How to Change Automatic Transmission Fluid 6T45 2012 Holden Cruze Turbo Diesel

To accurately check your transmission fluid temperature check this video:

1. Buy yourself an ELM327 OBDII OBD2 WiFi Car Engine Diagnostic Code Reader from ebay.

2. Download the Torque Pro app from the Google Play Store - you will need the paid version - the "Lite" (free) version won't have the functionality you need.

3. Go into settings and choose "manage extra PIDs/Sensors". Then from the three dot menu on the top right of the screen, select "add predefined set". From the list, choose "Pontiac/GM/Opel/Vauxhall". That added 3 custom PIDs named "Transmission Fluid Temp (GM Method 1)" and "Transmission Fluid Temp (GM Method 2)" and "Transmission Fluid Temp (GM Method 3)". GM Method 2 picks up the right value I believe.

4. On the screen to "add sensor" choose "Transmission Fluid Temp (GM Method 2)" and add it to your screen.

This is the link to the check transmission level information I discuss in the video:

Total transmission fluid capacity is apparently 8.1 litres and not 6.

Even after doing a single fluid change there was a noticeable improvement in shift quality - nice and smooth.
