Do not do a trans flush only a drain and fill. It will ruin your transmission.

Or you could spend ~$100 for the fluid (Rock Auto) and a couple hours of your time, and do it right.

Exactly - Did all of mine in a weekend.

It's certainly one of the easier vehicles to maintain, everything is very accessible.

250 for the RDU is criminal. It takes 15 minutes.

Those prices are insane. If you don't want to do it yourself or can't, find a local mechanic. There's nothing special about these parts or the fluid changes.

What quantities are you buying? My local guy will let me source the fluids, looks like the PTU is good with 1 qt, the RDU may need a little more than a quart (so a 2nd one), and a drain & re-fill on the trans looks like just over 5qts.

I did one Qrt for each and then got a 5 Qrt jug for tranny from rock auto.

Nice, I would go Rock Auto for sure then! Based on my research, checking the factory spec sheets, and talking to a local Ford dealer, you don't need a second bottle for the rear diff. 1 bottle of each gear oil is plenty.

I’ve seen a ton of conflicting information online about the fluid amounts, but that's usually because people confuse the total "dry factory capacity" with what actually comes out during a standard service. Just a heads up, I haven't physically done the service on my own Tremor yet (planning to soon), so definitely verify your levels as you fill!

Here are the spec capacities for a standard drain and fill:

• PTU (Front): The unit is tiny. It only drops around 13 oz. (1 Quart of 75W-85 leaves you plenty extra).
• RDU (Rear): The total capacity is 28 oz. (1 Quart bottle is 32 oz, so it fills it right to the brim with 4 oz to spare).
• Transmission (8F35): The total dry capacity is around 8.5 quarts, but a ton of that stays trapped in the torque converter. A standard pan drain-and-fill only drops about 4.5 quarts. (The 5-Quart jug of Mercon ULV covers it perfectly).

Here is the part number breakdown from my order if you want to copy them:

• MOTORCRAFT XT125QULV Mercon ULV; 5 Quart — $34.79
• MOTORCRAFT XY75WQL SAE 75W Disconnect Rear Drive Unit Fluid (1 Qt) — $33.79
• MOTORCRAFT XY75W85QL SAE 75W-85 Premium Synthetic Hypoid Gear Lubricant (1 Qt) — $25.99

These services aren't due at 40k, unless your vehicle has been subjected to severe service. Sounds like your dealer is scamming you. We just had our 5k oil change at 44 k and dealer said nothing about this.

I did RDU and PTU last weekend, maybe $80 total including the hand pump, if I had to guess and assume all the right tools including a lift I would say maybe under 45 minutes to perform. It takes longer to remove the cardboard protector 15 screws than anything else.
