2007 Impala ss. Transmission hesitation occurs when going around 45-60 mph. Car semi-engages shifting, but then backs out, giving a chugging sensation while driving in that speed range. Higher speeds above 60 produces an incredible screech/whine noise. Currently in shop for transmission diagnostics. At 74,000 miles clutch was replaced due to it being cracked in half. Gm has either mad poor transmission engineering, using shotty parts, or this transmission is overly underrated for the power of the engine.
