    After time, transmission seals tend to dry out & shrink and internal parts become worn. Rislone Super Transmission Fix contains a seal conditioner, extreme pressure & anti-wear agents, cleaning detergents and a performance additive booster to stop slipping, seal fluid leaks and reduce noise.

  • How much do I install?

    One bottle of Rislone Super Transmission Fix, 500mL. part number 34516, treats 7.5 to 11.5 liters of fluid. For larger systems use 1 bottle for every 9.5 liters. Use half a bottle for fluid capacity from 3.5 to 7.4 liters.

  • Will Rislone Super Transmission Fix work in all types of transmission fluid?

    Yes, Rislone Super Transmission Fix is this first transmission additive formulated to work in all types and colors of transmission fluid.

  • Will Rislone Super Transmission Fix work in any type of transmission?

    Yes, works and safe to use on regular automatic (step, overdrive transmission, 2WD, 4WD, AWD), CVT (continually variable transmission), DCT (dual clutch transmission), ECT (electronically controlled transmission), manual (stick shift transmission), transaxle (front / all-wheel drive).

  • How long does it take to start working?

    Rislone Super Transmission Fix starts working the minute you install and start driving the vehicle. You will start to notice results immediately or within 400 km or 3 days of driving.

  • If first application does not completely stop my problem, may I add another bottle?

    In transmissions with seriously damaged components a second treatment may be required. In this case, it is suggested that the transmission fluid and filter be changed before adding a second bottle of Super Transmission Fix.

  • If I install more than the required amount, will it work faster or better?

    No, we have formulated our product to work best at the suggested dosage amount.

The days of needing a specialized transmission stop leak formula are over. With modern chemical technology advancements, it’s now possible to have a transmission treatment that handles any type of transmission.

This type of product is not easy to engineer. It requires years of experience, and a ridiculous amount of lab time. It requires a deep understanding of transmission technology, common problems, and what root causes lie behind these problems.

We did the research. We put the time in. The result is Bar’s Leaks Super Transmission Fix, the only transmission treatment that handles just about any type of transmission, including:

  • Automatic
  • Manual
  • CVT (Continuously Variable Transmission)
  • DCT (Dual Clutch Transmission)

If you have a transmission that’s suffering from leaks, slipping, jerking, hard shifting, shudder or just plain poor shift feel, Bar’s Leaks Super Transmission Fix is the only bottle you need to optimize transmission performance.

Bar’s Leaks Super Transmission Fix is an advanced, synthetic-blend treatment for transmission fluid, seals, metal surfaces, bands and clutch plates. Global domestic/import formulation can be used in all automatics, manuals, CVTs (Continuously Variable Transmissions) and DCTs (Dual Clutch Transmissions).

Bar’s Leaks Super Transmission Fix is an advanced formula that includes:

  • Seal conditioners stop current leaks and prevent future instances by protecting and reconditioning seals
  • Extreme pressure/anti-wear agents provide better metal-to-metal friction properties to stop slipping, jerking, hard shifting, shutter/shudder, which improves shift feel and provides better driving comfort
  • Advanced cleaning detergents include dispersants and antioxidants to remove sludge and varnish from metal parts
  • Performance additive booster renews worn bands, controls fluid degradation caused by high temperatures, reduces noise, and prolongs the useful life of your transmission

These additive packages stop slipping, rough shifting, seal fluid leaks and reduce noise. Bar’s Leaks Super Transmission Fix renews worn fluid and restores older and high-mileage transmission performance. Very effective and safe to use on regular automatic (step, overdrive transmission, 2WD, 4WD, AWD), CVT (Continually Variable Transmission), DCT (Dual Clutch Transmission), ECT (Electronically Controlled Transmission), manual (stick shift), transaxle (front wheel drive/all-wheel drive).

Super Transmission Fix helps with small leaks (for example, if you need to add fluid 1x per month), medium leaks (if you need to add fluid 1x per week), slipping/hesitation, rough/hard shifting, noise/whining, transmission warning lights and other fluid-related problems.
