Solution

1. Preparation

Gather tools and materials:
- OBD-II scanner, socket set, torque wrench, pressure gauge, and a fluid catch pan.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Fluid Level Check:
1. Locate the transmission dipstick and remove it.
2. Wipe it clean and reinsert; check the fluid level against the markings.
Fluid Replacement:
1. If low or burnt, drain the old fluid by removing the transmission pan.
2. Replace the filter if applicable.
3. Reinstall the pan with new gasket, torquing bolts to manufacturer specifications (usually around 8-10 ft-lbs).
4. Fill the transmission with new fluid (Toyota WS fluid) through the dipstick tube until the correct level is reached.

3. Inspect and Adjust Shift Linkage

1. Locate the shift linkage and inspect for any wear or damage.
1. Adjust the linkage according to the manufacturer's specifications to ensure proper engagement.
1. Test the feel of the shifter after adjustment.

4. Repair or Replace Transmission Components

1. If slipping persists, consider removing the transmission for a detailed inspection.
1. Replace worn components such as clutches or bands.
1. Reassemble the transmission and reattach it to the vehicle, ensuring all connections are secure.
