Solution

1. Preparation

Ensure the vehicle is on a level surface and engage the parking brake.
Gather all necessary tools and parts required for the repair.

2. Transmission Fluid Change

Drain Old Fluid
- Locate the transmission drain plug and use a socket wrench to remove it.
- Allow the old fluid to completely drain into a suitable container.
Replace Transmission Filter
- Remove the transmission pan by unbolting it with a socket set.
- Carefully detach the old filter and install the new filter, ensuring it is properly seated.
Clean Transmission Pan
- Clean the transmission pan with a suitable solvent and a lint-free cloth.
- Replace the gasket or apply new RTV sealant if necessary.
Refill Transmission Fluid
- Reattach the transmission pan and tighten the bolts to the manufacturer’s specified torque.
- Using a funnel, fill the transmission with new, manufacturer-recommended fluid through the dipstick tube.
- Start the engine and cycle through the gears while checking the fluid level, adding more if necessary.

3. Inspect and Repair Drivetrain Components

Check CV Joints and Driveshaft
- Inspect the CV joints for any signs of wear or damage and replace if necessary.
- Examine the driveshaft for any play or damage and replace if required.
Test Drive
- After repairs, take the vehicle for a test drive to ensure smooth operation and that the slipping sensation has been resolved.
