The additive blends with ATF, offering instant results with no soak-in period and provides compatibility with HFM applications such as Chrysler ATF +3/+4, Honda Z1, Toyota Type T, Mitsubishi Diamond & Nissanmatic. It also incorporates synthetic base stocks, increasing lubrication and heat resistance properties to conventional ATF. Perfect for treating bulk purchased Dex/Merc, eliminates the need for more expensive / hard to find OEM fluids.

I am not for sure how much it helps, but I do not like to risk things on my diesel engine. So, I use it.

Added 1 bottle to my 06 Camry 2.4 L Automatic transmission fluid. Keeping in mind this particular car has had all normal maintenance and fluid changes it’s entire life. About a year ago I noticed the transmission shifting a bit sloppy and the fluid level was where it was when it was changed 25,000 miles prior, right between the add and full lines. I then added a bottle of friction modifier above at approximately 245,000 miles on the odometer. I can honestly state that after about 2,500 miles now since adding the friction modifier I’ve noticed a marked improvement in the shifting performance. Not as new or perfect but definitely better and help save ware on the friction bands.Just a note:Don’t use this in a CVT type transmission!However, many CVT transmission fluid is said to be life of the vehicle and that is not necessarily the case. Most CVT transmissions can be drained and refilled with the same amount of the correct fluid in order to increase the life of your transmission and override the planned obsolescence. See your independent auto care professional for information on this subject.

I have been using this product since at least 1999 and it has always performed as they say it does. I have yet to have a transmission or anyone complain about a transmission problem from the cause of this product and/or the fluid that I used to mix this with and I have been in business since 1996.

This product is awesome. I requested a transmission fluid change in Canadian Tire, and after that the shift got strange. When I took a look at the receipt I realized that the put the cheapest Dextron III oil they had. And my car has a honda transmission which requires Z-1. I was looking on internet for the Z-1 to buy and change by myself when I saw this product. So I removed 500ml of fluid as the fluid was over the limit btw, and added this bottle. The result was almost instantaneous. But got better after 20 mins driving. The s***ting now is like butter. I strongly recommend. And I saw that this brand has a Synthetic Transmission Fluid for my car. For the next change that will be the try.

I take care of my Honda Transmission, Its the original Automatic Transmission and I always use Real Honda ATF Z1 and now DW-1 Honda Fluid. However going from 1st gear to 2nd was a little hard shift when the car was COLD.. strange huh? Well I drained out a small amount of ATF fluid b.c I didn't want to overfill... I turned engine on and let IDLE while it was in Neutral as the directions said. Then put in nearly the whole bottle in Transmission. Then I went through the gears with foot on brake 1 2 3 4 R N Park... Then I pulled out of my driveway and it was instantly better I drove all over and would come to a full stop and I used to HATE to come to complete stops becasue the hard shift from 1st to 2nd but it was fixed instantly.. ALL ATP Products work and they are NOT SNAKE OILS... There ATP 205 Stop Leak is awesome, all their products will same you $ and the only place to find them is on AMAZON and for a great price.

Have about 3 weeks of driving now since the fluid went in and I am stillamazed. Looked for this product at several auto supply stores and only found itat Amazon. Thanks.
