Just to update. I can only replicate the chirp on the 3 - 4 shift and ONLY when the torque converter is unlocked while going into that shift. This requires a medium to hard acceleration and staying in the throttle consistent into that shift. Mild acceleration or even a slight lift going into the shift and the TC locks and I never hear the noise when it's locked. The 3 - 4 shift seems to be the hardest shift of all and I believe or guess that under the scenario of going into this shift upon firm acceleration and being unlocked the TC locks simultaneous with the shift and jacks the tranny or something. For whatever reason it seems like it may not be as bad as it was, could be just because I've been doing more highway lately. But I'm planning to document and discuss with the dealer on first oil change. Frankly the tranny has been performing really well otherwise. Occasionally it gets all confused for a second and clunks around but so did my 2011 F250. I don't expect big trannies like these to perform as slick as a cadillac but the chirp crap has to go.
