Mobil 1 55221 3309 Automatic Transmission Fluid - 1 Quart (Pack of 12)

As a dedicated DIY mechanic, I trust Mobil 1 synthetic products implicitly, and their 3309 ATF is no exception. This 12-quart pack is the only way to buy this fluid if you handle your own maintenance, offering both the highest quality protection and fantastic cost savings over purchasing single quarts at the auto parts store. The synthetic formula is where this fluid truly shines. After switching to Mobil 1, the transmission in my vehicle shifted noticeably smoother and quieter, especially during cold starts. It provides superior thermal stability, which is essential for protecting the transmission during heavy towing, hot climates, or stop-and-go traffic. It gives me peace of mind knowing the fluid is protecting critical internal components under the harshest conditions. The convenience of the 12-quart case is perfect. Whether you're doing a full fluid exchange or just a pan drop and refill, having the necessary volume on hand prevents frustrating last-minute runs to the store. This specific formula meets key manufacturer specifications and is a direct substitute for much more expensive dealer-branded fluids. If your vehicle calls for a high-quality 3309-spec fluid, this is the best protection you can buy in the most convenient package.

You can never go wrong with Mobil 1

Great product, fast shipping and works well. Very well priced considering other fluids on the market. Worked great for my 955 cayenne

Have been running this in AISIN AS69RC for a few years now with no issue. Fluid looks fine on factory flushes, trans doesn't overheat, shifts perfect (well, after being flashed with an update at the dealer, but that had nothing to do with fluid). Don't wait your money on the stuff from MOPAR/FCA, it's a marketing gimmick. Plenty of people running this and it does just fine.

My Grand Vitara's transmission shifts like new.
