Ó Copyright 2023 Ford Motor Company Stacy L. Balzer Ford Motor Company Operating Director P. O. Box 1904 Service Engineering Operations Dearborn, Michigan 48121 Ford Customer Service Division September 11, 2023 TO: All U.S. Ford and Lincoln Dealers SUBJECT: NEW VEHICLE DEMONSTRATION / DELIVERY HOLD – Advance Notice Safety Recall 23S54 Certain 2024-2025 Model Year E-Series and F-650/F-750 Super Duty Vehicles Equipped With 6R140 (Torqshift 6) Automatic Transmission Main Control Valve Body Or Transmission Replacement AFFECTED VEHICLES Vehicle Model Year Assembly Plant Build Dates E-Series 2024 Ohio December 6, 2022 through August 3, 2023 E-Series 2025 Ohio June 20, 2023 F-650/F-750 2024 Ohio December 12, 2022 through August 4, 2023 F-650/F-750 2025 Ohio June 27, 2023 through June 29, 2023 U.S. population of affected vehicles: 5,766 . Affected vehicles are identified in OASIS and FSA VIN Lists. REASON FOR THIS SAFETY RECALL In the affected vehicles, a casting defect in the transmission upper valve body casting may cause the main control poppet valve to get stuck in the open position. A stuck poppet valve restricts the flow of lubricant to the rear extension housing bushing, resulting in excessive heat generation in the bushing and erosion of the rear seal. This condition leads to transmission fluid leakage, noise and vibration. The increased vibration may result in a loss of torque retention on the abutment plate bolts. Once the abutment plate bolt torque is compromised, the park actuator may be unable to engage the park pawl into the park gear. SERVICE ACTION DO NOT DEMOSTRATE OR DELIVER any new in-stock vehicles involved in this safety recall. A complete Dealer Bulletin will be provided to dealers in December 2023, when it is anticipated that parts ordering information and repair instructions will be available to support this safety recall. IMPORTANT: Dealers should open a Repair Order (RO) only when a full dealer bulletin is published. Opening an RO against an Awareness or Advance Notice will result in warranty rejections against a recall. OWNER NOTIFICATION MAILING SCHEDULE Owners of record will be notified via first-class mail the week of October 30, 2023. PLEASE NOTE: Federal law requires dealers to complete this recall service before a new vehicle is delivered to the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up to $26,315 per vehicle. Correct all vehicles in your new vehicle inventory before delivery. Ó Copyright 2023 Ford Motor Company DEALER-OPERATED RENTAL VEHICLES The Fixing America’s Surface Transportation (FAST) Act law effective June 2016 prohibits a rental company from selling, renting or leasing vehicles subject to a safety or compliance recall. Please consult your legal counsel for legal advice. QUESTIONS & ASSISTANCE For questions and assistance, contact the Special Service Support Center (SSSC) via the SSSC Web Contact Site.

A stuck poppet valve restricts the flow of lubricant to the rear extension housing bushing, resulting in excessive heat generation in the bushing and erosion of the rear seal. This condition leads to transmission fluid leakage, noise and vibration. The increased vibration may result in a loss of torque retention on the abutment plate bolts. Once the abutment plate bolt torque is compromised, the park actuator may be unable to engage the park pawl into the park gear. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Should the abutment plate bolts become compromised, the transmission parking pawl may not fully engage when the vehicle is shifted into park, which may result in unintended vehicle movement if the parking brake is not applied, increasing the risk of a crash. Description of the Cause : Wear erosion on the upper valve casting die caused the bore to have a small amount of excess material deposited on the wall of the poppet valve cavity. Identification of Any Warning The vehicle operator may notice transmission fluid leaking under the vehicle. Additionally, the operator may hear a loud noise and/or feel a vibration while Part 573 Safety Recall Report 23V-625 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 that can Occur : driving. Involved Components : Component Name 1 : Transmission Component Description : E-Series Transmission with Extension Housing Component Part Number : LC2P-7000-FA Component Name 2 : Transmission Component Description : Medium Duty Fixed Flange with Extension Housing Component Part Number : MC4P-7000-VA Component Name 3 : Transmission Component Description : Medium Duty Fixed Flange with Extension Housing Component Part Number : MC4P-7000-XA Supplier Identification : Component Manufacturer Name : American Axle Manufacturing Address : 1 Dauch Drive Detroit Michigan 48211 Country : United States Chronology : On August 3, 2023, an issue pertaining to the transmission poppet valve was brought to Ford’s Critical Concern Review Group (CCRG) for review. On June 15, 2023, a commercial fleet customer informed Ford of a 2024 model year F650 truck with a transmission that had a fluid leak from the rear seal. On July 12, 2023, Ford personnel picked up the leaking transmission for analysis. Ford Engineering continued to review returned transmissions that exhibited similar symptoms. Through transmission teardown analysis, the CCRG investigation determined that a casting defect in the transmission upper valve body casting causes the main control poppet valve to get stuck in the open position. Part 573 Safety Recall Report 23V-625 Page 4 The information contained in this report was submitted pursuant to 49 CFR §573 Additionally, the CCRG team reviewed supplier maintenance records to identify when the casting insert was replaced due to wear. The CCRG requested measurements of the valve body casting in the area of the poppet valve on returned parts and confirmed that parts produced in the suspect time period were out of specification. Continued analysis of returned transmissions found that, in certain cases, some of the abutment plate bolts were either missing or loose. Through the transmission teardowns, there is evidence to suggest that a loss of park is possible, although this condition has not been reported in the field. As of Aug 22, 2023, there have been 95 warranty and field reports, received between March 24, 2023 and August 14, 2023, which are potentially responsive to this concern. CCRG also reviewed the customer usage from the warranty reports and noted that many were from rental vehicles . On September 1, 2023, Ford’s Field Review Committee reviewed the concern and approved a field action. Ford is not aware of any reports of accident or injury related to this condition. Description of Remedy : Description of Remedy Program : Owners will be notified by mail and instructed to take their vehicle to a Ford of Lincoln dealer to have their transmission inspected. If there are metal fragments found in the transmission valve pan, the transmission will be replaced. If metal is not found in the pan, the valve body and extension housing will be replaced. Ford provided the general reimbursement plan for the cost of remedies paid for by vehicle owners prior to notification of a safety recall in May 2023. The ending date for reimbursement eligibility is estimated to be January 12, 2024. Ford will forward a copy of the notification letters to dealers to the agency when available. How Remedy Component Differs from Recalled Component : The automatic transmission (LC2P-7000-FA, MC4P-7000-VA, MC4P-7000- XA) will have a valve body casting produced within proper specifications. Identify How/When Recall Condition was Corrected in Production : NR Recall Schedule : Description of Recall Schedule : Notification to dealers is expected to occur on September 11, 2023. Mailing of owner notification letters is expected to begin October 30, 2023 and is expected to be completed by November 3, 2023. Planned Dealer Notification Date : SEP 11, 2023 – SEP 11, 2023 Part 573 Safety Recall Report 23V-625 Page 5 The information contained in this report was submitted pursuant to 49 CFR §573 Planned Owner Notification Date : OCT 30, 2023 – NOV 03, 2023 * NR – Not Reported
