Great Product
From Ernest Gorog jr of ELKTON, Maryland on .
Found this product to be very helpful in easing the transmission ability to shift smoothly.
Fantastic stuff
From JB of Austin, Texas on .
I got this as an add-on to the 4-fluid treatment offer on the ZMax website for my mother's 2005 Camry. I poured in the fluid and immediately the transmission felt tighter, like the shifting was originally intended. It shifted more cleanly, no hesitation. So I went and bought the Engine and Fuel treatments, poured those in just after an oil change and now it's driving like a brand new car. I love this stuff. I use it on my 4Runner and it did the same thing - truck runs like new. Cheers!
Works like a charm
From Anonymous of Portsmouth, Virginia on .
zmax transmission treatment always performs whenever I use it. It always makes my transmission works better than before.
I'm impressed.
From Dale Hyman of Baraboo, Wisconsin on .
I put the transmission Formula in my Nissan Marino. They don't have a shift like most cars.. mostly un-noticed. Mine started shifting and it was noticeable. Due to the virus my repair shop closed. I put in the Trans Formula and in 2 days it was back to shifting like it's supposed to. This stuff works great. Can't wait to put some in after the trans gets serviced.

Highly Recommend
From Eileen of Allentown, Pennsylvania on .
Purchased the Transmission formula and had my mechanic add it and drove 10+ miles and noted an improvement in shifting and also used the additive for the oil and gasoline, all with noted performance improvement. My car has that extra "kick" when I need to pass on the highways with confidence and no hesitation at all. Planning a move to NC, fluids are being changed, Zmax added to keep the performance level. Can't wait to try the Wax formula and see the results. Great product, will keep using it.
ZMAX TRANSMISSION FORMULA
From Tim of Yorkville, Illinois on .
I have used this product in the past to eliminate slipping and hard shifting when car is cold and it works. I tried other anti slip additives but they didn't work. It is hard to find and was told by Zmax that you can use 6oz of engine formula in the transmission.
Quieter tranny
From B. Bonnett of Mobile, Alabama on .
I want to tell you guys - your stuff is tops. This is Bob. I'm 55, have owned over 3 dozen cars in my life -can name em all, and have tried multitudes of various additives for different things. Yours is the very 1st I've ever bothered to contact and compliment. In December 2015, I purchased an 89 mighty max truck. Noticed it had a hell of a tranny noise in 1st, 2nd, 3rd, & 5th gear (never 4th). But I loved the truck and bought it. I changed the tranny fluid and added your zMAX tranny formula. Right away the noise decreased and has gotten quieter every day I've used it since! I'm amazed at how well and fast this stuff works and would recommend it to everyone. Seriously good stuff guys. Kudos and thanks for providing a product that actually does all it claims. One very satisfied customer. Thanks.
Best money spent!
From M. Ray of Dover, Delaware on .
First off, I have never been impressed enough to contact a manufacturer about their product until now. Finally a product that actually works better than expected. Wow! Out of desperation and much study I decided to try your transmission additive for my 124,000 mile GMC Sierra. My transmission was shifting very hard with noticeable clutch shuddering. Within 10 minutes of adding your product to my transmission I started noticing a dramatic change in shifting smoothness. The same result was achieved in my son's high mileage Altima. They both now shift like new vehicles again. Amazing! I was so excited that I didn't have to spend money on a rebuilt transmission that I told all my friends at work about my success with your product. Thanks for your amazing additive! Best money I have ever spent! It was particularly helpful to me since I need my hard earned money to get my youngest through college. Thanks again!
Response from zMAX: We love hearing how zMAX helps our customers!
Amazing!
From K. Langstaff of Grayson, Kentucky on .
I own a 2009 Ford Taurus with 125k miles. The transmission began acting up: hard shifts, not downshifting, slow shifting. Being as that the Taurus has a sealed transmission, I was looking at either a major overhaul ($$) or a new tranny altogether ($$$). A mechanic friend of mine suggested adding a bottle of zMAX. I gotta tell you, I was a little hesitant because I had added another transmission additive (rhymes with pea phone) and it didn't do anything. Boy was I wrong.
After a few days, I noticed a definite improvement. The transmission is back to normal! I haven't had any episodes of hard shifting or a failure to downshift since adding the zMAX. I don't often recommend products, but I'm making an exception. This stuff is amazing!
This stuff is Great!
From T. Vest of Raleigh, North Carolina on .
I just recently purchased your products for my two vehicles. I saw an episode on Truck U where one of the hosts went to your raceway and told the story of your products. This convinced me to try your products. Well, as I said, when I received the products, I first used them in my 2008 Ford F-150 FX4 which has 85,000 miles. I immediately noticed that the power steering does not whine anymore, and the transmission shifts like it did when it was new. If the fuel and engine treatments work that well I'll be delighted. I have since used the treatments in my wife's 2004 Ford Explorer. This stuff is GREAT! I'll be back!
Awesome product!
From J. Casha of Manalapan, New Jersey on .
I bought zMAX Transmission Formula for my Lexus ES 300 2003. The 1st gear of the transmission was slipping and creating a disgusting noise. My mechanic recommended to replace the transmission. I decided no (195 000Km); added zMAX and 3 hrs later no more noisy transmission. This product is awesome!
