I am hoping someone can help me out here. My wife has a 93 Mazda Protege ATX. Now that the temperature is getting colder out, shifting her car into gear is very stiff. It was fine out when it was warm. Didn't notice a thing. It has 134,000 miles on it. She has had it a little over a year. Anyone have any ideas? It feels like the transmission fluid is very thick. I don't know a thing about transmissions and I am looking for some help before I take it somewhere to be looked at. Thanks everyone.
