my Honda CR-V transmission hesitates when shifting what could be the issue

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, fluid catch pan, funnel, rags, multimeter
• Ensure vehicle is on a level surface and the engine is turned off.

2. Transmission Fluid Change

1. Drain the Old Fluid:

   • Place a fluid catch pan under the transmission pan.
   • Remove the drain plug or the transmission pan bolts to allow fluid to drain completely.
   • Dispose of old fluid according to local regulations.

2. Replace Transmission Filter (if applicable):

   • Remove the transmission pan completely.
   • Take out the old filter and replace it with a new one (ensure it fits the specific model).
   • Clean the pan and the magnet inside to remove any debris.

3. Reinstall Transmission Pan:

   • Apply a new gasket or sealant to the pan if needed.
   • Torque the pan bolts to the manufacturer's specifications (typically around 10-15 ft-lbs).

4. Refill with New Fluid:

   • Using a funnel, refill the transmission with the recommended type of fluid (consult owner’s manual for specifications).
   • Check fluid level using the dipstick as per manufacturer's guidelines.

3. Inspect and Repair Control Module

1. Inspect Wiring and Connectors:

   • Check the wiring harness to the TCM for loose or damaged wires.
   • Clean and reconnect any corroded connectors.

2. Test the TCM:

   • Use a multimeter to test for proper voltage and resistance according to the service manual.
   • Replace the TCM if it fails the test.

4. Throttle Position Sensor Check

1. Inspect TPS:

   • Locate the TPS and ensure it is securely connected.
   • Use a multimeter to check for proper voltage output while moving the throttle.

2. Replace if Necessary:

   • Disconnect the TPS connector.
   • Remove the screws holding the TPS and install a new unit.
