Do I need to drain all the transmission fluid out before using the blie devil transmission fluid?

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.
