Quarts needed for 4r100

I am planning on just opening the plug on my 4r100 and refilling with new fluid. Does anyone know how much this trans takes if I just refill it?

I have the hughes alum pan that holds a couple quarts more, but I can do the math if you know how much yours takes with a stock trans pan.

Thanks in advance

I dont think you can just open a plug on an automatic trans and expect it all to drain out. You can do a pan drop and probably would need 3-5 qts to refill it.

Yes, you can just pull the plug on the auto trans pan then remove the whole tranny pan and replace the filter. 6-7 qts.

I know it won't all come out. I am going to just drop the plug every 20,000 miles - I am using Mobil 1 Synthetic and eventually it will all be mobil 1 in there. I will change the external filter by the water to oil cooler in another 20k.

Thanks

Well i guess ford did something right on these trucks finally lol. For some reason i thought you meant you were going to try and pull some kind of plug on the side of the trans and expect it to drain, thats why i was like wtf? lol All my other fords never had trans drain plugs. Bronco's and various ford cars.

The 4R100 fluid capacity is 18 or so quarts. When you drain the pan, you're only getting about 1/3 of a fluid change.

Do you really think he waited 17 YEARS for that incorrect information?

The 4R100 holds about 18 quarts of fluid. If you only drain the pan you'll get 5-8 quarts out.
