Took a look into my coolant resorvoir today and noticed there is a bunch of oil and sludge built up in it. Any idea what would be causing this and how quick should I get it fixed?
If you're using dexcool, it could just be dexcool sludge instead of oil.
Flush your coolant and see if that clears it up.
If you think your up the the task of flushing your own coolant, go ahead and do it. Its really not that hard.
Another possible problem is maybe the trans coolers side tank cracked and is leaking trans fluid in the coolant.
But I'd flush it out first and see whats going on.
