this is the story my car is losing water somewhere and i dont know where from, car is not overheating and there is a brown muck on the rad cap. what could this mean is it the head, the gasket, or losing it from somewhere else.
Check the tranny fluid ASAP if it's frothy/foamy/creamy then ur in the poo. Otherwise if it's a nice clean red fluid and ur engine oil isn't contaminated either then the leak is likely an external one which is the better leak to have.
a bit of brown muck isnt much. It happens and Ive done over 100,000 with it happening... So no stresses with that mate. Rough on idle can be a few things but I would highly doubt that its got anything to do with crap under ur radiator cap.
if your not leavin water anywhere it be leakin while under pressure really itsnt a bad thing just keep an eye on it. if ur really stressed about it get ur block and radiator crack tested

Your engine coolant & your tranny fluid are both cooled by the radiator. The radiator has two 'chambers' roughly speaking.. one for the coolant the other for the auto fluid. if there is a leak between these chambers coolant is allowed to flow into your transmission and vice-versa. Tranny's don't like coolant! .. on the bright side it could be as simple as a dodgy radiator cap BUT eliminate the more costly possibilities first.
