TRANSMISSION
FIX.
SMOOTHER SHIFTS.
Lucas Oil Transmission Fix is a specialist non-solvent transmission additive developed to help reduce slipping, hesitation and rough shifting in worn transmissions.
Formulated to support smooth engagement, condition worn seals and help maintain transmission fluid performance.
Address Common Transmission Performance Problems
Worn transmission components and deteriorating fluid performance can contribute to slipping, hesitation and difficult gear changes. Lucas Oil Transmission Fix is formulated to help address these symptoms while supporting ongoing maintenance.
Helps Reduce Slipping
Supports smoother engagement in worn, compatible transmissions.
Reduces Rough Shifting
Helps improve shifting feel and reduce hesitation and chatter.
Helps Address Seal Leaks
Contains seal conditioners designed to help reduce leaks associated with worn transmission seals.
Lower Operating Heat
Helps reduce friction and manage operating temperatures in hardworking transmissions.
Controls Foaming
Helps control transmission fluid foaming and maintain effective fluid action.
Preventative Care
Suitable for preventative maintenance in compatible transmissions.
Designed for Smoother Transmission Operation
Lucas Transmission Fix forms a tenacious lubricating film that helps worn transmission components engage more smoothly.
Its specialised formulation helps restore fluid performance while supporting smoother operation in compatible gear-based transmissions.
A Specialist Non-Solvent Additive
Lucas Oil Transmission Fix uses a solvent-free formulation designed to support lubrication and help restore transmission fluid performance.
Unlike a conventional transmission fluid replacement, this is an additive intended for use with existing compatible transmission fluid, following manufacturer guidance.
How to Use Transmission Fix
Follow your vehicle owner's manual and Lucas Oil product directions before adding the treatment.
Confirm Compatibility
Identify the transmission type and check that the product is suitable for the vehicle.
Add the Correct Amount
Add through the vehicle's designated transmission fluid filling point, using the proper procedure and dosage.
Allow Normal Operation
Follow the vehicle's prescribed fill and level-check procedure. Normal use allows the additive to mix with the fluid.
Lucas advises approximately 355ml for smaller transmissions and one 710ml bottle for typical larger applications. Larger or badly worn transmissions may require more. Always observe the correct fluid level and vehicle instructions. Do not overfill.
Transmission Compatibility
Confirm your gearbox type before purchasing. Transmission Fix is not suitable for every transmission system.
Suitable Applications
- Compatible conventional automatic transmissions.
- Selected light-duty manual transmissions.
- Cars, vans and suitable hardworking vehicles.
- Preventative maintenance where appropriate.
Not Suitable For
- CVT continuously variable transmissions.
- Dual-Clutch transmissions (DCT).
- DSG transmission systems.
- Associated CVT, DCT and DSG transmission fluids.
This additive cannot repair broken internal transmission parts or completely burnt-out bands and clutch packs. It is not a substitute for diagnosing serious mechanical transmission faults.
Supporting Your Daily Drive
From routine commuting to hardworking vehicles, transmission performance plays an important role in the driving experience.
Lucas Oil Transmission Fix is designed for compatible systems where improved shifting feel, lubrication and seal conditioning may be beneficial.
It can also be used as part of preventative maintenance, following vehicle and manufacturer guidance.
