Lubegard 19610 Instant Shudder Fixx, 2 oz.

Works like a miracle if you can get a mechanic to put it in Lasts about 2 years.

Used this in an Audi A8 D3 with 6hp trans, as part of a trans fluid change. Converter judder almost completely resolved. Well worth a go if you’ve got a judder, although definitely suggest doing fluid as well.

Solved the shudder on my Range Rover but took about 2 weeks to to fully stop it i added to the old oil and has lasted about a few months so far when I change the atf I will add a new tube to keep my transmission running smooth

Bought this with some scepticism and had it added to the transmission of my high mileage Range Rover TDV8 ( 207360 miles ) which had developed a shudder ( a bit like driving over a cattle grid ) under certain conditions. Just adding this product, no other flushing or replacing oil, cured it immediately and now, with another 17740 miles added on the clock, the torque converter is still as smooth as it was when it was young. It has a hard life too, country living and towing a 3.5 tonne loaded trailer for a fair amount of mileage. Maybe I was lucky but having had a replacement torque converter fitted at around 100k miles this time Lube Gard saved me spending another £1700. Well worth a try for a tenner.

I’m amazed this stuff actually worked. I thought it was snake oil but it stopped my revs fluctuating at constant speed. I realise it’ll probably only be a temporary fix. Land Rover discovery 3, I used two tubes

Bought this for a Disco 3 with fluctuating revs. Pumped a small amount of transmission fluid out from the hose connecting to the oil cooler and inserted here. It had immediate results. No fluctuations. Very impressed.

Left it a few months before writing a review. Added it to my car as explained and then I read others reviews online explaining how after 1000 miles the gearbox fails. I’ve done a few thousand and it is faultless! My car never juddered before having a service inc gearbox, but after having new oil and filter it did. Thought it was worth a try and I’m pleased I did.

I have a w220 Mercedes s320 CDI that has suffered with the dreaded gearbox shudder and this little tube of lube just sorts it out every time.

Had quite a bad shudder on a Ford Smax 2019. One tube did the fix. I still can’t believed it worked. Amazing!!!

Tremblement sur Mondeo 190cv bva8 (8f35). J’ai mis le produit dans l’huile de boîte et directement problème réglé. Incroyablement efficace.

Usato sul cambio automatico di una land rover ha tolto le vibrazioni in modo quasi miracoloso.... ho effettuato due cicli a distanza di 2000km per rendere ancora più fluido il cambio Quando lo maneggiate dotatevi di opportune precauzioni per proteggere occhi e mani!!!!!!!!!!

Used in a 2005 Chevrolet Trailblazer with only 36K miles that developed a torque converter shudder problem. It was not severe, but it was noticeable between 1st/2nd/3rd gear shifting under load, especially around 45 mph. Added Lubegard Instant Shutter Fix, and within an hour of driving the shudder issue has been almost completely eliminated. I will be changing out the fluid and filter soon, but needed an immediate fix, and this did the trick. I am impressed with how fast it worked. Application was easy - just pour it down the transmission dipstick tube. Took literally 1 minute. Make sure you have a paper towel or two with you when you cut the tip off the pour tube on the squeeze bottle. The product is packaged with a little pressure and 2-3 drops may come out. Only cut the tip off as you'll want enough pour tube to get an inch or so into the dip stick tube, or use a small funnel.
