I find myself the caretaker of a 2012 Impala; 3.6L DOHC and 6T75E (?) or 6T80E (?) transmission. It's a 6-speed auto at any rate. Car is generally in wonderful condition, but trans fluid is more brown than I'd really prefer. I bought a 5-gallon pail of Dex-VI and a trans filter from O'Reillys. I was getting-up the gumption to drop the pan, replace the filter, remove a cooler tube, and flush the fluid. I'm reading on another forum that the trans filter is "lifetime", the trans has to be dropped-out and split-open to access the filter. Is this true? Seems unlikely given that O'Reillys had the filter in stock, and it looks like any other modern, black-plastic trans filter. I normally buy a service manual set for any vehicle I own...but there's no used manuals on eBay; and new ones from Helm are $300. And--technically--I don't actually own this car. For the record--and I hate admitting this--this Impala will absolutely EAT my '92 or '93 Lumina Euro 3.4L DOHC vehicles. I used to think of the W-body Impalas as "W Impalas" --> "WIMPalas" but I'm done with that now. Holy crap, this 3.6L moves compared to the 3.4L.

So, no one has a clue what this is? One good thing that I’ve learned is that Rock Auto carries a headliner (see, I found out what the piece that covered the ribs is called, LOL) for these cars, will be ordering one.

^ Yeah, Matt used to take the *cut & weld* approach, I couldn't understand why he did them that way seeing as he is/was a machinist at the Toyota plant in Woodstock here in Ontario & had access to the needed tools. I prefer to cut the ends & rethread them.
