I have had my town and country for about a year now and have enjoyed greatly, however recently it has developed a problem. from first to second and only then it feels like it shutters or shifts back and forth between first and second. the tps has been changed and I am changing the plugs and cables today. any ideas? from 2nd to 3rd and 3rd to overdrive all is fine. thanks for any info!
