One of the number one failures of modern transmission comes from torque report problems, and most often than others, from the engine not knowing it should be at a certain load. When I get a vehicle in for a tune to fix flair shifts and try to save the trans, the first thing I do is check the maf. Many times if you catch it as soon as you notice the flair or slip, it can fix the problem and report the proper torque to the trans to apply the proper shift and pre-fill/exit pressures.
