I did a little digging & found that the transmission in the the 3's (and I believe the 4's) are the same unit found in some Ford Expeditions & all Ford Raptors. I called the local ford dealer and ordered a few variations to compare. I ended up using this pan - 9L3Z-7A194-A and filter 7L1Z-7A098-A. Then added a B&M universal drain plug to simplify future fluid & filter changes. Speaking of fluids, after much research I decided to take a "chance" with Motorcraft SP transmission fluid. I figured at worst it would cause the transmission to shift more firmly, which is based on the assumption that LR specs fluid for silky smooth shifts & Ford probably isn't as concerned. After almost 5k mi I honestly can't tell a difference - at all. Feels the same in every aspect.
The ford pan has a sump that extends downward, lower than the OE plastic pan so you will have to either trim & completely remove the heat shield. I decided to trim it. The heat shield bracket will also need to be modified, but it's a straightforward deal with a cutoff wheel or hacksaw.
I have just over $100 in parts & fluid into it. Not too bad.
You'll need;
New bolts (thinner pan flange) M6 X 1.0 - 15mm
Pan gasket (sorry, no part no.)
Pan 9L3Z-7A194-A
Filter 7L1Z-7A098-A
