Hi.

I have a F-150 2001 4.6L v8

My transmission is a 4R70W

The specification for the capacities are 13 Quarts.

I wanted to change the oil of my transmission.

So I bought a new filter, Gasket and 15 quarts of Mercon V .

I unscrewed most of all the bolts and drained the pan. I was expecting at least 10-13 quarts to drain but to my surprise only about five total drained.

I changed the filter, the gasket closed up everything and replaced the missing fluid. I am now left with 10 quarts of Mercon V

Can anybody tell me why only about five quarts drained?

I found everything to be really straight forward and as uncomplicated as can be but for some reason i'm quite unhappy of the result.

 

The rest of it is in the torque converter and it is my understanding that some of the newer models did away with the torque converter drain bolt.

 

Only way to do it is to using a flush machine or undo a cooler line and let it idle pumping out all the fluid.

The 13 qts is for refilling from completely dry. Dropping the pan is just a partial drain. If you want to get more out next time. Drop the pan one afternoon/evening & finish the next day. It'll just sit there & drip,drip,drip,drip.

 

That should get you up to 5 1/2 quarts.

If you want to change ALL of the fluid, read this:
