Test Procedure

Before road testing, note the following information:

• No overdrive upshift or TCC lock-up will occur when engine coolant is below 140°F (60°C) on Lexus models.
• No 3rd upshift or TCC lock-up will occur when engine coolant temperature is below 95°F (35°C) and speed is below 25 MPH on Lexus models.
• No overdrive upshift or TCC lock-up will occur when engine coolant temperature is below 133°F (55°C) on Land Cruiser or below 140°F (60°C) on Tacoma, Tundra and 4Runner models.
• No overdrive upshift or TCC lock-up will occur if a 6 MPH difference between set cruise control speed and actual speed exists on all models.
• All shift points vary due to transfer case gear position on Tacoma, Tundra and 4Runner models.
• Overdrive gear and TCC lock-up are cancelled when transfer case is engaged in L4 on Tacoma, Tundra and 4Runner models.
