I used transmission additive #1400 in a 1979 F150 4wd. It was not downshifting when I stopped and hesitating on up shift when cold. 1400 and a fluid change cleared it up perfectly. I highly recommend Bar's Leaks Transmission Repair for any auto transmission before you have it rebuilt for $3000. - R. G. - Santa Clarita, CA
- How does Bar’s Leaks Transmission Repair work?
After time, transmission seals tend to dry out and shrink and internal parts become worn. Bar’s Leaks Transmission Repair reduces rough shifting and friction, while eliminating slip, controlling temperature, and repairing shudder, chatter and whining. Premium high mileage formula restores transmission performance.
- Will Bar’s Leaks Transmission Repair work in all types of transmission fluid?
Yes, Bar’s Leaks Transmission Repair is formulated to work in all types of transmission fluid. Use in regular automatic transmissions. Do not use in CVT transmissions.
- How much do I install?
One bottle of Bar’s Leaks Transmission Repair, 16 oz. part number 1400, treats 8 to 12 quarts of transmission fluid.
- 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 and a second application of Transmission Repair be added.
- 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.
- How long does it take to start working?
Bar’s Leaks Transmission Repair starts working the minute you install and start driving the vehicle. You will usually see results in about 100 miles or two (2) days of driving.
- Can I add to my existing transmission fluid?
Yes, follow these steps:
1. Remove transmission dipstick and check fluid level. For most vehicles this is usually done while the engine is running and the transmission is in Park. Tip: The transmission dipstick is usually located near the engine of dipstick but further back into the engine compartment. Some vehicles do not have a normal dipstick. For those, the product has to be added to the transmission through a fill plug. Consult owner’s manual for location.
2. If fluid is low, pour entire contents of the two chamber bottle into the dipstick tube. Do NOT overfill.
Tip: If necessary, to prevent overfill, drain some fluid from transmission.
3. Check fluid level again. Top off with manufacturer’s recommended transmission fluids as needed.
4. Replace dipstick and drive 10 to 15 minutes to circulate fluid.

“I drive a 1998 Ford Taurus SE. It has 136,000 miles. A few months back, I started to experience severe transmission problems. The tranny was slipping, the gears were laggy when shifting, and shifting back down through speeds was rough. I expected the worst for my car as I am in high school and cant exactly afford a new transmission. I had already tried draining the trans. oil and replacing it, with the same problems. I was walking through AutoZone one day and noticed "Bar's Automatic Transmission Repair" on the shelf. I thought it was my best chance if any, even though I was very skeptical. After having the trans. oil drained again, and adding a bottle of Bar's, improvement was quickly and obviously noticed right off. All trans. failure signs were gone within 100 miles. I've driven the car over 3,000 miles without a single transmission problem. Truly amazing, I dont know how you do it, but keep it up!”
