  • The vaccine for your transmission!!!
Size: Automatic
2006 Honda civic hybrid cvt had the hardest shudder from take off it would shake the entire vehicle that how bad it was this vaccine was my last hope before the pulling it and it worked better than any additive I have ever used immediate results. Transmission is shifting amazing now no shutter absolutely ever 10 out of 10. Recommend this product. Also, all the bad reviews are because they have probably major mechanical damage. This is obviously will not fix that ... show more

  • It worked exactly as it said it would, surprisingly
Size: Automatic
Update: I just hit 133k miles and the transmission is literally like new. It's silent and shifts perfectly smooth. I am getting 37mpg average now because whatever metal->metal friction it had is gone in there. It coasts silently and is smooth and easy to accelerate. I'd give it more stars if possible. Now to put more miles on the other cars to work the product in; I only drove them about 700 miles each before parking them. More miles seem to make it work better! 130k miles on my transmission but only 12k on the 3rd motor (hyundai) and the shifts started to get loose and noisy- I could hear the drum coming to a stop in reverse and 3rd gear after having the dealer service the transmission. Looked around and found it to be normal with age but it was driving me nuts. Came across this product, added it at 129,400 and figured who cares if it doesn't work: well it worked.l exactly as it said it would. Not only is the noise reduced by about 80%, the shifts are smooth and downshifting doesn't slam into 2nd gear anymore. At 131000 miles I noticed it most; it feels tight, smooth and quiet and I honestly forget about the noises it had sometimes. I keep listening for the metal sounds and the low slow hum of the drum being stopped and all of that is near impossible to hear unless you're specifically waiting for it. Thought maybe I'd try it in my jeep and wife's jetta and sure enough the jetta doesn't whine in 1st anymore and my jeep doesnt slam into 3rd when braking anymore. Best additive I've ever tried. I do recommend and have recommended this exact product to my family after my results. Try it yourself! Adding it is tricky on the jeep and VW but the Hyundai was super simple. ... show more

  • Great product but container packaging need improvement
Size: Automatic
I like Xado and it work well in my transmission coating it for a continuos lubricant. But the syringe which contain it have a circular ring notch which could impeded on the amount of ex120 output into your transmission or could it be an indication of very little ex120 contained in the syringe. Like a clear syringe to be able to see how much ex120 is inside or left. ... show more

  • I still could not beleive it
Size: Automatic
I used this on my 2005 mitsubishi montero limited and i must say it really improved the shifting and lessened the vibrations. Bought this suv last year and was starting to regret it. For some reason shifting was a bit late and there were some vibrations before shifting and OD was not locking at highway speeds. I tried everything from a complete tranny flush with OEM fluids to the Dr tranny red tube (also bought herein amazon) with no significant improvement. Then I heard about this product from a friend and i thought why not try it. If it didn't work i was going to let go of this truck next year. Man was i surprised. The first i noticed is that it started shifting @ 2k at normal driving speeds (good on gas) and during downhill drives it started its usual downshift when it senses the speed increase after letting your foot off the pedal. Od started to engage without getting kicked out once you loosen the accelerator pedal. I was in disbeleif that only after 2 days of driving this thing has started to improve my car. Then at 400 miles i started to notice the symptoms coming back. "too good to be true.." i said but then i read on the packet (i tend to keep stuff around until spring cleaning) that if the symptoms do come back then you may need to reapply another tube. So i said what the heck and bought another one. I dont know what the previous owner did to this vehicle so i assumed it must have been really worn down. As i put the next tube it crossed my mind that i maybe this was just all hype and that they wanted you to keep buying often, so i said to myself that this would be the last tube. If it doesnt work then this car needs a mechanic to get things right. Well its been 600 miles after the last tube was put in and all i can say is that every day it started improving even more. i just hope it lasts me another 65k miles as the product claims it protects you. Will update if anything weird happens... ... show more

