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 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.


Fill hose included for easier application in some vehicles. Shake well. Add Super Transmission Fix to transmission per dosage chart on package. Consult owner’s manual if needed for transmission dipstick/fill plug location. Do not overfill. Drive vehicle normally. Depending on the transmission problem, results will be immediate or noticeable within 250 miles or 3 days of driving. In transmissions with seriously damaged components, a second treatment may be required. In this case, it is suggested that the fluid and filter be changed before adding a second bottle.

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.

Really Super Transmission Fix

2007 Ford Escape Hybrid CVT with 150K miles. Changed fluid and added this product for normal maintenance. WOW! Trans stopped whining which seemed to be a normal noise since purchase. Shifting in and out of hybrid mode was much smoother and quieter. Fuel economy improved dramatically. There must have been internal slipping that was undetectable in this CVT. I'm highly impressed!

You made this single dad happy

Hello, I just wanted to write and tell you how thankful I am for your product! I have a 07' Pontiac Grand Prix and have been having issues with the transmission slipping for some time now. Unfortunately from online reviews I went with Lucas' transmission fix. That didn't do a thing! So yesterday I decided on your Super Transmission fix & noticed results INSTANTLY! I couldn't believe it! I just got back from dropping my son off at school and am still amazed how there's no slipping or lagging like before. Wish I would have went with your product a year ago! If you need any reviews or anything from me please let me know. I'm an actual customer who's very happy! Being a single dad raising my son full time, I was worried about paying for a new transmission. Now I can rest easy that this will hold me over for awhile until I can afford a new vehicle. So thank you again!!!
