Land Cruiser 200 Series (2007–2021) Torque Converter Lockup Kit

This upgrade is designed to provide a more direct connection between the engine and the transmission. By engaging the torque converter lockup, we eliminate the constant cycling between locked and unlocked states that causes instability in the transmission. To preserve the factory driving feel, the lockup function is automatically enabled only at speeds above 80 km/h. At lower speeds, particularly below 70 km/h, locking the converter can cause the engine to labor in higher gears due to reduced slip—so we avoid it by default. However, a secondary low-speed automatic mode is included, which allows lockup at lower speeds. When combined with the transmission’s active select mode, this feature lets you hold lower gears for improved engine braking when descending hills.

Each kit comes with a speed-sensing controller that manages the torque converter lockup engagement. This controller operates on two separate channels, allowing for dual-speed automatic lockup functionality.

The default lockup settings are pre-configured for plug-and-play use:

• Low-Speed Lockup: Engages at approximately 35 km/h
• Low-Speed Unlock: Disengages at approximately 30 km/h
• High-Speed Auto Lock: Activates at around 80 km/h
• High-Speed Auto Unlock: Deactivates at around 75 km/h

Key Benefits of the Lockup Kit:

• Lowers transmission temperatures by up to 50°C
• Prevents gear hunting and converter slip
• Enhances fuel economy while towing heavy loads, such as a 3-ton caravan
• Enables full engine braking in 2nd gear and above
• Fully automatic operation
• Uses a 12V signal to engage the torque converter solenoid, ensuring a firm lockup without clutch slip

By using this controlled locking method, the kit minimizes internal friction and wear, ultimately extending the life of your transmission. Our Lockup Kits have proven reliable, with no known failures attributed to their use in the Land Cruiser 200 Series.
