Timely post. I am getting ready for the same project...
Go to a GM dealership and ask to read the service bulletin on this question of compatibility. Dexron VI reportedly works with older Dexron transmission fluids but you will want to confirm that with a dealer that does service on transmissions. It is also a best practice to remove as much of the old fluid as possible before refilling with the latest generation.All the transmission talk is confusing. We have HSW 630 V1’s and our recent oil analysis says it’s needs changing. 450 hrs (new boat to us). We’ve read the manual (Dex II) and looked through the updated bulletins (several), none of which are on the shelf. Is there a simple, mainstream solution to a recommended fluid? Help appreciated.
It’s ironic that I’ve been researching the same thing for weeks now.
I have downloaded the manual and read almost every post on this. It seems the list in the manual (and several posted here) has part numbers of fluids that I can’t find anywhere. I’m sure I’m overthinking it, but these transmissions would be expensive to change.
So a few hours ago I called ZF directly (North America office) and spoke to a guy in Miramar Florida. I gave him my model number and he gave me a fluid recommendation that was available in most auto parts stores currently. My transmission is different than yours (63 IV) so you might want to call them yourself to get the correct advice.
Also - he was nice enough to send me the owners manual. I did ask for the service manual after, but he said that was not available to me. Fortunaly I found more info online.
I found the contact number on the ZF website.
Hope that helps…
This is the manual. I also sent him this picture front and back of the container to verify it would meet the needs and he confirmed in an email “yes”.Hello Boatrboy
I also have a new to me 2004 sea ray 340 with the ZF631v 2.0 transmissions and would like to service them, could you relay the information that you received directly from ZF, and would you be able to share the owners manual.
Any help would be welcome
