Liqui Moly Trans­mis­sion Cleaner – 150ml

Liqui Moly Transmission Cleaner is a professional-grade solution designed to clean automatic and manual transmission systems from the inside out. Over time, gear oil can accumulate deposits, varnish, and sludge that reduce shifting performance, increase wear, and shorten the lifespan of your transmission. This innovative cleaner helps eliminate harmful residues and restores optimal operation — all without disassembling the transmission.

This highly effective fluid is added directly to the transmission oil before an oil change. It works by dissolving contaminants, improving lubrication, and freeing up sticky components like valves and solenoids. After just 10 minutes of engine operation with the cleaner in place, you simply drain the old oil and replace it with fresh transmission fluid. What you’re left with is a cleaner, smoother-operating gearbox and a noticeable improvement in shift quality.

Liqui Moly Transmission Cleaner is compatible with most automatic and manual transmissions. Its advanced formula is safe on seals, gaskets, and other sensitive internal components. It’s especially useful in older vehicles with sluggish shifting, or when prepping for a complete transmission fluid change.

Formulated in Germany with premium quality and decades of engineering expertise, this cleaner ensures that every part of your transmission system performs at its best. Regular use can extend the lifespan of your transmission and help prevent costly repairs.

Whether you’re a DIY car enthusiast or a professional mechanic, this product is an excellent addition to your maintenance routine. It’s easy to use, highly effective, and a smart investment for anyone serious about keeping their vehicle running smoothly.

What is Liqui Moly Transmission Cleaner?

Liqui Moly Transmission Cleaner is a high-performance cleaning agent developed specifically for use in both automatic and manual transmissions. It is added to the transmission fluid prior to a fluid change, where it circulates through the system during idle or light driving for about 10 minutes.

During this short but effective cleaning phase, the formula works to:

• Dissolve and suspend sludge, varnish, and metal debris

• Free sticky valves and solenoids

• Improve hydraulic functions and gear engagement

• Remove harmful residues that compromise performance

Once the cleaning cycle is complete, you simply drain the fluid and contaminants with it, leaving a much cleaner environment for your fresh transmission oil to perform optimally.

Why Use a Transmission Cleaner?

Just like your engine needs clean oil to run smoothly, your transmission requires a contaminant-free fluid to function properly. Over time, heat, pressure, and oxidation cause transmission fluid to degrade. Dirt and residue build up, causing sluggish gear changes, delayed response, or even transmission slips.

These early warning signs are often overlooked until damage is already done. By using Liqui Moly Transmission Cleaner during regular maintenance, you:

• Prevent expensive repairs by maintaining component cleanliness

• Restore smoother shifting in aging vehicles

• Ensure longer transmission life through preventive care

• Prepare the system for optimal performance with new fluid

How to Use Liqui Moly Transmission Cleaner

Using this product is simple and doesn’t require mechanical disassembly:

1. Add one can of Liqui Moly Transmission Cleaner to the warm transmission fluid (ideal operating temperature).

2. Run the engine for 10–15 minutes, shifting through all gears if possible. Avoid driving under load.

3. Drain the used fluid completely along with the cleaner and contaminants.

4. Refill with the manufacturer-recommended transmission fluid.

One can (300 ml) is sufficient for transmission systems with up to 6–9 liters of fluid capacity.

When Should You Use It?

• Before every transmission fluid change – especially if you haven’t changed fluid in years

• In older vehicles with noticeable shifting issues or delays

• After buying a used car, where service history may be unknown

• As a preventive step, to maintain smooth shifting and avoid long-term damage
