Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Transmission fluid pump
- Drain pan
Ensure the vehicle is on a level surface and securely raised on jack stands.

2. Fluid Change

Sub-steps:
1. Drain Transmission Fluid:
  - Place a drain pan under the transmission pan.
  - Remove the transmission pan bolts using a socket set.
  - Carefully lower the pan to drain the fluid completely.
2. Replace Transmission Filter:
  - Remove the old transmission filter and discard it.
  - Install the new filter, ensuring it is seated correctly.
3. Clean the Pan:
  - Clean the transmission pan thoroughly, removing any old gasket material.
4. Reinstall Pan:
  - Apply a new gasket or sealant to the pan.
  - Reattach the transmission pan using the torque wrench to tighten the bolts to the manufacturer's specifications (typically around 8-10 ft-lbs).

3. Refill Transmission Fluid

Sub-steps:
1. Add New Fluid:
  - Use the transmission fluid pump to refill the transmission with the correct type and amount of fluid (Toyota Type T-IV).
  - Check the owner's manual for the exact fluid capacity.
2. Check Fluid Level:
  - Start the engine and let it idle in park.
  - With the engine running, check the fluid level using the dipstick; add fluid as necessary.

4. Test Drive

Sub-steps:
1. Take the Vehicle for a Test Drive:
  - Drive the vehicle under various conditions (stop-and-go, highway speeds) to check if the slipping issue persists.
2. Monitor Performance:
  - Pay attention to any unusual noises or behavior during acceleration.
