TCM Learning

When shift shock occurs or parts related with the transmission are replaced, TCM learning should be performed.

In the following case, TCM learning is required.

• Transmission assembly replacement
• TCM replacement
• TCM upgrading

1. TCM learning condition
   1. ATF temperature: 30 ~ 95°C (86 ~ 203°F)
2. TCM learning procedure
   1. Stop learning
      • Repeat the shift pattern shown below four times or more with the brake stepped on.

   2. Driving learning
      1. Upshift the gear from 1st to 8th by one gear while keeping the throttle opening constant
      2. Gradually reduce the speed and downshift the gear from 8th to 1st by one gear.
      3. Repeat the driving pattern above four times or more.

         Upshift throttle opening: 15-30%
