XADO EX120 Automatic Transmission Fix ATF Additive — Reduces Slipping & Shudder, Restores Metal Surfaces (Red)

XADO EX120 Automatic Transmission Fix is an ATF additive and protectant designed to rebuild metal surfaces inside automatic and CVT gearboxes, reduce slipping and shudder, and extend transmission service life.

This concentrated treatment combines XADO's revitalizant chemistry with friction modifiers to repair microscopic wear, smooth contact surfaces and help stabilize shifting behavior across a wide range of automatic transmission types. It is formulated for use in conventional automatic transmissions, CVTs, Tiptronic, Manumatic and semi-automatic gearboxes. Use as a preventative top-up during routine service or as a targeted repair aid when symptoms like slipping, shudder or increased noise appear.

How does XADO EX120 stop transmission shudder and slipping?

The formula deposits a thin, wear-resistant layer on worn metal surfaces, evening out contact areas and reducing the stick-slip behavior that causes shudder. Friction modifiers in the additive optimize clutch engagement characteristics to reduce slipping without changing fluid viscosity significantly.

• Creates a restorative metal-ceramic layer on friction surfaces
• Smooths clutch engagement with anti-friction modifiers
• Reduces vibration and noisy gear engagement

Can I use this treatment in CVT and other gearboxes?

Yes — XADO EX120 is formulated to be universal across automatic transmission families, including CVT, Tiptronic, Manumatic and semi-automatic types. It is compatible with most ATF specifications, but always confirm compatibility with your vehicle manufacturer before adding any additive.

• Suitable for CVT and conventional automatics
• Works with clutch-pack and band-type transmissions
• Designed to be mixed into existing ATF during service

What improvements should I expect after treatment?

After application and a period of normal driving, you can expect smoother shifts, reduced noise and fewer occurrences of slippage or hesitation. Improvements depend on the transmission's wear level; lightly worn gearboxes often respond faster than heavily damaged units.

• Smoother, more consistent gear engagement
• Lower noise, vibration and harshness during shifts
• Extended component life through reduced metal-to-metal wear

How do I add XADO EX120 to my transmission and how often?

Pour the recommended dose directly into the transmission fluid fill or dipstick tube during routine service or fluid top-up. Follow the manufacturer's dosing instructions for your gearbox capacity; a single treatment is typical, with repeat applications only as needed based on symptoms or service intervals.

• Add through the transmission fill/dipstick tube with engine at specified operating conditions
• Use the dose matched to your transmission fluid volume
• Retreatment can be applied if symptoms return or per maintenance schedule

Who is this for? XADO EX120 is for car owners and professional technicians who want a preventative or corrective transmission additive that targets wear, sticking and slipping without replacing fluid immediately. It's useful for vehicles showing early signs of transmission shudder, noise or inconsistent shifts, for high-mileage transmissions needing extra protection, and for workshops offering service treatments that extend gearbox reliability. Always check vehicle manufacturer guidance and service intervals before use, and combine treatment with regular fluid checks and proper mechanical diagnosis when necessary.
