All AOD-E transmissions and pre-1996 4R70W transmissions use a low-impedance torque converter clutch (TCC) solenoid that isn't compatible with our controllers. The correct solenoid should have a resistance of more than 7 Ohms. If you are not sure whether you need the updated solenoid, feel free to call our technical support line at (864) 646-8920 for assistance. If you need the correct TCC solenoid, it can be purchased locally. A typical application of the correct solenoid is for a 1996-1997 Mustang with a 4R70W transmission. Alternately, you can add the correct solenoid to your order below.

Despite looking the same, there are two versions of the later speed sensor. The first was used in 2001 - 2003 transmissions and has a 1 inch long barrel. The 2004 and up speed sensor has a barrel that is 5/64 of an inch shorter for a total of 15/16 inches long. The two sensors are not interchangeable. To make sure you are choosing correctly, measure the barrel of your sensor to see which one you have.
