why does my Honda CR-V Fifth Generation (2017-2022) transmission jerk when shifting

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid, rags, and a funnel.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery to prevent electrical issues.

2. Transmission Fluid Change

• Step 1: Remove the transmission drain plug using a socket wrench and drain the old fluid into a container.
• Step 2: Inspect the drain pan for metal shavings or debris; clean if necessary.
• Step 3: Replace the drain plug and torque it to the manufacturer’s specifications (typically around 30 lb-ft).
• Step 4: Remove the transmission fluid dipstick and use a funnel to add new transmission fluid, ensuring the correct type is used (Honda ATF DW-1).
• Step 5: Start the engine and let it idle for a few minutes, shifting through all gears to circulate the new fluid.
• Step 6: Recheck the fluid level with the dipstick and add more fluid if necessary.

3. Inspect and Replace Transmission Mounts (if damaged)

• Step 1: Raise the vehicle using a jack and secure it with jack stands.
• Step 2: Locate the transmission mounts and visually inspect for cracks or wear.
• Step 3: If damaged, remove the bolts securing the mounts using a socket set.
• Step 4: Replace with new mounts and torque bolts to manufacturer specifications.

4. Reprogram or Replace the Transmission Control Module (if necessary)

• Step 1: Connect the OBD-II scanner and check for any TCM-related codes.
• Step 2: If required, follow the manufacturer's procedure to reprogram the TCM.
• Step 3: If replacing, disconnect battery, remove the old TCM, and install the new one, reconnecting all harnesses securely.
