Hello! I have a 94 legacy wagon (non turbo) with around 211,100 miles on it. The automatic transmission is acting up. It shifted a little hard, followed by a spike, then fall in RPM. It rolls while in park, and there is ticking noise when the rpms go up around the 3 mark. jerks into gear from park, and ticked when i moved it on to level ground. Any idea what it could be? Currently unemployed, and dont have money to chase issues! Thanks in advance
