Re: 97 mountaineer shifting problem
I'd keep things simple and cost effective as possible. First off, change the transmission fluid and filter. Also, if a tune up hasn't been done in the last 30K, it's worthwhile to get new plugs, timing checked and spark plug wires installed if they're still original.
