I receive this transmission slip stop about 4 months ago. My husband used it on a Ford truck, just to try it out. At first glance, we thought that it might not make a difference in the transmission performance, due to past experiences with similar products; however, it did work as intended. It has been three months since we first use it, and we have not needed to use it again.

So far my experience with K Trans-X Automatic Transmission Slip-Stop & Leak Fix is great. We have an older (2005) Mazda 3 and my husband noticed the transmission started to slip not to long ago. After using this product, the transmission is noticeably smoother. I would recommend this product to anyone having a problem with shifting gears or leaks.

First off I will state that I did receive this as Part of the spark program! 2nd this is my honest review! At first I was a bit iffy to “test” this on my 05 BMW X3. Only bc we had already tried a different type last yr{2019}, that worked but didn't last long at all! I believe it was maybe for 1 month if even that! So I was worried about trying another! But we followed the directions & initially I must admit after driving for 5 mins I was ready to go home bc nothing was different! Obviously this has been frustrating so I just needed it to work ASAP haha! But heading home it was around the 15-17 min mark.... we stopped to grab a drink. I turned off my car, went inside & when I went to pull off there was definitely something different! So much that I just looked at my husband to see if he noticed bc he's not in my car as much As I am! && His truck is rough so either way he says my car is smooth driving! But I promise, it had grown not to be!! But he actually noticed & wanted to drive to feel it better!! & I could even tell the difference from sitting in the passenger side as well! & rather quickly! Driving it away and hitting stop sign after stop sign It continued to go smoothly even more as we drove!!! I went around a few blocks extra to make sure I wasn't going crazy!! Lol. I've waited to do this review for almost 3 weeks to give my honest opinion on how this Product worked in MY car! Still to this day I have huge hope & confidence bc my car is normal again and has no leaks! As of right now I do give this product 5 star!! Remember— Don't give up too soon! Drive it for at least 20 mins, I'd say, just to give it that time it needs to do its thang ;) you may be surprised/excited on the outcome as much as I was!!

This is something that I would have to rate over time. I wish I could do an update with more time. I actually took a little time to make sure this was used correctly. I have no issues right now or feel like the product isnt working correctly. So far so good.

I have a 2004 dodge 2500 With 285.000 miles. I had a little Rough shifting into second and I used the k-trans x transmission Slip and stop leak .. This would be a Good product to add as maintaining an automatic transmission, I think It has made shifting easier... check fluid level before adding because You shouldn't overfill transmission fluid. If you are low already this is the product You should try.
