AUTOMATIC TRANSMISSION HARSH SHIFT - SOLENOID REPLACEMENT

SERVICE PROCEDURE:
1.

Attach a GDS and select DTC Analysis and A/T menu. Record the DTC and description.
Delete the DTC.
• If DTC are found, repair according to TSB or shop manual information.
• If no DTC are found, go to Step 2.

2.

From the GDS home screen, select Data Analysis and A/T menu and the solenoid parameters
shown below. If the solenoids show:
• Continuous and changing output while driving, the wiring currently has no open/short
circuits. Go to Step 4.
• No continuous and changing output, go to Step 3.

3.

Visually check the wiring harness between the TCU and transmission for a damaged wire or
connector. Check for an open/short circuit.
• If so, repair or replace the ECU control harness and drive the vehicle to confirm the repair.
• If no damage is found, go to Step 4.

4.

Record the audio preset stations and disconnect the negative battery terminal.

Locate the harness connector on the passenger
side of the transmission.
Press the tab in the center of the latch and push
the latch upward.
Push the connector up to disconnect the
connector from the valve body.
To gain better access to the connector, place a

drain plug and drain the ATF. Reinstall the drain
plug.
NOTE: If the ATF has metal particles or has a
burnt smell, open a prior authorization to replace
the transmission.
Torque: 22~24 lb.ft (3.0~3.3 kgf.m, 30~32 N.m)
