I read somewhere online that it could be that the transmission oil is low. There is transmission oil? I thought there was just engine oil. My question is, what can I do about this? I don't have money to take it to a shop to see what is wrong with it, so I need to find out my self and get an estimate of the cost. My car is a 1996 Ford Taurus, with low miles. We have maintained very well, and it is otherwise a very good car. Could somebody help? Please?
