My dad has a 2008 GMC Acadia and this thing has a non-serviceable transmission filter, in fact it does not even have a pan! Just a drain plug. I try to keep the intervals short since its easy to change but with no filter that is only going to do so much. Anyway I came across this online and thought it would be a good idea? B&M 80277 Universal Remote Transmission Filter Kit Does anyone have any experience with these things? Does anyone know if its compatible with any transmission or only certain kinds?
