how to fix Honda Accord transmission slipping when accelerating

Solution

1. Preparation

• Gather tools and parts needed 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 and Replace Transmission Fluid

1. Inspect Fluid Level:

   • Remove the transmission dipstick; check fluid level and condition.
   • If low, add the recommended type of transmission fluid (consult the owner's manual).

2. Drain Old Fluid:

   • Place a drain pan under the transmission pan.
   • Remove the transmission drain plug or pan bolts to allow the fluid to drain completely.

3. Replace Fluid Filter:

   • Remove the transmission pan completely if not already done.
   • Take out the old filter and replace it with a new one.

4. Reinstall Transmission Pan:

   • Clean the mating surfaces of the pan and transmission.
   • Install a new gasket and torque the pan bolts to the manufacturer's specifications (typically 10-12 ft-lbs).

5. Refill Transmission Fluid:

   • Reinsert the dipstick and add new transmission fluid through the dipstick tube.
   • Start the engine and let it warm up, then shift through all gears while checking for leaks.

3. Inspect and Repair Transmission Components

1. Check for External Leaks:

   • Inspect all seals and gaskets for leaks; replace any that are worn.

2. Test Solenoids and Sensors:

   • Use a multimeter to test the resistance of the transmission solenoids and sensors.
   • Replace any faulty components as needed.

3. Adjust or Replace Transmission Bands (if applicable):

   • If equipped, adjust the transmission bands as per the service manual specifications.
   • If worn, replace the bands for better engagement.
