I tried this stuff, and had an unfortunate coincidence make me think it was horrible, I was wrong. I find it smoothed out my shifts, and generally has been impressively good at helping out a tired old transmission. In my original (wrong) issue, I had my front end front wheel drive vehicle have its lower control arm bushing give up and get soft coincidentally with using this stuff, and I blame weird steering issues on the fluid... not.) After fixing the control arms, I found that this fluid really did smooth out the shifts, and its easy, just poor in a bottle. (I recommend a full drain, including torque converter fill and flush. (e.g, drain your system, refill, then disconnect a line at the cooler, and with a helper run the car in park filling fluid in concert with draining fluid. This empties the old fluid from the torque converter and transmission oil cooler. When all the fluid is new, then add in this magic additive.) Helps quite a bit on an older transmission to smooth out shifts, get rid of judder, and help prevent minor slipping that has just begun. (Nothing can help major slipping that been going on for a long time..., except a rebuild.)

I have been having problems with my car on mornings. When sifting into drive to move, I use to have to rev the engine for at least 5 seconds before the gear would engage. Reverse gear was the same issue. Several mechanics told me that it was the transmission bands that may need to change. One told me to put in an additive that didn't make a difference. Previously I drained and refill the transmission fluid, no change. So I came across this product while searching through amazon, read the reviews that were mostly positive, I decided to give it a try. I bought it along with the transmission fluid to refill. I put in the new transmission fluid then put this in. I let it sit for awhile, started the engine let it warm for about 15mins then decided to go for a drive. When i put it in Drive, the car engaged with little delay was still skeptical but hopeful drove a bit change the gears. It seemed to be changing smoothly enough. But the real test is normally on mornings. Got up the morning warmed the engine and shifted to Drive, the engine immediately engaged I was really surprised that it actually engaged so sudden. Drove it forward then tested the reverse gear, engaged without having to rev the engine. I have been monitoring all the places that when parked up that the engagement had been delayed and so far it has been engaging without delay. I only had to use half the bottle for 4L size transmission pan. I believe that this product has worked in my situation.

Having a car dealership/mechanic shop we’ve put this in an array of cars. Sometimes it works, sometimes it doesn’t. I think it has to do with how far gone it is more than the make/model. Though some have felt beyond help and it has helped, others had very minor issues and it didn’t help so idk. Seems quite random. But it is usually the first thing we do if a customer reports hard shifting before we suggest a rebuild or replacement. Usually at least buys them a bit more time.

I’ve used their products before and have had success each time including radiator and head gasket. This time was a small leak in the transmission fluid plus very hard shifting from park into reverse. Both problems were solved! I’ve never had any issues with their products, they always work, and are very easy to use. I’ve saved a lot of money using them.

Transmission was slipping and hard shifting really bad and didn't have much usable life left in it.Bar's definitely had a noticeable effect on the hard shifting and is mush softer now (but still noticeable).Ultimately I will need to have the transmission rebuilt, but this "quick fix" hasdefinitely extended the time till it fails completely.

My Acura TL project I bought had a VERY worn transmission. Tried reviving it with OEM filter and fluid but didn't help too much. Initial fluid was super crispy and stank so bad! New fluid was WAY better but needed more gusto. Had issues with slipping, searching, in out of gear, loss of power, high rpms with no movement... Then THIS! Used a bit more than directions said and after a little circulation idling and then driving a little, WOW! It can actually take some spirited driving now!
