Im sure this question has been asked but I can't find it...i took my 04 grand cherokee, 4.0 in for a tranny flush, mechanic charged me for 12 qrts of fluid. Don't they only hold 4 to 6 qrts? I have not paid him yet, just doesn't sound right to me.

Flushing a transmission does use fluid as well. Ask the mechanic to explain the costs to you.

A transmission flush machine will not even let you start doing the job till there are 12 quarts in the machine (does change for different machines) A real flush uses more fluid then it takes to fill in order to rinse the inside. This way you get as many contaminates out of it as you can.

As the others have said 12 quarts sounds about right. WJ Jeeps has 10 quarts listed for the over haul. So they basically pulled out all of the old fluid and put new fluid in. Probably lost a little somewhere in the process and the 10quarts is just kind of a guesstimate. The 4-6 quarts is if you just drop the pan as some of the fluid hides in the torque converter and a few other places.
