Today I was cruising in the car and I came to a stop sign after about five minutes, the car felt like it went into neutral. I revved it a little and it came back in. Started for home and had to pull over because it was slipping so bad, shut it off to maybe let it cool. After a minute I started it up, put it in gear, and it felt good, went about a mile and did the same thing. Reverse was gone too. This car hasn't been on the road in ten years, but all of the shifts feel solid. Is it common for the filters to plug up and lose line pressure? Has anyone had a filter come apart or sludge up from sitting. This is a secondary project car, and I know that if the filter is plugged its probably from internals failing, but if I could get a summer around town out of it I would be pumped. Any thoughts?
