    Also make sure the engine is running up to snuff ! Some times you need to tune it up. Make sure all the filters and plugs are changed or have been. All the vacuum lines are in place and the vacuum reservoir is not rusted out. Once you check this stuff and it's OK. Take it to a good transmission place. They can tell you what may be wrong with it.
