Every once in a while if I keep a steady throttle at about 1400-1600 rpm in third going about 45 or so my transmission will flare for just a half second a couple hundred rpm or so and then drop back down . I had the dealer replace the gov pressure solenoid and that did not help, and by the way that dosent get rid of the 1-2 shift hunt either. It dosent act up at any other speed does anybody have any ideas? Thanks in advance for the help.
