Hello,

This light means the transmission has had a problem with one of the sensors. In most cases it will be an input or output shaft speed sensor. The best thing to do is scan for trouble codes so we can be sure which sensor to replace.

If it is a shaft sensor this video will give you an idea of what you are in for when doing the job.

Please let us know what happens.

Cheers, Ken
