In this video, I outline the process of replacing the automatic transmission fluid and filter on a 2005 pontiac sunfire with a GM 4T40E 4 speed automatic transmission. This is a fairly simple job but be warned because it's extremely messy.
I am not responsible for any mishaps that may have occurred from following these procedures. I do this to help you, the car owner, and cannot assume responsibility for any problems. Please use this information to help yourself, good luck, and take care.
