Thanks for the reply. I picked up 2 gallons of Valvoline Dex VI. Checked a couple of sites for compatibility and it looks OK to use. I'll put 6 or 7 quarts in and check the level and continue filling from there. When I check the 09 hybrid trans fluid specs, I've seen 7 quarts as the capacity. But I'll go slow and not overfill it. Then I'll drain the engine oil, replace the filter and start over. Pretty expensive oil change! Oh well, that's just how things go somedays. Thanks again for your reply.
You bought 8 quarts, and I think you are going to need 15-17 quarts. You should be able to buy what you need from your local parts store. Most use the Dex6 Valvoline Max-Life, as it meats all the specs, and is cheaper than the OEM fluid.
Before you start, since you already drained it... Its a good time to replace that tranny filter.. But I am hesitant to say that since I know on the 6L versions, the Y-Pipe gets in the way. I cant remember for sure on the 2L if thats the same story.
Little bit more info than you asked for... But..
Although I own a Rivian, I still have a soft spot for these Hybrid GMT's. I would like to find a low mileage 2012-2013.. But the 1.5 gens usually sell for stupid money. The 1st gens (2008-2010.5) were the years that had more problems thru of the Shared Technology program. The Hybrid system in the GMT was borrowed from Toyota, and then used by and GM and Chrysler/Cerberus Capital. For some reason, once Chrysler/Cerberus dropped out of the Hybrid in 2009 model year, for GM the 2010.5 and up became a very good vehicle, but the damage to the name was already done at that point.
