What is the one way clutch on a Ford AODE?
What is the one way clutch on a Ford AODE?
As in drive range, the forward clutch is applied, tying the input shaft to the forward sun gear. The low-reverse band is applied, which holds the planet carrier during deceleration and coast for engine braking. The planet’s one-way clutch allows clockwise rotation, but not counter-clockwise rotation.
What’s the difference between the AOD and the 4R70W?
The AODE/ 4R70W differs from the AOD in input. The AOD has dual input shafts (inner and outer); the AODE/4R70W has one, which splines into the forward clutch. Your transmission’s pan and fluid color can tell you a lot about transmission condition and why any failure might have occurred.
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.

What should I replace in my Ford AODE 4R70W?
Adjacent is the converter clutch solenoid, which receives a pulse input for smooth engagement. This TCI Automotive transmission overhaul kit has just about everything needed to complete an AODE/4R70W rebuild. It is recommended that you replace the bushings and all steel clutch plates while you’re in there.
What kind of shaft does the Ford AOD have?
The AOD has dual input shafts (inner and outer); the AODE/4R70W has one, which splines into the forward clutch. Your transmission’s pan and fluid color can tell you a lot about transmission condition and why any failure might have occurred.
When did Ford stop making the AOD transmission?
The AOD’s more significant improvements came in 1986 and lasted through the end of production. Ford developed the AODE and 4R70W to achieve cohesive engine and transmission function in 1991. This Tech Tip is From the Full Book, FORD AOD TRANSMISSIONS: REBUILDING AND MODIFYING THE AOD, AODE AND 4R70W.
