7. Connect all the internal wiring harness electrical connectors to the electrical components (1-6).
8. Install the 1-2 accumulator. Refer to Accumulator Assembly, Spacer Plate, and Gaskets (See: Automatic
Transmission/Transaxle/Accumulator/Service and Repair) .
9. Connect the transmission harness 20 way connector to the transmission pass-through connector.
Align the arrows on each half of the connector and insert straight down.
10. Install the transmission oil pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement (See: Automatic

11. Lower the vehicle.
12. Fill the transmission to the proper level with DEXRON(R) VI transmission fluid. Refer to Transmission Fluid Check (See: Automatic
Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/4L60-E/4L65-E/4L70-E - Automatic
Transmission/Transmission Fluid Check) .
Note
It is recommended that transmission adaptive pressure (TAP) information be reset.
Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, the engine control module (ECM), powertrain control
module (PCM) or transmission control module (TCM) will need to relearn TAP values. Transmission performance may be affected as new TAP values
are learned.
13. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) (See: Automatic Transmission/Transaxle/Description and
Operation/4L60-E/4L65-E/4L70-E - Automatic Transmission/Transmission Adaptive Functions (TCM)) .
