Transmission Solenoid Pack for Ford 6F35 CV6Z-7G391-A

If your 2015-2019 Ford Escape, Fusion or Explorer, 2015-2018 Edge or 2015-2017 Taurus with the 6F35 six-speed is banging into gear, flaring between shifts, or dropping into failsafe with shift solenoid codes, this is the assembly most techs replace first. It is a remanufactured Ford CV6Z-7G391-A, the part Ford catalogs under the 7G391 solenoid assembly base number: the cast aluminum solenoid body with the shift, pressure control and converter clutch solenoids installed in their bores, tested before it ships. It is not a bag of loose solenoids, and it is built for the later CV-casting 6F35, not the early units.

What the solenoid body does in a 6F35

The 6F35 is a front-drive six-speed transaxle with no shift valves moved by springs and governors; every clutch apply is metered by a solenoid. The solenoid body is the upper half of the valve body stack. It holds solenoids A through E, the EPC (line pressure) solenoid and the TCC solenoid, and it bolts to the main control casting with a separator plate between them. The powertrain computer sends a varying current to each solenoid, the solenoid sets a pressure in its output circuit, and that pressure applies the matching clutch. Sonnax notes that the later 6F35 solenoid body added piston-and-spring dampers to the SSB, SSC, SSD and EPC output circuits to soak up pressure pulses, alongside the main damper on the 1-2-3-4 solenoid A circuit. When a solenoid sticks or a damper stops working, the clutch it feeds applies too hard, too soft, or late.

Symptoms that point to the solenoid body

• Harsh or double-bump engagement into Drive, or a clunk on downshifts
• Upshifts that flare and then catch, especially 2-3 and 3-4
• Delayed engagement after the vehicle has been parked
• Failsafe mode with the transmission held in one gear
• Shift solenoid circuit and performance codes in the generic P0750-P0770 range, line pressure control solenoid codes (P0960-P0962), or TCC codes in the P0740s
• Slips or flares that persist after the 3-5-Reverse clutch has been checked; the 6F35 is known for wave plate and 3-5-R clutch failures, and pressure problems from the solenoid side can mimic them

How to confirm it before you buy

Check fluid level first, hot and on level ground; a 6F35 that is a quart low will flare and set codes that look exactly like a solenoid fault. Then read codes and watch commanded versus actual behavior on a scan tool. Burnt fluid with friction material in the pan means the clutches are already damaged and a solenoid body alone will not fix the slip. Our guide to Ford 6F35 transmission problems walks through separating solenoid and valve body faults from the 3-5-R clutch failure before you spend money.

Fitment

This CV6Z-7G391-A unit is listed for 2015-2018 Ford Edge, 2015-2019 Escape, 2015-2019 Explorer, 2015-2019 Fusion and 2015-2017 Taurus with the 6F35. Those years fall in the Generation 2 and 3 era. Sonnax states that Generation 1 (casting numbers 9L8P or BL8P-7A100) and Generation 2 (CV6P-7A100) solenoid bodies are not interchangeable, so read the casting number on your old valve body and lead frame before ordering, or send us your year and VIN. The Lincoln MKC and MKZ also used the 6F35 but are not on this listing. If your unit is the early casting, look at our 6F35 solenoid kit for early units instead, and browse every 6F35 part on the 6F35 collection page.

Install notes

• This is an in-car job behind the valve body cover. Drain the fluid, unplug the range sensor and case connector, and remove the valve body from the case.
• The solenoid body separates from the main control with its own bolts; keep the separator plate and check balls in place, and inspect the plate for check ball damage.
• Torque all valve body bolts evenly to factory spec in sequence so the castings pull flat.
• Refill only with Motorcraft Mercon LV, then check level at the specified temperature.
• Every 6F35 solenoid body carries a strategy number and body ID on its tag and lead frame. Plan on loading the new solenoid strategy into the computer with a capable scan tool, then clear codes and drive the adaptive relearn.

If the clutches are already slipping, pair this with a 6F35 rebuild kit with frictions and steels, or step up to a complete 2015-2019 6F35 valve body with solenoids if the main control bores are worn.

Is this a full valve body or just the solenoids?

It is the CV6Z-7G391-A solenoid body: the cast aluminum upper body of the valve body stack with the shift, EPC and TCC solenoids installed. It bolts to your existing main control casting. If the main control bores are worn too, a complete 2015-2019 valve body with solenoids is the better buy.

Will it fit a 2012 or 2013 Escape or Fusion?

Not unless your valve body carries the CV6P casting. Early 6F35 units use the 9L8P or BL8P casting, and Sonnax states the two generations are not interchangeable. Check the casting number or send us your year and VIN.

Do I need to program anything after installing it?

Yes. Each 6F35 solenoid body has a strategy number and body ID on its tag and lead frame. Load the new solenoid strategy into the computer with a capable scan tool, clear codes, and drive the adaptive relearn, or shift quality will be off.

What fluid does the 6F35 use?

Motorcraft Mercon LV only. Ford's fluid chart lists Mercon LV for every 6F35 application. Check the level hot; a low 6F35 imitates a solenoid fault.

My transmission slips in 3rd, 5th and Reverse. Will this fix it?

Usually not on its own. Slips in those gears point to the 3-5-Reverse clutch and wave plate, a known 6F35 failure. Inspect the fluid for friction material; if the clutch is damaged it needs a rebuild kit, and the solenoid body is replaced alongside it.
