The Toyota Yaris has been a common sight on Irish roads since its launch in 1999. It remains very popular today and because of the volume of Yaris vehicles in use it is one of the mainstays of many independent garage businesses.

A common maintenance issue with the Yaris concerns the Multi-Mode Transmission, an area where Asian parts specialist Blue Print can offer a very effective and economical solution.

The Multi-Mode Transmission or MMT is a type of sequential manual gearbox offered by Toyota on pre-2017 models. Instead of a conventional automatic transmission which uses hydraulics and a torque convertor, the MMT has a conventional friction clutch and mechanical gear selector mechanism which is controlled electronically.

Blue Print says before removing an MMT gearbox for a clutch replacement, it is important to first set the clutch actuator to the ‘clutch clamp’ position. Failure to carry out this operation is likely to cause the clutch actuator to be in the incorrect position on reassembly of the gearbox. This could result in a multitude of problems such as clutch slippage, harsh and delayed engagement, or no clutch operation at all.  A suitable diagnostic tool can facilitate this step, although it is possible to complete the procedure manually without a diagnostic tool by following Blue Print’s manual procedure, found on Blue Print Live.
