Wynns 1831018 HPLS Transmission Treatment - 125 ml

Smooth gear shifting

Great product. Used it on few of my cars before and it always smooth out gears changing. Had a whining noise on one of previous cars and its quiet it down. Defenitely worth to add for easy gearbox improvement, especialy on some older boxes.Read full review

Made no difference

Can’t rate this stuff as quite simply it made no difference adding it to my Land Rover Discovery rear diff. Probably a tall order expecting it to cure or at least reduce a leak but absolutely no difference so a waste of money in my case.Read full review

It really works.

Near side driveshaft oil seal was worn on the gearbox of my car, this was replaced but the garage said that there was a leak coming from the casing somewhere. They said to find out where it was they would need to take out the gearbox which would cost hundreds of pounds to do. I had heard that you could buy a stop leak fluid so thought I'd try it....well I'm pleased to say it worked. Would defiantly recommend this product.Read full review
