## Questions & Answers

**Q: Do I need to drain all the transmission fluid out before using the blie devil transmission fluid?**
A: No you do not.  This is a good product that works on small transmission fluid leaks.  Unfortunately my vehicle had a leak that was too large and whilst this helped quite noticeably, it was not a complete fix in my case.  It definitely bought me more time before having to pay for an expensive repair.

**Q: Can I use on power steering pump**
A: unknowing for sure , it might if you use a.f.t in power steering pump

**Q: The directions say pour bottle in to Transmission, but then says "one ounce treats one quart of fluid".  So do I need 5 oz. or the entire bottle?**
A: One ounce per quart of transmission fluid

**Q: Could it damage the transmission or other car parts?**
A: Sorry can't answer that but it worked in a 56 year old transmission.
