Had a slipping automatic gearbox in my 4x4 put two bottles in it with a fluid and filter change a voila gearbox is like brand new well chuffed with it but small tip warm the bottles up first as it’s quite thick in the bottle I stood my bottles in a bucket of hot water for 30 min prior to use Read full review...

Made my gearbox far worse.
My car had developed a leak of oil from its gearbox.Although a manual gearbox, this stuff claims to fix leaks in all types of gearbox. I used half a bottle as is recommended for "compact cars". Once this stuff was added the leak became MUCH worse almost immediately. I took the car for a drive in the hope of it starting to work better when it got circulating. But that never was the case. The leak became so bad that it was coating my car's underbody and suspension in oil (now stained red by the additive). Not only did it make my gearbox worse it ruined my block paved drive. When I purchased this stuff I suspected that it probably wouldn't work - but I never dreamed it could have such a catastrophic effect as this.Read full review...

Automatic transmission saviour
I add this to my automatic gearbox when I change the fluid every second service since I first had transmission problems. Every 24,000 miles. More frequently than recommended but not expensive.
It kept my first faulty gearbox running for another 100,000 miles.
I then had a 60,000 miles second hand gearbox fitted and continued with the same practice. That gearbox is still working as new 220,000 miles later - I am a private hire driver.
My latest car (2010 Volvo S80 D3) has just gone in for a 340,000 miles service and gearbox fluid change with this additive and I expect it to go on smooth as silk and trouble free for at least another 100,000 miles, hopefully more..Read full review...

snake oil?
Absolutely not have used this on two of my cars that had just started to slip and hard shift, on one I replaced fluid and filter at same time on the other just drained a small amount of old stuff out before adding stop slip to both. Results were almost imeadiatly
noticeable no slipping or hard shifts. still running one of them with another 20,000 miles so far. Now one thing if your box is in limp mode , has missing grinding gears don't bother used early on a slightly worn box it's fine, noticed most negative reviews seem to expect far to much, it's not miracle stuff just practical liquid engineering.Read full review...

Hasn't worked for me...
Despite reviews from people saying that this product had instantly sorted all of their auto box problems, it has done nothing for the slippage in my Borg-Warner 35 - in fact, I think it might actually be a little worse. "If it sounds too good to be true...", etc,. etc...Read full review...

Gearbox treatment
I was sceptical about using this in my Land Rover but it has transformed the way it drives and goes up and down the gears like a dream. I would definitely recommend this product and encourage people to use it regardless if your vehicle needs it or not it just makes the gear changes so much smoother plus it has added lubrication,cooling and also stops leaks.Read full review...

Lucas transmission fix
I`ve used Lucas several times & it works well ,
I once used it in Chrysler voyager 2004 & it still worked well , with less slippage & more smoother changes , but it did jam up the gear selector around six months later , due to the thickness of the liquid .
wasn`t to difficult to fix this & still worked well after .Read full review...

Does what is says on the bottle!! ??
I have no idea if this will work in my old gearbox. however I did research, and the general consensus was that It is a general good fix it all. I have yet to use it in my gearbox having changed the oil to see what transpires. I HAVE ANOTHER VEHICLE THAT HAD A WORN STEERING PROBLEM AND PUT A SMALL AMOUNT IN, AND IT HAS HELPED FOR SURE. It is so thick I had to microwave 150ml to warm it enough to flow!!!!Read full review...

Great product
I’m probably bias as I’ve used Lucas products & believe they truly are as good as they say & trusting a long standing brand.
Really dose the job
