fluid change question

[lght1]

Hi

I am new to the Powerstroke world with a purchase of our southern L99 F-250 4x4.

After servicing the engine, I would like to do a pan drop tomorrow and am wondering how many quarts of fluid will I need?

I believe this truck calls for Mercon V , is that right?

I also discovered that certain trucks had a shallow pan.. is that just for 2wd models?

Thanks in advance.

Your transmission is a 4R100 4x4, if completely empty the trans will hold 18quarts. however if you dont drain everything (TC, Lines, VB, ETC) it will only take around 14.

When you drop the pan, it can just be wiped clean, and check for metal shavings stuck on the magnet. the gasket is reusable for the pan also! hope that helps some

Shallow pan= stock Pan
Deep pan= after marker

are you just dropping the pan and changing the filter or doing a flush?

I would just flush it instead of trying to guess what fluid is already in there. I think the pan itself held around 6 quarts when changing the filter too. Don't quote me on that it was almost a year ago.

Hi

We did a pan drop and filter change. It was fairly straight forward and thankfully, the old fluid was very clean..even fresh.

AMSOIL synthetic is bullet proof. No worries about the oil breaking down fast with heavy towing loads

with a compleat flush it will take 18 quarts
