Flush or Filter?

[robertwhite]

Truck has 108K. Don't know if fluid has ever been changed, but truck was serviced at Ford for numerous things so it might have been.

Should I just get the filter kit for $20 and pick up a boatload of Mercon (don't know the capacity)

or

Do I take it to the tranny shop (well respected) and have them flush it for $150?

Problem with the flush is that I will not know if there were any metal shavings in the pan as I don't believe the pan is dropped during a flush.

Thoughts?

Don't flush it. You can use the internal pump and replace all of the fluid. You can google 4R100 fluid change and find the procedure. Good luck. Piece of advice....the tranny must be warm before you start or the recycle valve will stay closed and it will spit out the back connection! Don't ask how I know!

Any idea as to how many quarts of Mercon I will need?

Just get the filter, std fluid 8 qts and change it Don't need any fancy fluids and at 100K+ I wouldn't change to Amsoil. Trans fluid.
