I have an 06 Malibu with the MN5 tranny. It also has Dexron 6 in it. At 53,000miles does any one recommend getting the fluid exchanged? I have shops here that will do the flush or drop the pan filter and fluid. I just find it silly spending all the money on the fluid and when you just drop the pan and filter is doesn't take out the fluid in the torque converter? What do you guys think? Should I leave it till 100,000 miles or change it at 60,000 and maybe the price per quart of the fluid will go down? Thanks in advance.
