Bought vehicle used and had set barely used for about a year, ran great but transmission seemed to have to warm up to kick in, added this and seems to have lubricanted the seals and improved ease of shifting and driving.

Bought a used car transmission fluid was never changed. Added this and all my shifting issues that was making the car sluggish worked changed the transmission fluid first!

I use Zmax engine, trany and fuel additives all the time in my 2012 Dodge Ram with the Hemi which has over 264,000km on it! And this Hemi still runs and performs great! I've been using Zmax for years for all my vehicles and it has never let me down! My vehicles run forever! I add these additives every 2nd or 3rd oil change...I add every 2nd oil change since it rolled over 250,000km! This stuff doesn't just coat the metal like all other additives, it soaks into the metal which makes it last longer and run smoother!

I have a 2016 Taurus SHO with about 80k miles on it. I drive it hard and it does not disappoint but the shifting has always been hard since I bought it at about 30k miles. Not broken hard or a problem but I always wished it would be smoother especially on the downshifting when slowing down. I added this on a whim about a 100 miles after a transmission flush and am so glad I did. I noticed an immediate (within 20 miles) change in the shifting for the better. It is so much smoother and the downshifts are not nearly as abrupt, in fact I'd call them enjoyable. Best $17 I've spent on the car beyond a doubt. I highly recommend this product.

Helps to slick up transmission to send more revolutions to the wheels . Helps smooth out transmission. I have been using zmax for years and have only had good results like the engine runs about 15 degrees cooler.

We have a 2014 GMC Acadia with around 109k miles. We purchased it used and when i got it i noticed the trans fluid had yet to be replaced. So i did a flush and the transmission improved 90%. However, 1 to 2 and 2 to 3 was a little hard shifting, not bad but i knew it shifted smoother than what it was doing. So i got ZMAX which ive used before in my oil, but never in a transmission. Needless to say it cleaned the shift points up perfectly. After driving around for about 30 min it was already shifting snoother. After my wife drove it back and forth to work for a couple days its now like new. Super happy with this product. This is not a product thats going to fix mechanical issues. But i believed my issue was just a varnish issue around the solenoid actuators where the oil had not been replaced. GM recommends every 40k miles on trans oil. So yeah if your having a little harder shifts then your used too. Get this and it will clean it up. You dont need to pull any oil out, just add the product and drive, its that simple. In about 1000 miles the product will fully soak in to all the metal and clean and lubricate varnish points. This product is not designed to fix worn out trans parts. So dont bother because it will leave a bad taste in your mouth. It simply soaks into the metal, allowing varnish or carbon to not adhere to the metal services. Look into Prolong or Bestline products if you need to treat a worn out transmission.

I can't say this formula cured my transmission problems long-term, but it helped get rid of an engine code and made my car shift a little quieter. It's super thin (like water) which surprised me
