Transmission fluid check and service, with torque specs (per the Service Manual)

[wax87]

I'm posting this in the maintenance section rather than the transmission section because it's the servicing instructions for the transmission on the EcoBoosts. The revision of the service manual is 2021 so unless something drastic changes, it should remain current for a while for the 8F35's. If something does change and someone informs me of it, I will update the post accordingly.

I'll start with the how to fluid level check procedure:

The rest of the procedure for the fluid exchange is the same as the fluid level check.

Now the drain and refill procedure:

Pretty simple procedure. I'm sure you can skip the step that calls for using something like Torque to monitor the TFT PID (temperature), but it does need to remain at operating temperature during the procedure.

Hope this helps.

Do you have this for the Hybrid tranny?

Not sure if it was mentioned previously in this thread, but RockAuto stocks the 5qt jug of the recommended Mercon ULV. Search using XT125QULV, priced at only $24.79 currently. Even with shipping, this is probably way cheaper than buying individual quarts from a local store or dealer. I'm just approaching 24,000 miles and I bought all the fluids for the transmission, PTU and RDU. It was just over $90 for everything shipped.
