I have a 2007 F150 STX Supercab 2WD with the 4.6L V8. I plan on dropping my pan and just replacing the fluid that is in it. My question is, approximatley how much fluid does my pan hold? Is a Mercon V good for the new fluid? Also, on the pan it says the gasket is reuseable. I have never seen that before. Will it work okay?

 

I think the pan holds around 5-6 qts, but not sure. I have a drain pan that has qt markings in it which comes in handy for stuff like that.

Just me personally, I am not a fan of replacing just what's in the pan. The pan holds about 1/3 the quantity of the whole system. I like to swap out all of mine. But like I said, that's just me.

My personal recommendation again...if you're only going to do what's in the pan then I'd go with Motorcraft Mercon V. I wouldn't go with a quality synthetic (like Amsoil ATF) unless you were going to swap it all out.

Your gasket is definately re-useable. I've re-used mine three times in almost 6 years/80,000 miles and never the slightest hint of a leak.

 

I would love to have everything changed but since I am doing it myself I figure changing whats in the pan a couple times will be better than nothing. I am going to change whats in the pan and then run it for a good 5k miles and then do it again. I will do this about 3 times and then hold off for another 20k or so miles.

 

You can flush the whole thing yourself at home. Do some searching on here for "fluid flush" or "tranny flush", things like that. It's been written up a few times how to do it at home.

 

OH, I didn't know that. I'll look it up right now. Thanks.

 

The gasket is reusable. Consider changing the filter if you drop the pan. Plan on 5 quarts to refill. Any fluid approved (or recommended) Mercon V will work. With your truck being an 07 a pan drop is fine, no need to flush. In fact, a drain/refill/new filter every 30K is a great maintenance plan.

An oil extractor or hand pump makes dropping the pan much less messy by emptying the pan of fluid first and is a great way to do drain/fills without dropping the pan.

Installing a drain plug in the pan makes drain/fills easier than changing the engine oil. If you're pulling the pan off installing a drain plug while its off is the way to go.

 

Did my Fluid change today. I ended up getting about 4.5 quarts out so thats what I put back. In the pan was the small yellow looking plug thing. Anyone know what that is?

 

That is a plug used by the factory for the fill stick that gets knocked into the pan. You don't need it.

Ahh I see. I ended up keeping it in the pan because I thought it was some type of floaty thing. I will get it out on my next fluid change in 5-10k miles.

 

Here's the fluid change instructions that I use:

That's funny you put that back in the pan!!

 

I agree!
