Well as I went to check the fluids to make sure they're in order, trans fluid was barely showing on the dipstick, oil was about 6 inches past the full line, and the coolant was dark brown. The overflow tank was like a brown sludge. I think previous owner saw drops of "oil" coming from the radiator and just kept adding oil.
Leaks coolant and trans fluid from the radiator. Probably what blew the trans.
How hard is it going to be to clear out the cooling system? And is now the time to run a seafoam treatment?
