JLM Automatic Transmission Fluid ATF Stop Leak & Conditioner J07010 JLM LUBRICANTS

Designed to prevent slipping, leaks and wear, JLM’s Automatic Transmission Stop Leak & Conditioner provides smooth, quiet operation while conditioning the seals to extend transmission life.

Automatic Transmission Fluid (ATF) performs a number of critical roles. It acts like a hydraulic fluid to enable shifting, protecting gears and bearings from wear, managing heat and providing frictional properties to ensure smooth, consistent shifting. Over time, the fluid deteriorates, especially if the transmission gets extremely hot from dragging or dragging.

Heat causes transmission fluid to oxidize or break down. Fluids that break down create sludge that clogs narrow passages and interferes with shifting. Worn fluid may also not provide the proper frictional properties for your transmission. Eventually you will notice that your vehicle is shifting hard or erratically. Over time, the seals can also harden, causing them to crack and leak.

JLM’s Transmission Fluid Additive is designed to restore the properties of the fluid responsible for providing proper frictional properties, heat resistance and other benefits. In addition, it is also designed to soften and swell worn seals, supposedly to “fix” leaks.

These are the most common questions we get.

Do any of the JLM additives help the performance of the high pressure diesel fuel pump?

J02330 Rapid is perfect for pump and injectors!

Is it OK to use the JLM Extreme Clean and the DPF Cleaner together?

No, this will not have a positive effect. In fact it may cause an adverse effect. And also the risk of overdosing! Never combine fuel additives


Will JLM Bluboost dissolve existing crystal infestation or is it more like a preventative product?

JLM’s Bluboost additive cleans and prevents crystal formation in the AdBlue® dosing system. It also conditions the AdBlue® fluid for a longer time to ensure proper working of the AdBlue® and SCR system. This helps prevent performance loss and the often-subsequent expensive repairs. It also reduces foaming at low temperatures

Is the JLM Engine Oil Flush safe for use with wet belt engines?

Our JLM OIL FLUSH is safe to use with ‘wet belts’ (TBIO). This is mainly because we use non solvent and premium pack of oil cleaning additives.


Does the Petrol Emissions Reduction Treatment also clean the catalytic convertor?

The catalytic converter is not a filter, it functions by converting harmful emission gases into less harmful gases. The filter can become contaminated if for example there has been an oil leak, and when this happens the filter needs to be replaced. There is no additive or chemical that will remove physical contamination from a catalytic.
