I'm interested on doing this on my recently purchased used 2006 Honda Civic Hybrid, which has likely not had the fluid replaced at all for almost 140,000kms. This page mentions about how to check and top up the level but not fully drain it - where are the instructions / photos / diagrams on exactly where everything is that I have to unscrew to drain the fluid completely? Or is it super obvious?

 

The drain plug is super obvious, but you can't fully drain it. You can drain what's in the pan, but it's only a little over half the CVT fluid. Three 3 qt changes a week apart gets about 90% of the old fluid out.

Continue changing fluid every other oil change.

 

 

You can do it. Just don't over-tighten the plug and strip it out.

What you describe also sounds like engine mounts. At your mileage, both are likely issues.

If the vibrations at idle are worse at lower rpm like when you're using A/C, there's a very good chance you need to replace both upper mounts. That job has been described here, and it's far more challenging.

 

 

You were right! Had the transmission fluid changed at an independent honda mechanic and he showed me the transmission mount on the drivers side was cracked, so that explains the vibration I've been noticing. He advised me to order the mount and he will replace it for $120, which isn't too bad, so I'm working on sourcing that part affordably now.

Good news is the car is shifting better and driving much smoother after replacing the transmission fluid - the old fluid was quite dirty but not black, so I think I'm ok without triple-flushing it. I will be sticking to your advised every-other-oil-change schedule.

 

I got lucky with one off eBay. They are NOT the same as the regular civic. I got another off rock auto.

Be advised that you likely need to replace BOTH upper mounts.

 

Yep, I asked him about the other mount since you mentioned both on here and he took a good look at it and said it was fine, which surprised me as well. He seemed very knowledgeable and was familiar with this issue, and said it was very common, so I assume he was right that it didn't need replacing.

Thanks for the pointers on where to get a replacement part as well, will see what I can find. I have the official part number 50850-SNC-A91 which as you mention is specific to this hybrid model.
