4R70W Tcc Solenoid 1996-1997, remanufactured and ready to install. Fits the 4R70W. Ships fast from the USA.
Read this first: the part sold on this page is a complete remanufactured 4R70W valve body for 1996-1997, supplied with its solenoids, not a loose TCC solenoid. The rebuilder updates the converter clutch circuit inside it, which is why it shows up when people search for a 4R70W TCC solenoid. If your 1996 or 1997 F-150, Expedition, Crown Victoria, Grand Marquis, Town Car or Mustang has lockup shudder, a converter that will not lock, soft or sliding shifts, or solenoid codes that came back after a new solenoid pack, this is the bigger fix.
Everything the PCM asks for happens here. Two on/off shift solenoids pick the gear, the EPC solenoid sets line pressure, and the TCC solenoid signals the bypass clutch control valve to apply or release the converter clutch. A new solenoid only helps if the valves it feeds still seal in their bores. On high-mileage units the aluminum wears around the pressure regulator, boost and converter clutch valves, and that leakage produces the same complaints as a failed solenoid.
This unit was rebuilt with an updated pressure regulator valve, updated boost valve, updated TCC sleeve, updated converter pressure valve and updated solenoid regulator valve, then tested on a VBT-4000 valve body tester before it shipped.
Scan for codes first, but remember a solenoid code describes the circuit, not just the part. Check the case connector and harness, then compare live lockup command against engine and turbine speed on a road test. Our 4R70W shift solenoid testing guide lists the resistance checks by connector, and the EPC and line pressure guide explains how pressure regulator bore wear mimics a bad EPC solenoid. If the solenoids test good and the fluid is clean, the bores are the likely problem and a rebuilt body is the honest repair.
The 1996-1997 4R70W is its own valve body generation. Sonnax identifies it as the soft-wire harness version with 10mm dowel pins and an F6 rough forging; 1998-2000 bodies share the casting but switch to the molded lead-frame solenoids, so the solenoid style is how you tell them apart. The early units also use the 10-pin case connector. A 1998-or-later body will not plug into your harness. Look at your old solenoids before ordering, or send us your year and VIN and we will match it. Browse the full 4R70W parts collection for other years.
A valve body cannot fix a worn direct clutch or a failed converter. If the fluid is black or full of friction material, read the 4R70W Crown Victoria common problems guide before you commit, because those failures look similar from the driver's seat.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is a complete remanufactured 4R70W valve body for 1996-1997 supplied with solenoids. The converter clutch circuit is updated inside it, including a new TCC sleeve, so it addresses lockup problems that a single solenoid cannot.
No. 1998 and later units use molded lead-frame solenoids and a different case connector. This body is for the 1996-1997 soft-wire harness design. Send us your year and VIN if you are not sure.
Ford specifies MERCON V for the 4R70W. Do not add friction modifiers or additive treatments, and check the level at operating temperature.
Often, yes. Wear at the bypass clutch control valve and sleeve causes slipping lockup, no lockup and converter codes even with a good solenoid. Confirm the converter itself is not the problem first.
Clear the PCM adaptive memory, verify the fluid level hot and drive through several upshifts and lockup applies so the PCM can relearn.
