Where is the EPC solenoid?
(EPC) Electronic Pressure Control The EPC controls a pressure regulating spool valve and spring that holds or releases fluid pressure, typically back to the transmission’s sump. It’s a variable force solenoid that changes at around 32 Hz (32 times per second).
How do you test an EPC solenoid?
TESTING ON/OFF SOLENOIDS The testing of on/off solenoids is straightforward. Pressure should be applied to the inlet, and if it is normally closed, you should not see pressure at the outlet. Once energized, you should see pressure at the outlet. For a normally open solenoid, the opposite is true.
How many electromagnetic solenoids does the 4R70W transmission use?
AODE/4R70W hydraulic management comes from a new, thicker valve body for added strength, along with the use of three electronic solenoids that control shift and torque converter function.
How many gears does a 4R70W have?
4 gears
4R70W indicates 4 gears, Rear wheel drive and Wider gear ratio compared to the AODE. The gear ratios are: First: 2.84 :1. Second: 1.55 :1.
What are the solenoids for Ford AODE / 4R70W?
When you build, use new Torringtons if possible. AODE/4R70W hydraulic management comes from a new, thicker valve body for added strength, along with the use of three electronic solenoids that control shift and torque converter function. Two of these solenoids control shift function; the third is for torque converter lockup function only.
What kind of sensor does a Ford 4R70W have?
To better tie the engine, vehicle, and transmission functions together, Ford went to an output shaft speed sensor and manual shift lever sensor, along with a multiplex electrical connector to simplify service. As the 4R70W evolved to the 4R75W, an input shaft sensor was added.
What kind of transmission does a Ford 4R70W have?
Although these transmissions have a great deal in common, they are also very different, with limits in interchangeability. The only inter-changeable components are geartrain related. The AODE/4R70W is a 4-speed, rear-drive automatic overdrive with electronic control, hence the AODE designation.
What is the solenoid on the converter clutch?
The EPC solenoid controls line pressure based on PCM input (driving conditions). Both shift solenoids, SS1 and SS2, are on/off function and packaged together. Adjacent is the converter clutch solenoid, which receives a pulse input for smooth engagement.
