        Comments about K & W Chemical K&W Automatic Transmission Slip-Stop and Leak Fix:

        I have never written a review on a product until today. I was reluctant to purchase this product, as a rule I purchase Lucas products first and foremost. I read the reviews on this product and decided to try it. Let me say this, for a day my transmission was skip shifting, slipping and not downshifting. I put this in, and placed vehicle in reverse. I then backed out of the driveway, placed into drive and it slipped for a second and BAM it was instantly as if I had replaced the transmission! NO JOKE. It has been running perfectly for three days so far. I am totally impressed. The leak has also stopped after about three hundred miles of driving. I will purchase this product again and again.

          Have used it in 4 vehicles, to resolve slippage, a stuck valve and sluggish shifting. One of the best products of any kind that I have ever used.
          More people leed to know about it.

            I was quoted $1300 to repair a transmission. I decided I would try Trans X and replace filter. I changed the transmission fluid and filter an added Trans X. I used the car 2 more years without any further transmission problems. It is the only Transmission additive I will use.

              I have a 1997 Mercury Sable that was shifting in and out of overdrive and would shift hard in to second gear sometimes.I changed the filter and fluid and added Trans-X. The cars transmission is shifting smooth and has not jumped out of overdrive lately.

                  Can this be safely used in a 2006 Chevy HHR with the 4T45E transmission?

                    A:

                    I'm happy to help, Sticky Transmission Solenoid! Your 2006 Chevrolet HHR with a 4T45E transmission is designed to use Dexron VI or equivalent ATF and no additional additives are recommended by GM. You may be able to free the sticking solenoid by removing it and cleaning it. The solenoid could need to be replaced as well. It is normally located inside of the transmission pan on the valve body. Or, if it's been some time since your vehicle's last service, it would probably be a good time to have the transmission fluid changed.

                    If you need additional diagnostic help I suggest checking with a mechanic. Try our 'Need expert help?' link further down this page if you need help finding one.

                • Q:

                  My tranny on my '03 Chevy Venture sticks/slips, however it is not leaking. The first few miles of driving, it stuggles to go into first gear and when I come to a complete stop, it feels like it's loosing pressure somewhere and it gives of a thump when I let my foot of the break. I just flushed the fluid six months ago and while it slighlty improved since, my fluid is now brown again. If I flush it again, Will this product fix the sticking/sliping problem and clean out any sludge if there is any in my transmission?
