Solution

1. Preparation

Gather all necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Using a dipstick, remove the transmission fluid dipstick and wipe it clean.
Reinsert the dipstick, remove it again, and check the fluid level; add fluid if low using Honda ATF DW-1.
If the fluid is discolored or has a burnt smell, proceed to replace the fluid.

3. Replace Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts and carefully lower the pan to drain the old fluid.
Replace the transmission filter if applicable.
Clean the pan and install a new gasket.
Reattach the pan and torque the bolts to manufacturer specifications (typically 7-9 lb-ft).
Refill with new Honda ATF DW-1 fluid through the dipstick tube.

4. Inspect and Adjust Shift Linkage

Locate the shift linkage under the vehicle.
Check for any loose or damaged components; tighten or replace as necessary.
Adjust the linkage according to the service manual specifications to ensure proper alignment.

5. Test and Replace Solenoids (if necessary)

If solenoids are found to be malfunctioning during the diagnostic step, disconnect the transmission harness.
Remove the faulty solenoid(s) and replace with new ones.
Reconnect the harness and ensure all electrical connections are secure.
