Lucas Oil 10009 Transmission Fix - 24 Ounce (Pack of 12)

I poured the whole 12 oz bottle in after a quick check in the parking lot on my dinner break. Took maybe five minutes. No mess. By the next couple of drives, the shifting felt smoother and the little clunk I heard on hills got quieter. It is not magic, but it honestly makes the car less stressful to drive home in. One night I was crawling out of work after a rough shift, brain fried, and realized the car wasn’t doing that weird shudder when I turned left out of the lot. I noticed it because I didn’t have to brace for it. That moment alone made me glad I tried this. If your car is older and you just want it to behave a bit better on tired drives, this helps.

A friend, suggested I try this product, by Lucas, for my transmission, and it actually helped. It's worth a try, verses buying a new transmission. Suburban,would not back up , so I drained fluid and used this product. My transmission ,started going backwards again and it shifted smooth, going forward too.

When our beat-up gym van started slipping between gears, I grabbed this for the staff to use. I poured it in during lunch, then drove to pick up towels. Shifting felt smoother by the second stop. Cheap fix for now, and it keeps the van hauling weights and members around.

Lucas Oil Transmission Fix 10009 in the 12oz red bottle rescued my old daily sedan. My transmission had slight slip and hesitation when pulling away from stoplights, which worried me for my regular commute. I added it directly to my existing transmission fluid with no fluid drain required. After driving a short distance, the rough shifting and slipping cleared up. It also conditioned aging seals and fixed a minor drip, while helping keep transmission temperatures down. Perfect for family cars with lots of miles. I avoided expensive shop repairs. A must-have additive for anyone with a worn automatic transmission.

I used a bottle on my transmission and then drove 500 miles. Then I did a fluid exchange and drove another 500 miles and then another exchange and I added ludegard instant shudder fix and after 1000 miles my transmission no longer slips in 4th gear. It has 150k miles and had only one transmission service at 66k. I don't think my 2010 GX likes to go too long between services before it gets gummed up. This is hopefully a one time fix for me as I plan to service my transmission again at 180k. This is the process that some of the dealership use for the lifetime drive train warranty vehicles. They focus on keeping the fluids clean and conditioning of the internal seals without making them too soft. They're banking on you not keeping it more than 200k or much more than the typical 8 years. With proper care and maintenance you can get most vehicles to 300k and 15 years plus. My 2013 Avalon is at 182k and still operates silky smooth on the road. Almost forgot; this stuff is thick. I don't feel like I wasted my time or money trying it. I've also used other Lucas products on my older 2007 Tundra with excellent results. It won't fix mechanical issues, but it will usually fix or clean up minor issue due to fluid and seal conditions. Good luck.

When my ancient Honda started slipping between gears on the drive back to campus, I kinda panicked. My roommate told me to try this Lucas transmission fix before paying a shop. The bottle is small but I just followed the directions and poured it in after a quick Walmart run. shifting felt smoother after like two or three days of driving around town. I’m not pretending it cures everything, but for my broke college budget it’s nice. i can actually merge onto the highway now without the car freaking out, and that alone made me really glad I grabbed this.

Good fix for old school trans. Old school Ford C4, C6, AOD, and E4OD trans need a Mercon original blend. The new Mercon V fluids are too thin, they make the trans shift hard and can lead to slipping clutches on an older trans. 1-2 bottles of this fixes it.

The transmission on my 2003 Acura CL Type S sometimes "forgets" to downshift to 1st gear. After replacing the fluid, filters, and external solenoids, the "forgetting" still occurred. I eventually learned this indicates that gear's clutch is failing - the transmission will eventually need to be replaced. To delay the inevitable, I decided to try this additive. I didn't notice any difference at first. But after driving for a few weeks, the "forgetting" has become a rare occurrence. (I avoid full throttle in first gear because it always slips, even with the additive)

As a last resort before taking my car for potentially a full transmission repair , now i don’t think it’s the case anymore. As long as there’s no mechanical damage i said that it’s worth a try. Did a quick test drive and there is absolutely an improvement, not major as im guessing i should still drive a bit till the fluid reaches everywhere and i did only half a bottle, but i can see why it’s Sooo reccomended.

I observed that the transmission noise is somewhat quieter than expected. Aside from that, I have no additional evidence to provide. However, it's important to note that the liquid is quite thick, which means it takes longer to pour into the transmission or differential. Please keep this in mind. I brought one extra for Subaru XV rear diff. Hopefully make the rear diff quieter on the highway.

Works as advertised

The item was great

Bei meinem Oldtimer Mercedes 500 SEC tropfte nach längerer Standzeit das Getriebe aus der Dichtung der Primärpumpe. Zudem schaltete des Getriebe nach über 180 Tkm auch zunehmend mit Verzögerung. Nach Warmfahren des Getriebeöls füllte ich zwei Drittel des Flascheninnhaltes langsam ins Getriebe. Der Motor lief hierbei. Die Flasche hatte ich vorher im Wasserbad auf ca. 40 Grad erwärmt. So fließt die zähe Flüssigkeit viel leichter und schneller ins Getriebe. Ich habe nur zwei Drittel eingefüllt, da ich ansonsten überfüllt hätte. Darauf sollte man besonders achten, da Überfüllen zu großen Schäden am Automatikgetriebe führen kann. Hiernach habe ich die nächsten Tage bei längeren Fahrten ca. 200 km gefahren. Von Mal zu Mal schaltete das Getriebe besser um nun deutlich besser als vorher zu schalten. Signifikant besser! Und was noch erfreulicher ist, das Getriebe ist wieder dicht und tropft nicht mehr. Wie lange das hält kann ich natürlich noch nicht sagen. Hier vertraue ich auf die Erfahrungen anderer Anwender, wonach der Effekt schon länger anhält. Tolles Produkt, Daumen hoch.
