Hiya,, curious been searching for a maitanance schedule for the tranny fluid but it is nonexistant. Talked to 2 dealerships they r just left guessing.. called GM customer no-service they don't have a clue.. anyone here know when to flush the tranny I got 28,000 miles and the flui d is a brown color..... Never had a car that never listed a service interval for tranny fluid.

Also, since there is no interval given on fluid changes could that be a liability issue if the tranny goes out under warrenty? if you never change your fluid cause of no service interval listed and the dealer blames you for neglect for whatever reason. I see this as a possible issue.... Also how can brown tranny fluid be good circulating through your trannny? please help dazed and confused lol
