lockup-mate is a torque converter clutch (TCC) lockup kit for your automatic transmission

lockup-mate is our entry level automated lockup kit. Where auto-mate works best in either DRIVE or SPORT mode of the transmission, lockup-mate works best in SPORT mode

​Why should you install a TCC lock-up kit?​​

  • Significantly reduced transmission temperatures, especially when towing

  • Improved fuel efficiency​

  • Improved TCC operation if you have larger than standard tyres​

The benefits of locking your TCC are well known when experiencing heavy load conditions such as towing (caravan, boat or horse float), climbing long steep-hills, or when driving in softer sand.​

​Transmission torque converter slippage not only results in excessive heat buildup, but also uses more fuel.​

When enabled by the driver, lockup-mate AUTOMATICALLY: 

  • Activates the TCC lock-up when the conditions are right; but more importantly, then disables it under conditions that would put excessive stress on the transmission​

  • Then, re-locks it again when suitable 

  • In SPORT mode it enables lockup from 30kph+ (when the right gear is chosen) and 80kph+ when in DRIVE mode.

  • Automatically adjusts for low or high range 4WD

lockup-mate Features

  • Adjustable sensitivity.  Tune it to your vehicle's unique configuration or your driving preference.

  • Choice of gear when lock-up will start [2nd-5th].  Default is 2nd gear.

  • In SPORT mode, it will lockup whenever the conditions are suitable (from 2nd gear).  In DRIVE mode, it will lockup above 80kph when the conditions are suitable. 

  • Mimics the A/T ECU's complex PWM activation method (ie, not just simple on/off PWM control)  

  • Uses the OBD2 port, but still allows you to connect and use your favourite OBD2 device without interference (eg, a ScanGauge, ELM327 bluetooth adaptor with Torque App, UltraGauge, head up display, etc)

  • Reminds the driver to down-select a gear with a flashing LED, when the torque converter unlocks in SPORT mode

  • AND, it means you don't need be an expert anymore to use a torque converter lock-up!

Why is lockup-mate different to other lockup kits?​

  • It is the only TCC lock-up kit available that avoids 'the quirk' Learn more about the quirk

  • SafeLock® , which avoids locking the torque converter clutch under high slip conditions for maximum reliability

  • Forgetting to unlock the torque converter clutch can result in potentially damaging stresses in the drivetrain. lockup-mate avoids this by connecting to you car's OBD2 port to read important vehicle parameters (such as pedal position, speed, gear, 4WD mode, and RPM).  The micro-computer at the heart of lockup-mate uses an optimised algorithm to ensure the torque converter is only locked under the right conditions.

  • It works in harmony with the car's internal digital communications network (CANBus) to read more information to optimise its operation.

  • Safer, more reliable, more capable, and more accurate.

  • Simpler DIY installation.


No other lockup kit available works like lockup-mate and auto-mate!

​Take the worry away from using a torque converter lockup kit and return the protection normally provided by the transmission ECU, but with a better (and user adjustable) lockup algorithm!

​Best of all, lockup-mate is affordable and will soon pay for itself in fuel savings if you tow heavy loads. ​
