If a Mazda MPV is leaking yellow fluid then it is possible that the fluid is brake fluid. It is best to take the car to a mechanic right away.
Coolant
yellow, brown, red????
The better question is what is leaking transmission fluid?
Probably your radiator fluid leaking out.
where is it leaking from?
That is the correct spelling of "leaking" (losing fluid or pressure).
fluid is a lubricant of transmission
transmission fluid
Transmission fluid.
That's automatic transmission fluid , or power steering fluid , so it would depend on where it is leaking from
If a transmission is leaking fluid, it is likely that a seal or gasket has failed. Replace the gaskets and seals and the leaking should stop.
