I’ve been curious to learn more about the Automatic Transmission fitted to the DB9’s.   I’m talking about the 6-speed Touchtronic II paddle shift unit that was in the majority of DB9’s from 2004 until 2014 when they changed to the Touchtronic III 8 -speed.  The DB9 had an option for a 6-speed manual transmission (stick shift) but those are rarer and I don’t have one.

What got me wondering were a few common sense questions:

• How do you tell if the transmission fluid is topped up?
• When does the transmission fluid need to be changed?
• Is there a transmission fluid filter that needs to be changed?

Surprisingly, there were no simple answers.  Here’s what I learned.
