Take a Moment to Analyze What’s Going on

The service adviser transcribed the customer’s complaint as “stuck in manual mode,” and it was coming from a shop that didn’t want to work on it. After chiseling the Midwest winter ice off the vehicle I was able to go through my initial checkout. I found code P0705 stored in the PCM (Transmission Position Sensor (P R N D L) Malfunction).

A Very Big Clutch Job for a Very Small Car

Give ’Em an Upgrade
