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 Trans 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 Trans Fix is the only bottle you need to optimize transmission performance.
Shake well. One bottle treats 7 to 11 quarts of fluid. Use 1/2 bottle for 3 to 6.9 quart capacity. Add Trans Fix to transmission, do not overfill. 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 Trans 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 Trans Fix is an advanced formula that includes:
These additive packages stop slipping, rough shifting, seal fluid leaks and reduce noise. Bar’s Leaks Trans 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).
Trans 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.

This is a wonder drug for cars. My car runs better then when I first bought it. Thank you so much for this.
Easy to use product. Noticed smoother shifter after first day. Great for the price.
This product was very easy to use and nice for a vehicle was issues but you can’t afford to replace it.
The product is easy to use. I felt less slipping and smoother shifting, after using the product.
I like most that it really did help the slipping in my transmission. It completely did what it said it was going to do.
