The bottle says to add to existing fluid. After further reading online, their website says you can add it to existing fluid because it is supposed to dissolve in the old fluid, meaning you don't need to add or take any old fluid out. This made me skeptical because I don not want to overfill my transmission. I already have a plan on siphoning 24fl oz out to add the fix fluid in, but I don't want to under-fill my transmission if it says it dissolves in the current fluid. So do I add it in without taking out any or suck out 24fl oz and then dump the fix fluid in? And how long could I run my car with low transmission fluid if it indeed does dissolve?
