter for many decades.
