Picked up our CMAX Energi yesterday from our local Ford dealer service department after the repair. They had it for about 8 days. The eCVT failed with 63K, and mostly electric miles. The build date was 12/22/2012. They reported that the differential and transfer shaft bearings were pitted, and performed TSB 18-2328 to replace HF35 transmission assembly. Several parts were included in the invoice including brake cleaner, sealant, and anti-freeze, but ATF wasn't listed. I hope they didn't put the old stuff back in.
I believe the replacement HF35 transmissions already include the automatic transmission fluid (sealed unit).
The invoice of my HF35 transmission replacement back in Nov 2017 (per TSB17-0039) included 5 quarts of what I believe to be engine oil. It was listed after Brake Cleaner and Anti-Freeze as "5 XT*10 QLVC OIL- AUTOMATIC TRANSMISSION".
I just hope Ford fixed the known bearing issue in the replacement transmissions so it does not re-occur. So far, my new transmission has 15K miles on it and is as quiet as the day I bought the vehicle in 2013.
