AODE Tcc Solenoid, new and ready to install. Fits the AODE. Ships fast from the USA.
An AODE-equipped Ford that shudders like it is crossing a cattle guard at 45 mph, or one whose tach never drops when it should lock up on the highway, often needs exactly this part: a single new torque converter clutch (TCC) solenoid from Rostra. It is the compact solenoid in the photo with the black can, the two-pin connector marked with blue stripes, an O-ringed nose and a mounting tab for its hold-down bolt. Owners of Crown Victoria, Grand Marquis, Town Car, Mustang and F-150 models built with this Ford four-speed family are the usual buyers, and at this price it is the cheapest first step on a lockup complaint.
The electronic AODE and the 4R70W that grew out of it lock the torque converter at cruise to stop slip and cut heat. The PCM decides when and grounds the TCC solenoid; the solenoid then sends signal oil to the bypass clutch control valve in the valve body, which strokes and routes pressure to apply the converter clutch. A solenoid that sticks, opens up electrically or leaks past its O-rings cannot hold that valve in the apply position, so the clutch drags instead of locking. The result is the vibration and higher cruise RPM drivers notice first, and enough extra heat over time to cook the fluid.
Check fluid level and smell first; varnished, burnt fluid causes shudder on its own and needs changing either way. Then measure the TCC circuit at the case connector. The Sonnax test booklet for this family gives about 10-16 ohms, so an open reading or a dead short sends you to the solenoid or the wiring. ATRA reminds techs that a circuit code covers the wiring, connector and computer, not just the solenoid, so wiggle-test the harness before replacing parts. Our AODE/4R70W solenoid testing guide shows the connector pinout, and the Crown Victoria common problems guide covers lockup complaints on the Panther cars that used this transmission. If the solenoid tests good and lockup still slips, Sonnax identifies wear at the bypass clutch control valve and sleeve as a common cause, which a solenoid cannot fix.
The listing names the AODE without a year range. Over its life this family used three solenoid connection styles, which Sonnax groups as 1997 and earlier, 1998-2008 and 2009-later, and the TCC solenoid did not stay the same across all of them. The surest check is to set your old solenoid beside the photo: the body shape, the two-pin connector and the position of the mounting tab should all match. If your transmission is a 1998-2008 unit, we also list a 1998-2008 AODE TCC solenoid sold by that year range. When in doubt, send us your year, model and VIN and we will confirm before it ships. Every other part for the family is on the AODE and 4R70W parts page.
If the pan is badly bent or keeps leaking, the 4R70W aluminum pan kit with filter handles the pan, filter and drain in one piece.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is one new TCC lockup solenoid made by Rostra, as shown in the photo. Filter, gasket and fluid are not included.
The listing names the AODE without a year range. Match the shape, two-pin connector and mounting tab of your old solenoid to the photo, or send us your year and VIN. We also list a separate 1998-2008 AODE TCC solenoid.
About 10-16 ohms across the TCC circuit at the case connector, per the Sonnax test booklet for this family. Open or near zero readings point to the solenoid or wiring.
If the solenoid has failed or its O-rings leak, yes. If the fluid is burnt, the bypass clutch control valve bore is worn or the converter clutch lining is glazed, the shudder can remain. Test before buying.
Mercon V. Ford's fluid chart lists Mercon V for the AODE-based 4R70W family and advises against additives.
