Lock-Up Control Solenoid Valve/Shift Control Solenoid Valve "A" Assembly

WARNING: This page is about a different car, the 1998 Honda Odyssey, 1998 Honda Accord, and 1998 Acura 2.3CL. However, it is still accessible from the selected car via links, so may be relevant.
  1. Lock-up control solenoid valve/shift control solenoid valve "A" assembly is located on transaxle. Disconnect harness connector at valve assembly. See Figure .
  2. Using a DVOM, measure resistance between ground and terminal No. 1 (lock-up control solenoid valve), then between ground and terminal No. 3 (shift control solenoid valve "A"). See Fig 1 .
  3. Resistance should be 12-25 ohms. Replace lock-up control solenoid valve/shift control solenoid valve "A" assembly if resistance of either solenoid valve is not within specification.
  4. Check lock-up control solenoid valve/shift control solenoid valve "A" operation. Ensure solenoid valve body is grounded. Apply battery voltage to terminal No. 1 or terminal No. 3. A clicking sound should be heard, indicating solenoid valve operation. Replace lock-up control solenoid valve/shift control solenoid valve "A" assembly if either solenoid valve fails to operate.
