See Figure 10 for a partial hydraulic-circuit diagram identifying the 2001-and-up hydraulic circuit. Case –Īs shown in Figure 9, the overdrive-servo bleed orifice was eliminated to accommodate the hydraulic-circuit changes in the overdrive-servo regulator valve. The main valve body had casting changes to accommodate the elimination of the orifice-control valve and the 2-3 capacity modulator valve (see figures 7 and 8). The retainer for the accumulator spring had a dimensional change to accommodate the elimination of the plate over the direct-clutch accumulator. electronically controlled, the valve body still controls full-throttle shift firmness and the ultimate torque-capacity of the transmission. The 4R70W has been used for many years in Ford, Lincoln & Mercury products.

Ford went to electronic control not only for engine/transmission cohesion, but also improved shift quality by removing the short-comings of mechanical control. Refer to Figure 5 for a view of the previous-design spacer plate. The AODE/4R70W is a 4-speed, rear-drive automatic overdrive with electronic control, hence the AODE designation. The bolt holes were eliminated from the spacer plate, along with the plate over the direct-clutch accumulator. Figure 4 shows that a change also was made to the cover plate connecting the forward-clutch circuit to the 3-4 capacity modulator valve. JEmail Share Tweet Ford AODE, 4R70W, 4R75W, 4R70E, 4R75E Valve Body Layout Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. The spacer plate in the 2001-up design had hole changes to connect the added over-drive-servo regulator-valve boost valve and sleeve to the EPC-solenoid circuit, and to accommodate the changes in the 3-4 capacity modulator valve. The most-obvious change is the elimination of the plate over the direct-clutch accumulator (see Figure 3). Transmission Diagrams Optional Features Manual Shift Connections Shiftware Important Information Troubleshooting Contact READ BEFORE PROCEEDING Before installing the Quick 1 unit, we recommend you read the manual from beginning to end. The upper and lower spacer-plate gaskets in the 2001-up design had numerous hole-configuration changes to accommodate the hydraulic changes with the valve body. The lower side of the valve body had casting changes to connect the 2-3 back-out valve to the shift solenoid 2 hydraulic circuit, as shown in Figure 1.įigure 2 shows the previous-design casting and identifies the EPC circuit that was connected to the 2-3 back-out valve on the earlier models. Note: This change also carries over to the 4R70E and 4R75E models.įor improved durability.
