## Overview

Mobil 55221 3309 Automatic Transmission Fluid is a premium lubricant designed to meet JWS 3309 and GM 9986195 specifications, delivering exceptional thermal stability, wear protection, and smooth shifting for slip-controlled lock-up automatic transmissions. Its advanced formula controls friction, reduces shudder, and resists oxidation, extending transmission life and ensuring reliable performance under diverse driving conditions.

## Description

Mobil ATF 3309 is an exceptionally high performance lubricant that meets original equipment manufacturer's specifications for use in certain slip-controlled lock-up automatic transmissions. Mobil ATF 3309 is recommended for use in transmissions requiring fluids of JWS 3309 or GM 9986195 quality levels. It is also recommended for service fill applications where Toyota T-IV or T4, T-III or T3 are called for. Please refer to the owner's manual for proper fluid requirements. The unique formulation of Mobil ATF 3309 is designed to provide excellent lubrication of transmission in specified slip-controlled lock-up automatic transmissions. These outstanding performance capabilities translate into significant operational benefits, including: Excellent lubricating characteristics for quiet operation and smooth shifting in approved transmissions, controlled friction properties for smooth and efficient transmission of power across all normal temperature ranges, helps to control transmission shudder and provide excellent vehicle drivability, helps to extend transmission life based on excellent wear control, long fluid life based on excellent oxidation resistance, excellent viscosity stability (high viscosity index) to help assure adequate lubrication without excessive thinning in severe high-temperature service or thickening at low starting temperatures, resistance to foaming, super protection against rusting and corrosion, compatibility with synthetic rubber seal materials. Automatic transmissions should be checked for proper fluid levels at regular intervals, and the fluid should be changed at manufacturer recommended intervals. However, this may vary due to your vehicle's operating condition. Some manufacturer's recommend more frequent changes of transmission fluid under severe driving conditions, such as heavy traffic, hot weather and trailer pulling.

Review: Ultimate Protection and Unbeatable Bulk Value for the DIYer - 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.
Review: Mobil JWS3309, Automatic Transmission Fluid, for Volvo's - Been using this Mobil Specification JWS3309 Automatic Transmission Oil required for Volvos, in this case a 2006 Volvo S40, with 150K miles. I change the fluid once a year by draining the pan, no gasket or pan removal since this is a sealed transmission. Even though Volvo says the fluid doesn't require changing, rest assured the fluid oxidizes and turns black with all that grime from constant metal friction and heat generated by many miles of usage. For a complete transmission flush, drain the pan, about 4qts. and refill through the transmission dipstick tube, with a plastic tube hand pump, the same amount as removed. Run the motor a few minutes and cycle by repeating this process FOUR times until all 12 qts. in the package are used up. Before the last top-off I also add and highly recommend a bottle of Prolong Automatic Transmission Treatment. Through the years I have had no problems, no leaks, no smoke, no hesitation, in fact the motor and transmission runs good as new. This Mobil 3309 ATF is pure mineral based oil, not semi-synthetic. This is NOT MOBIL 1, which is a pure synthetic ATF and is NOT compatible with JWS3309 specifications like the regular Mobil 3309. STOP confusing and using Mobil 1 which this oil is NOT, only the brand name. Several companies now make ATF that is JWS3309 specific, as required by Volvo. I have used and highly recommend, this regular Mobil 3309 for many years with no problems, read your owners manual, using anything else is at your own risk.

## Questions & Answers

**Q: 2004 saab 9-5 aero can i use it**
A: Yes, this is what Saab 9-5 requires, any JWS-3309 approved fluid is good.

**Q: This is the fluid for my 2001 Volvo S40 Turbo, synthetic, right?  Thanks.**
A: My research suggested Mobil 3309 is an exact replacement for the expensive Volvo brand transmission fluid.  I drained and filled the transmission on 2007 SX70 with no problem.  Robert

**Q: 2006 volkswagen bug... will this fluid work**
A: Sorry I honestly do not know... I only know it works for Volvo AWD models.

**Q: 2013 mazda 6 with a 3.7 litre engine.  will this work for the atf?**
A: Check your owner's manual for recommended fluid type.  Then check Mobil's website to see if the 3309 is compatible based on Mobil's info.  Type 3309 is a special fluid but very good. I used it because my car has an Aisin 6-spd FWD trans and meets the Ford specification for fluid.

### ⭐⭐⭐⭐⭐ Right price, right stuff!
*by C***. on October 17, 2025*

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.
