Toyota hilux 2011 model trouble code p2716 - Toyota Cars & Trucks

Here is some info. I hope it helps.

This is a code relative to shift solenoid malfunctions in your computer. This is a known problem on your model and Toyota released an updated PCM to correct the problem.
While you can replace the PCM yourself if you are out of warranty, your dealer will need to code your VIN to it in order to get rid of the check engine light.
The warranty coverage is 8 years or 80,000 miles from new.

The details of the bulletin are below:
