JLM Automatic Transmission Flush


 / 500ml

  • Cleans and flushes automatic transmission system
  • Remove sludge, grime, varnish, wear deposits
  • Compatible with all AT fluids and CVT/DCT
  • Overall better AT performance & increased service life
  • No aggressively solvents

JLM Automatic Transmission Flush ensures removal of nearly all the old and dirty transmission fluid before replacing it by fresh high quality AT fluid. As a result, your transmission should run cooler and receive maximum protection against wear to clutches, gears and bearings.

It should also shift consistently and crisply since the new fluid will provide the correct frictional properties (old fluid loses its frictional properties over time). In fact, a transmission that shifts hard, hesitates or jerks is sometimes due to worn fluid.

Sludge and other contaminants can accumulate in the fluid due to extreme heat breaking down the AT fluid. These contaminants circulate throughout the transmission before lodging in the filter. Before the filter can safely capture the contaminants, however, they can lodge in the narrow fluid passages inside the valve body, leading to poor shift quality.

Performing a flush with JLM’s Automatic Transmission Flush additive will help clean the transmission and more effectively remove accumulated sludge and other contaminants.

Product information


Compatible with all automatic transmission fluids including CVT and DCT.


For professional use with an ATF flushing machine only. 

  1. Ensure the engine and transmission system are at operating temperature before starting the flushing procedure.
  2. Connect the automatic transmission flushing machine.
  3. Add the contents of one bottle (500ml) into automatic transmission flushing machine and start the flushing procedure.
  4. Let the engine run for 10-15 minutes while shifting through all gears to circulate flush and clean the AT.
  5. Flush out the old ATF together with the flushing fluid and refill the automatic transmission with new ATF.
  6. Use recommended ATF only when refilling.
  7. Always follow the manufacturer’s instructions when draining, flushing and refilling the automatic transmission fluid.

Important: Always check that the ATF level is correct after completing the procedure and ensure the AT fluid level never exceeds the maximum oil level in the automatic transmission system during operation.

Dosage: One bottle (500ml) treats 8 – 12 liters of ATF. Recommended for use at 5% by volume.

These are the most common questions we get from a potential distributor.

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 extreme 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 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.
