# Service bulletin SSM 48913

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin

## NHTSA's summary

Some 2020 Transit vehicles equipped with a 10R80 automatic transmission and under 8,000 Km \(5,000 mi\) may exhibit a harsh engagement into DRIVE and/or REVERSE with or without an illuminated malfunction indicator lamp \(MIL\). This may be due to sticking main control valves. A new Ford Diagnosis and Repair System \(FDRS\) Transmission Accelerated Main Control Break\-In routine has been developed to aid in freeing up sticking main control valves. This routine has been added to the Workshop Manual \(WSM\), Section 307\-01.

- [TSB 26\-2226](/bulletins/11032697.md), 2026-05-14, Service bulletin: POWER TRAIN. This bulletin supersedes 26\-2046. Reason For Update: update the parts list to change the claim quantity of the C clutch friction plates \(HL3Z\-7B164\-A\), C clutch steel plates \(HL3Z\-7B442\-F\), D clutch steel plates \(HL3Z\-7B442\-D\), add the rear driveshaft flange CV joint\-to\-pinion flange cup bolts and retaining straps \(LK4Z\-4B496\-B\) for Transit, and update the parts description for the transfer case fluids applicable for each vehicle line. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: \* Harsh engagement \* Delayed engagement \* Harsh shift \* Delayed shift \* Illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTC\) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module \(PCM\) or transmission control module \(TCM\). This may be due to PCM software and/or axial movement of the CDF clutch cylinder \(7H351\) sleeve causing hydraulic circuit

- [SSM 54592](/bulletins/11029081.md), 2026-02-27, Service bulletin: POWER TRAIN. For 20172026 vehicles equipped with a 10R transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, located in Section 307\-01 \> Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements \(N\>R, N\>D, R\>D, or D\>R\) should be noted. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article.
- [TSB 26\-2046](/bulletins/11028832.md), 2026-02-17, Service bulletin: POWER TRAIN. This bulletin supersedes TSB 25\-2611. Reason For Update: Change the part number for the transmission fluid heat exchanger bolt \(Expedition/Navigator\) as well as change the claim/package quantities for HL3Z\-7B442\-F and HL3Z\-7B164\-C. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: \* Harsh engagement \* Delayed engagement \* Harsh shift \* Delayed shift \* Illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTC\) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module \(PCM\) or transmission control module \(TCM\). This may be due to PCM software and/or axial movement of the CDF clutch cylinder \(7H351\) sleeve causing hydraulic circuit leaks.
- [TSB 25\-2611](/bulletins/11027124.md), 2026-01-06, Service bulletin: POWER TRAIN. This bulletin supersedes TSB 25\-2474 for 3 Part List corrections. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: \* Harsh engagement \* Delayed engagement \* Harsh shift \* Delayed shift \* Illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTC\) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module \(PCM\) or transmission control module \(TCM\). This may be due to PCM software and/or axial movement of the CDF clutch cylinder \(7H351\) sleeve causing hydraulic circuit leaks. NOTE: If internal transmission service is required to address a concern detected with the CDF clutch cylinder following this article, technicians should carefully inspect and replace other transmission components and flush transmission fluid cooler only as necessary to confirm proper function. Add a new line to the repair order to document any additional repairs
