I have drained the transmission fluid and do not know how to refill the fluid again.
How can I refill my transmission fluid because I have no dipstick? on 2005 Ford Explorer
A beautiful design by ford! not. on the bottom of the pan remove the t30 plug in the center of the large nut.napa auto parts has a fitting part # 90-547 that will screw into the place where you removed the torx plug and you will need to get a fluid pump that will screw to the top of a 1 quart trans fluid bottle.Iusually force 1 quart in and then start it up and optimal temp for filling is 140-160 more or less.You can improvise with whatever you can as long as you can get the fluid into the pan,but this is how it is done the easiest.
bmdouble is correct again fords better idea
