Our transmission lock-up kits are the ideal performance upgrade for any Toyota owner looking for increase torque outputs and better reliability from their engines. But fitting your Toyota with an ECU transmission lock-up kit from Just Autos offers far more than just that…

Reduces Transmission Temperatures

When your engine is under duress, jumping between converter lockup and unlock can create excessive heat in your engine. Our lock-up kits will help your engine perform better and at cooler temperatures, even at higher RPMs.

More Torque to All Wheels

You can enjoy more torque delivery at the wheels and enhanced driving responsiveness from your Toyota. Having a more direct drive from the transmission increases power outputs and reduces the load on your brakes.

Enhanced Off-Road Driving

Activates the lockup when the conditions are right & disables it under conditions that would put excessive stress on the transmission or when extra torque is necessary to accelerate at low RPM - which is ideal for off road, technical rock driving.

Increased Responsiveness

Having an improved drive from the transmission makes for a more responsive vehicle.

Safer for You & Your Engine

Our lockup kits keep your engine running cool and adjusts for different driving environments.

Ideal for 4WD & 4x4 Enthusiasts

Tow and tour like never before with our ECU transmission lockup kit.
