Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid pump, funnel, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick (if equipped) or the transmission fluid fill plug.
Remove the dipstick or fill plug and check the fluid level and condition.
- If low, add the recommended transmission fluid type (typically Toyota ATF WS).
- If dirty or burnt, proceed to change the fluid.
Using a transmission fluid pump, drain the old fluid from the transmission pan.
Replace the transmission fluid with new fluid until it reaches the proper level.
Reconnect the dipstick or fill plug securely.

3. Inspect Transmission Control Module (TCM)

Locate the TCM, typically found near the transmission or under the dashboard.
Disconnect the wiring harness from the TCM and inspect for corrosion or damage.
If necessary, clean the connectors with electrical contact cleaner.
Reconnect the wiring harness securely.

4. Reset Transmission Adaptive Learning

Reconnect the negative battery terminal.
Start the vehicle and allow it to idle for a few minutes.
Drive the vehicle through various speeds and conditions to allow the TCM to relearn shift points.
