Special Service Message 53465 - 2020-2024 Edge/Nautilus + Other Models & Model Years - Erratic Shift And/Or Fluid Venting - Engine Coolant In Transmission Fluid

[Haz]

SSM 53465 - 2021-2024 Bronco Sport, 2020-2024 Escape/Corsair/Edge/Nautilus/Transit Connect, 2022-2024 Maverick - Erratic Shift And/Or Fluid Venting - Engine Coolant In Transmission Fluid

Some 2021-2024 Bronco Sport, 2020-2024 Escape/Corsair/Edge/Nautilus/Transit Connect and 2022-2024 Maverick vehicles may exhibit erratic shifting and/or a transmission fluid venting condition. If during the preliminary inspection the transmission fluid is found to be a foamy pink color, this may indicate possible cross contamination of engine coolant and transmission fluid due to an internally leaking transmission fluid cooler assembly. When repairing or replacing the transmission assembly for an internally leaking transmission fluid cooler assembly, use causal part 7869 and applicable labor operations in Section 07 of the Service Labor Time Standards (SLTS) Manual.

This does show up against my hybrid so must be non hybrid models

@Bunky: You are correct that the transmission cooler for the 2024 Nautilus Hybrid's HF55 Automatic Transmission is a liquid-to-air heat exchanger that presents no opportunity for engine coolant/transmission fluid cross-contamination...

 

 

...which is mounted onto the front of the (engine coolant) Radiator...

 

 

 

The causal base part number cited in SSM 53465 -- 7869 -- resolves to the Transmission Fluid Cooler used with the 8F35 transmission...

 

 

...which is mounted beneath the 8F35 Transmission...

 

 

 

Ford's online parts-selling site designates the 7869 Transmission Fluid Cooler as fitting the models affected by SSM 53465, though not for all listed model years...

Based upon its appearance and the cross-contamination failure mode it's described as producing, the 7689 Transmission Fluid Cooler is a fluid-to-fluid heat exchanger.

 

And finally, the Transmission Fluid Cooler for the 8F57 Automatic Transmission is an integral part of the A/C Condenser, and as a fluid-to-air heat exchanger, it provides no opportunity for engine coolant/transmission fluid cross-contamination...

 

 

 

It's fair to say, it would've been nice if the Special Service Message included the affected vehicles' engine/transmission combination(s).

 

Good luck!
