- Install the EPC solenoid bracket and bolt. See Figure. Inspect the lead frame for damage. Using the Transmission Solenoid Connector Gauge (307-426), check all lead frame solenoid connections. See Figure.
- The gauge should fit tightly and not fall out after being inserted. If the transmission solenoid connector gauge passes through any lead frame connector pins or does not feel like it makes a good contact, install a new lead frame.
- Connect the molded lead frame to the solenoids. See Figure. Connect the bulkhead inter-connector by pressing it in place by hand and fully seating the connector in place.
- Connect the EPC, TCC and shift solenoids "A" and "B" by pressing them in place by hand and fully seating the connector in place. Ensure that the terminals pass fully through the connector slots.
- Install the manual control lever. See MANUAL LEVER SHAFT & SEAL .
- Install the transmission fluid pan and filter. See DRAINING & REFILLING under LUBRICATION.
- Lower vehicle. Fill the transmission with appropriate fluid to proper level and check for correct transmission operation. See LUBRICATION .
