For those who are experiencing Acadia trans problems....Believe it our not, try this Try running Premium gas! I was having all kinds of shifting, slipping and chugging problems. Vehicle had a hard time maintaining a constant speed and the engine light came on. Tried Lucas trans fix, changed the fluid twice...nothing worked until by chance i filled up with premium gas. After i burned about a quarter tank, all the problems went away, and the engine light went off.
