## Questions & Answers

**Q: I’m needing a stop leak for a manual Subaru Impreza, will this work?**
A: Hi, Jennifer. Thank you for your question, and for considering Bar's Leaks to help with a transmission leak in your Subaru Impreza. We appreciate the opportunity to help you. The product you are asking about - Bar's Leaks Automatic Transmission Repair (part number 1400) was designed for use in automatic transmissions, so we would not recommend you use it in your Impreza. For a vehicle with a manual transmission, we recommend our Bar's Leaks Transmission Stop Leak Concentrate (part number 1420). This product was designed to work with all domestic and import vehicles, with either automatic or manual transmissions. For a manual transmission, you would use approximately 2 ounces of stop leak per 1 quart of transmission fluid capacity. Leaks usually stop in 200 miles or 3 days of driving, but if the leak continues, a second application or mechanical attention may be needed.

If we can be of any further assistance, please feel free to call our Technical Support Team at 1-800-345-6572. We are available to help you Monday through Friday, from 8 am to 5 pm, EST.

**Q: would this help the whine with a slight slip?**
A: Yes, this product will help with those issues. This formula reduces rough shifting and friction, while eliminating slip, controlling temperature, and repairing shudder, chatter and whining. And how exactly does it do this? It reduces friction enough to prevent wear. It also helps control the temperature, while at the same time allowing some friction to prevent the internal clutch material from slipping. Hundreds of thousands of bottles sold nationally.

One bottle of Bar’s Leaks Transmission Repair, 16.9 oz. part number 1400, treats 8 to 12 quarts of transmission fluid. On smaller systems from 4 to 7.9 quarts, only use half bottle, pouring equal amounts from each side. For larger systems use one bottle for every 10 quarts of capacity.

If you have any other technical questions, feel free to contact our Technical Service Professionals at 800-345-6572 or if you would prefer you can use the contact us page on our website.

**Q: Dose this work with Type F transmission fluid?**
A: 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.

If you have any other technical questions, feel free to contact our Technical Service Professionals at 800-345-6572 or if you would prefer you can use the contact us page on our website.

**Q: can i use in transmission without any problem?**
A: Thank you for your question, and for considering Bar's Leaks Automatic Transmission Repair to help with your automotive needs.

When used, it will help reduce rough shifting and friction, while eliminating slip, controlling temperature, and repairing chatter, shudder, and whining.
