Leaks in the gearbox caused by hardened or brittle seals are prevented or remedied by using Liquid Moly's ATF Additive.

Using Liquid Moly's ATF Additive can extend the service life of automatic transmissions and reduce repair costs. Review: Fixed the shudder in my 2008 Mercedes ML350! - My ML350 is now 11+ years old and had developed a transmission "shudder". If I was going up a hill at local town speeds (35-45mph), it would make this shuddering vibration instead of downshifting. I could almost predict where and when it would happen. The first thing I did was do a fluid and filter change. Now I love Mercedes, but they marketed the 722.9 transmission as "filled for life" which is a crock of BS. When I drained the fluid, it was BLACK. Not good. I replaced the filter and stand pipe and, using the air compressor method pumped in about 5 liters of new fluid. Because my model doesn't have a drain plug on the toque converter, you cant get it all out unless you do a rather complicated flush. I figured, I'd do this change, then do another in a few thousand miles. It seemed to be smoother after doing all this (could be my imagination), but the shudder remained. Well, that fluid change in a few thousand miles turned into 2 1/2 years (best laid plans, etc!). All this time, that annoying shudder was there. So, a few weeks ago I finally drained and replaced another 5 liters of fluid (just a little brown this time), and I added the entire tube of LiquiMoly ATF. After driving for a day or two, the shudder is completely gone and she shifts like butter! Like the day it was driven off the lot! Now I realize this is anecdotal evidence. It could have been that the second 5 liter fluid change lightened up the fluid enough that it cleaned itself out or something, but I am chalking it up to the LiquiMoly. It was too dramatic a change for just changing half the fluid. Your mileage may vary, but I am sold. It gave my transmission new life!

Or do you add tobtransmission directly??** A: OK in this case it all depends. So if you have not changed your transmission fluid in 35,000 to 40,000 miles you should drain your fluid and add new fluid and then add the Liquid Moly. Note if you do the drain yourself only 1/2 of the fluid will drain out as there will be 50% of the fluid in your torque converter, and to drain this out you would add new fluid back to the transmission drive it for a few miles and then drain it again and re-add thus most of the old fluid will be removed. Note never overfill you transmission fluid so say the Liquid Moly is 160z half a quart you would need to put have a quart "less" of transmission fluid again NEVER over fill. If you don't drain the fluid yourself and take it to the shop they will know what to do. So change yourself see above, add yourself to existing fluid drain 16 oz and then add Liquid Moly. NOTE never add the this additive to a CVS transmission I.E. Nissan-Infiniti or again ANY car that is a CVS transmission!!!! Hope this helps. **Q: The bottle said that it works for type ii and iii atf. would that work for 2002-2006 toyota camry as it uses type iv atf?** A: Here is the info around ATF 4 vs ATF 3. +4 is now the recommended fluid. +3 came up to 00. The transmission isn't going to self destruct if it has +3 in it. +4 was designed to perform better over a longer peroid. From allpar: +4 is now the recommended fluid. . The transmission isn't going to self destruct if it has +3 in it. +4 was designed to perform better over a longer period of time. The goal in developing ATF+4 was to create a fluid that would match the performance characteristics of the current fluid, but would retain those characteristics for at least 100,000 miles. Research papers specifically note that the anti-shudder properties of ATF+3 are usually degraded enough by 30,000 miles to cause noticeable shudder. So basically ATF +4 will work with this product as ATF+3 and ATF+4 are basically the same except ATF+4 lasts longer. Note if you are using this product and you have not changed your transmission fluid in a long time say 50,000 miles or so you should do so as this product works better when you have new-clean transmission fluid. **Q: Can I use this with honda atf dw1?** A: DW-1 is excellent for your Honda - and very reasonably priced. Stick to the DW-1 but do a 3x drain and fill on your trans. **Q: Funciona en cajas cvt outlander 2016?** A: No, it is not suitable for use in CVT transmissions. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fixed the shudder in my 2008 Mercedes ML350! *by P***L on December 12, 2019* My ML350 is now 11+ years old and had developed a transmission "shudder".

My 8L90 with the shuttering torque converter comes back. I flushed and replaced trans filter. Topped off with the Mobile 1 blue label ATF with the Liquid Molly and fingers crossed it runs great at 81k Miles. Recommend changing or flushing then add Molly with new ATF. ## Frequently Bought Together - LIQUI MOLY ATF Additive | 250 ml | Oil additive | SKU: 5135 - LIQUI MOLY Oil Additive Cera Tec 20002 Ceramic Wear & Tear Protection for Petrol & Diesel Engines Smoother Engine Performance, Less Friction & Lower Fuel Consumption 300 ml - Liqui Moly Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2037 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/5924122-liqui-moly-atf-additive-250-ml-oil-additive-sku-5135](https://www.desertcart.us/products/5924122-liqui-moly-atf-additive-250-ml-oil-additive-sku-5135) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
