2. Inspect and Replace Transmission Fluid

Step 1: Locate the transmission dipstick and remove it to check fluid level. If low, add the appropriate transmission fluid.
Step 2: If fluid is burnt or contaminated, drain the transmission fluid using a drain pan. Remove the transmission pan if applicable.
Step 3: Replace the transmission filter if necessary. Clean the pan and replace the gasket.
Step 4: Refill the transmission with new fluid, according to the manufacturer's specifications.

3. Inspect and Replace Transmission Mounts

Step 1: Lift the vehicle and securely support it on jack stands.
Step 2: Locate the transmission mounts and visually inspect for cracks or deterioration.
Step 3: Remove the bolts securing the mounts and replace with new mounts if damaged.
Step 4: Reinstall bolts, ensuring they are torqued to manufacturer specifications.

4. Check and Replace Transmission Solenoids

Step 1: Disconnect the battery to avoid electrical shorts.
Step 2: Access the transmission solenoids, typically located on the valve body.
Step 3: Remove any connectors and bolts holding the solenoids in place.
Step 4: Replace solenoids with new components, ensuring proper alignment and connection.
