Probably the wordiest title to a Blog article yet – my apologies. What I am talking about is the Thermostatic control valve mounted to the Touchtronic II 6-speed Automatic Transmission fitted to most Aston Martin DB9’s, DBS and Rapides from 2004 to 2014. This valve controls the flow of hot automatic transmission fluid to the oil cooler/radiator mounted at the front of the car, regulating its temperature. You may need to remove the valve to service it, the oil cooler lines, or to remove the transmission oil pan/sump (like I am doing in my series on changing the automatic transmission fluid and seals – read about that here). The oil cooler lines hold about 1.6 liters of transmission fluid so you might want to drain those. Let me show you how to remove the valve and drain the lines.

I wanted to change the Automatic Transmission fluid in my DB9 (check out my entire series on this in another article). Part of that process is to drain the fluid from the oil pan/sump. Keep in mind that just draining the fluid from the sump and then refilling what comes out is NOT all it takes to change all the fluid. In fact you’ll only be draining about 40% of the total amount of fluid in the transmission during this process. To get the other 60% you should really check out my entire series on this.

If you are trying to access some of the components on the right hand side of the 6-speed Touchtronic II automatic transmission fitted to most Aston Martin DB9s, DBS and Rapides between 2004 and 2014 you’ll find you have almost no access. The exhaust pipe is very close, and Aston fitted a heat shield to protect the transmission. But, that heat shield is even closer to the transmission. If you remove it you finally have enough room to get some skinny fingers into those tight places and can get some work done. For me, I was working on Changing the Transmission fluid (of which I’ve done a complete series of articles on that you can find here). Let me show you how to remove the heat shield.

I’ve just changed the Automatic Transmission Fluid on my DB9 after 15 years and 45K miles.  The process applies to other Aston’s like the DBS and Rapide fitted with the Touchtronic II 6-speed automatic transmission made by ZF.   I’ve prepared an entire series describing the whole process, and you can find the index article for that here. As part of that process I spend sometime determining which tools would be needed to get the work done, PLUS I discovered a few tools and supplies that will make the process much easier. I wanted to share that with you in this article.

If you own an Aston Martin DB9, DBS, or Rapide from 2004 to about 2014 and it has an Touchtronic II  6-Speed automatic transmission, the official Aston Martin Service guide says the transmission is ‘Filled for Life’.  In another article I debunked this idea (read the full article here), and uncovered the transmission manufacturer lists the service interval as a more realistic 80,000 to 120,000 kms (50,000 to 75,000 miles) or eight (8) years at the longest.    If you have an Aston Martin made before 2011 you are likely due for an automatic transmission fluid change.   If you are interested in doing it yourself (as I am) then you’ll need to know what very specific parts to track down.  This article will point you at what you need and give you some options on where to get them.

Hello readers. I’ve just released the epic 7 part video series (epic to me at least) on how to change the transmission fluid in a DB9 fitted with a 6-speed automatic Touchtronic II transmission. Most DB9, DBS and Rapide’s from 2004 to 2014 were fitted with this transmission.
