The color of the fluid can tell you what fluid is leaking – and how much danger that could signify.Looks kinda red…If it looks red, or a deep sort of pink, then it’s probably transmission fluid. One of the problems here is that transmission fluid can actually appear as different colors. These color changes, in themselves, actually indicate a problem with the transmission.