  • Really does noticeably help!
Size: Automatic
Much like anyone looking into this product, I was highly skeptical it would help. But, I am here to say it does! I have an older 09 Pontiac G6, with about 162k miles, and it has been relatively well cared for. It was mostly driven on the highway, so while the mileage is high, it is actually in better condition than most I see these days. Unfortunately for me, it is only the 4-speed auto, which is to say, all I can really sum it up to, is that It works. It too is not in bad condition, but you can most definitely tell it is high mileage. It shifts fairly hard, and can not always make up its mind on what gear to be in, or shift fast enough when needed, but overall its fine. These traits are not too far off from brand new I might add, but annoying none the less. So, I decided that it was time to try something to just help it along. We put more money into getting it fixed up than KBB tells me its worth, so needless to say I really don't want to spend more than is necessary in its late age. I've used Xado before in an old Subaru and it helped, hoped this time was no different, and thankfully that is the case! As soon as it came in the mail, I put it in the car, and within a couple of minuets could feel the difference. The shifting was smoother, with less jutter, and less hesitation than I was used to, especially when accelerating onto freeways or for passing. It just seemed to be happier, if that makes sense. It has now been a couple months, and while I still feel it has helped, I have noticed that it is more back to "Normal" now. I plan on ordering another syringe in the near future, as they recommend an extra if your transmission is old, or if it holds more fluid than what one syringe would help. I can still tell that is has helped however, as the shifts are more pronounced, without as much strain it seems. My hope is that it really does help repair and clean some of the metal surfaces and such, I have no way of proving or showing this however. Overall I recommend this product to anyone who has an older car that just needs a little extra help! ... show more

  • Lucas is better
Size: Automatic
Used 3 in a 06 Volvo XC90. The valve body’s are known to have problems wearing down in these so I decided to give this a try before I have it replaced. The reason I chose this product is because it says it repairs metal. My symptoms were hard 2-3 up shift that was noticeable when cold almost went away when driving on the highway but in stop and go traffic or idling for awhile it got a lot worse. When it got really hot it would sometimes flare up when going to 2-3 then clunk into 4th. If I keep airflow to the cooler it does a lot better. Also when it got warmer I would get a hard 3-2 downshift but was almost nonexistent when airflow was good. I realize that it is a very temp dependent issue but after lots of research I found it’s the valve body wearing down. Before I added it I changed all of the fluid with oem fluid and reset adaptations then drove for about 1000 miles to see if there was a change. It was slightly better after fluid change so I decided to add this to see if I could make it better. It got worse for awhile at first and I thought I messed up and was regretting it but I kept driving it. After another 1k it got maybe 10% better than it was before. I really didn’t want to pay for the valve body yet so I decided to drain some fluid out and add a bottle of Lucas and made sure the level was correct. The Lucas made it about 50-70% better but it still didn’t like the heat. I drive a lot of highway miles and it’s perfectly fine on the highway but after 30 min of stop and go traffic it starts to shift harder again. I realize that I have damaged parts and there is no magic potion to fix that so it was basically a last ditch effort. I feel that a lot of the reviews aren’t based on results but instead of what’s in people’s heads. If you are trying to get that last bit of life out of your transmission I’d go with Lucas because I’ve always had good results with it. It’s also a lot cheaper than this stuff and even if it doesn’t work it’s less money wasted. ... show more

  • New power to the rogue
Size: Automatic
I was feeling pretty desperate with my 2016 Nissan rogue ,shuttering transmission and very slow take off at stop signs,ect. Was thinking I was going try something else before new transmission. I did 1st treatment and after 1 minute of driving it started jerking a bit ,then 5 minutes more of driving the shutter was gone. It came back about 200 miles later,a little. After 1500 miles of driving,u added a second syringe. The rogue is shifting so smooth and great pick up . I would say after 2500 total miles and 2 syringes,1500 apart. The car drives better than when I bought it at 79,000 and now it has 204,000 miles on it. It had 189,000 on it when I did first treatment. I wanted to wait to leave review to see how treatments performed. Fantastic product!!! I also bought the engine additive and did 2 rounds of 3 syringes each,500 miles apart. I had another if vibration in the motor , thinking it needed motor mounts but they were good. The engine treatment took care of 95% of vibration when it's idleing at stop sign. Sorry for the long review but loots to say about their great products. Thank you ... show more

  • UPDATE
Size: Automatic
So far my transmission has no more stutter at low speeds like prior to putting in product. If I was to do a slow roll to stop sign then gas it before stopping I would get a stutter but it’s been 2 weeks so far and hasn’t happens since. *** UPDATE*** took away 2 stars bc the shutter came back maybe lasted 3-4weeks, I’ll try another tube and see if 2 tubes does the trick but it can be a quick fix to sell the car ... show more
