Yes, I assumed this thread is about a Aisin-Warner TF80SC automatic transmission. A modern manual trans with synthetic oil should have no problem with 100,000 mile service intervals. Of course,...

As a professional, I would recommend automatic transmisiion fluid replacement every 30 to 50k miles. I will never understand Volvo's stance on "lifetime auto trans fluid unless towing".

2012 XC 70 with Gen II TF80SC should take Volvo 31 256 774, which is not a 3309. More like a Toyota WS,AW-1 application.

As far as the info that I can find, Yes. Unless one used synthetic Dex VI with Lubegaurd Platinum or Lubeguard Black (HFM) to convert the Dex VI to a highly friction modified fluid. You also get a...

There is no need to use LB Platinum with Spirax, Spirax is an ALL APPLICATION JWS 3309 trans fluid, and personally I would pick it over both options. Check out the PDF link. I only use Platinum for...

Bill, thanks for asking. Let me first say that my reason for disliking Trans Tune is that it is solvent based(naphtha) and solvent is not something I would add to trans fluid. LubeGuard trans flush...

I am well aware, I just call it Sea Foam, again not something I would use or recommend.

edit - I just asked all my tech's, none of them would recommend it. I am glad it has worked for you, though.

Bill, I would never put a cleaner such as Sea Foam into a normal operating transmission. I rebuild transmission's of all variety and I put a bottle of Lubeguard into each and every one, so I do have...

Personally, I would not use Sea Foam. I am skeptical of most transmission fluid additives. The ONLY one I will(and do) use is LubeGuard products.
