I've used this stuff for 20+ years and it really works

If you change all of your trans fluid at once you can cause major leaks. A solution I came up with years ago was to use a fluid extractor to pull 2 quarts of fluid out through the dipstick once a year and replace it with fresh fluid. Every other year I pull 2-2/3 quarts out and add one of these with 2 quarts of fluid. I have put as many as 270,000 miles on multiple transmissions without a single repair or issue. This includes my friends, parents and siblings cars, imports, domestics, front drive, rear drive etc. (about 20 cars). Unfortunately most transmissions made in the last 10 years or so can't be easily serviced at home as they are sealed systems with no dipstick. Another reason I will never buy a new car. My cousin had a chevy minivan with 220K on it and the transmission was starting to slip. The fluid was brown from lack of maintenance (should be red). We did the 2-2/3 quart change out with one of these and within a few days the transmission was back to normal. We did the same thing a month or so later for good measure. The transmission lasted another year and a half with no issues when the engine finally gave out. That is the only time I used it for repair instead of maintenance and it work brilliantly. All he was hoping for was a couple of months so he could save up for a down payment on a new car.

This is the only transmission treatment that I would trust to use, and it works

I'm not usually a fan of transmission fluid treatments, never have been. Transmissions are the most complex and precision pieces of mechanical wizardry on a vehicle, and they are rather particular of what you feed them. I've always used strait ATF of the proper type and a quality brand with regular fluid and filter changes. I decided to try this stuff for a couple of reasons. One I just bought a used 3/4 ton with around 160,000 miles on it with the original transmission. It has been serviced as the fluid looks good, but it's a little lazy on shifts and just not a smooth as it should be. I read a ton of reviews before pulling the trigger on this and as they were almost universally positive, I figured it could not hurt. I bought the truck right, and at that mileage on a hauling truck, if I nuke a transmission, I'll put one in. I would also trust a Lucas Oil product before any others as I have always had extremely good success with everything Lucas and they do one thing, they make oils and additives, meaning they know what they are doing.I did a complete fluid flush and filter change. This was made easy since the truck has a aux cooler in the front, just pop the QD lines off and add some 3' hoses (since you cannot be certain of which is supply and return, less risk of mess) into a 5 gal bucket. 4 gallons of Dexron 6 later and we have a transmission full of fresh fluid. I have not yet driven the truck any distance real, but after adding the treatment and letting it get all mixed into the system, I can already tell that things feel better, it goes into gear faster and smoother for sure. I expect this will continue to improve as I drive more and the additive continues to permeate the system.Update:I have to admit, the skeptic in me has been proven wrong with this stuff. I've put over 1,000 miles on the truck since flushing the transmission and adding this treatment. Most of this driving has been towing a trailer too. All of the shifts are much firmer than they were before, the 2-3 shift used to be very lazy but now it's snappy, like it should be. Down-shifts and up-shifts are all feeling better. Does not feel like a tranny with 160,000 miles on it at all. I will be adding this stuff at every fluid change, which I do far more often than the manual says.The manual says 100,000 miles for transmission servicing, with Dexron 3, it's more like 30,000 miles max in my experience if you want to have a transmission left at 100k. With Dexron 6, probably more like 50,000-60,000 miles or so, not positive since this is the first go round with Dexron 6 in one of my vehicles. Towing a lot always decreases the fluid life, so best advice I can give is to monitor the fluid condition carefully, and change it when you have any significant darkening and before it starts to burn. Fluid isn't cheap anymore, but it's a lot cheaper than a transmission...This stuff will not fix a transmission with a serious issue, treatments cannot fox broken parts or excessive wear. What this stuff does do is recondition seals and friction discs, this will fix minor slippage due to age and normal wear, it will also fix the lazy shifts caused by worn friction discs. For the price, it's certainly worth a shot, but don't knock it because it does not help you, this is designed to help transmissions that are still fully functional.Update 2:7,500 miles in and things are still smooth as silk.Update 3:10,000+ miles in and the transmission feels almost a smooth and solid as it did when new (I did not have this truck new, but I've driven a lot of them with varying mileage). Fluid is still bright red and not showing any signs of breakdown, which is what I'd expect at this point. Like I said earlier, I'm not a fan of most pour in "fixes", but this one really does work, assuming your transmission is still in working order. Even if it does nothing, it's a cheap attempt.

Seems to work.

I add a little to the transmission when the 1-2 shift gets harsh. It seems to free up the 1-2 shift valve.

I like most products I have tried from Lucas. I have a 2015 Camry 2.5l non hybrid that at about 120k miles I noticed the first few gears would shift a little harder especially when the transmission wasn't to temp yet. The torque converter seemed to be running a little rougher. (you could feel it in the gas pedal when accelerating and when at a steady speed.) This is a known issue with this transmission as well. To give some detail I have changed the filter and fluid every 30k miles in this car. Toyota didn't include a dipstick so in order to do the drain and fill correctly you have to put a little extra in it, bring the transmission to temp 104-110 degree F. Then drain until it trickles. Normally you only need about 3 quarts to accomplish this. Knowing that there is about 3.5 more quarts in the transmission I decided I would try this but use 2 quarts of this. I drained the oil, changed the filter and put 2 quarts of Lucas in it, then put 2 quarts of my premium trans fluid from a reliable manufacturer. Then I brought the transmission to temp, and drained to a trickle to make sure that the transmission had the proper amount of fluid in it. I immediately noticed improved shifting especially in the lower gears. The next day when it was totally cold I notice improved shifting especially in the lower gears again. Fast forward to 1000 miles later and I can't believe how smooth the transmission is shifting in all gears at all temps, and there is no roughness in the torque converter at all! It's back to how the car was when I first got it. I am probably going to use 2 bottles of ATF and 1 bottle of Lucas at every 30k now because I am sold on this product like the other Lucas products I have used.
