5R110W Transmission Solenoid Kit, 3C3Z-7G383AB

Searching for Ford part number 3C3Z-7G383AB usually means one thing: a 5R110W TorqShift that has started flaring between gears, engaging late, or setting shift and pressure control codes. This remanufactured kit covers OEM numbers 3C3Z-7G383AB, 3C3Z-7J136AA and 3C3Z-7J136AB and replaces the shift and pressure control solenoids in the solenoid body. It is listed for 2003-2006 F-250 and F-350 Super Duty trucks, the 2004-2005 Excursion with the 6.0L, and E-250 and E-350 vans from 2004 on, gas or diesel.

What these solenoids do in a 5R110W

In the 5R110W, the solenoids are the shift control. There is no stack of shift valves behind them. Each clutch except the forward clutch gets its own variable-force solenoid, and the computer sets the apply pressure of that clutch by how much current it sends. PC-A sets line pressure, SSPC-A through SSPC-E feed the coast, overdrive, intermediate, direct and low/reverse clutches, and a separate solenoid controls the converter clutch. A solenoid that responds slowly or leaks therefore shows up as a bad shift on exactly the gear change that clutch handles.

These part numbers date from the start of 5R110W production, so they matter most on the early trucks. A 6.0L that has towed for years puts a lot of heat through the solenoid coils, and the early units also lived with the original serviceable canister inline filter, which many owners never changed.

Symptoms of worn solenoids on early TorqShifts

• Harsh or late upshifts, or a slip and rpm flare between gears under load
• Slow engagement into Drive with Reverse feeling normal
• Limp mode, sometimes with the Tow/Haul light flashing
• Codes such as P0756 for the overdrive clutch solenoid, or P2700 through P2704 apply time faults on elements A through E
• PC-A codes P0752, P0753 or P0973 when line pressure control has a problem

How to confirm before buying

Pull codes and note which element or solenoid they name. On a 6.0L, check the harness and PCM connector before you condemn the parts. One documented 2005 F-350 set a string of PC-A codes because diesel from a leaking water-in-fuel sensor had wicked up the harness into the PCM. Also ignore old advice about the pressure switches on 2003 and early 2004 bodies: the computer on these trucks was never programmed to monitor them, and Ford deleted them in late 2004. Then drop the pan and test each solenoid for resistance and a free-moving valve. Our 5R110 shift solenoid guide covers the full bench test.

Fitment

The listing names these applications: 2003-2006 F-250 and F-350 Super Duty with the 5.4L, 6.0L or 6.8L; the 2004-2005 Excursion 6.0L; 2004-2011 E-250 and E-350 with the 6.8L V10; 2004-2010 E-250 and E-350 with the 6.0L; and 2009-2011 E-Series with the 5.4L. Not every one of those engines got a 5R110W in every configuration, so confirm the transmission tag says 5R110W, then match the part number on your old solenoids or send us your year, engine and VIN. If your solenoid body itself is damaged, the 5R110W valve body for 2003-2010 is the assembly to look at, and the full range of parts is on our 5R110W collection page.

Install notes

• Drain the fluid, remove the pan and filter, unplug the internal harness and remove the solenoid body.
• Replace the solenoids one position at a time and seat each with a new, lubricated O-ring. They are keyed to prevent misassembly, but working one at a time keeps the harness clips in place.
• On an early body that still carries pressure switches, leave them alone. They do not affect how the new solenoids operate.
• Install a new pan filter and, on 2006 and earlier trucks, service the canister-style inline filter as well.
• Fill with the fluid specified for your VIN; the 5R110W was released on MERCON SP, which does not mix with MERCON or MERCON V.
• Clear codes and adaptive tables, then perform the engagement relearn with the fluid at 130 F.

If the clutches are burnt, solenoids will not cure the slip. The 5R110W overhaul kit for 2003-2004 is the matching rebuild kit for the early units, and our 5R110 rebuild wear points guide lists the hard parts Ford updated after the first years.

What part numbers does this kit replace?

The listing covers OEM Ford numbers 3C3Z-7G383AB, 3C3Z-7J136AA and 3C3Z-7J136AB. Check the numbers on your old solenoids against these before ordering.

Does it fit my 2005 F-250 with the 6.0L Power Stroke?

Yes, 2003-2006 F-250 and F-350 Super Duty trucks with the 6.0L and the 5R110W are listed for this kit. Send us your VIN if you want it checked first.

My 2003 has pressure switches on the solenoid body. Does that matter?

No. The computer on these trucks never monitored those switches and Ford removed them in late 2004. They have no effect on how the new solenoids work.

What else should I replace with the solenoids?

The pan filter and gasket every time, the inline filter on early trucks, and the internal harness if it is heat-cracked. If the fluid shows clutch material, plan on an overhaul instead.

Do I need a scan tool after installing it?

You need one to clear codes and adaptive tables. Then run the relearn: fluid at 130 F, five each of Park-Reverse, Drive-Reverse, Reverse-Drive and Neutral-Drive engagements, five seconds apart.
