Default Tranny jerks around 75MPH
2007 H2 with 64k mi. I have been commuting between IL and MI (360mi). I was on 94 cruising around 75mph, all of a sudden tranny jerks! It almost feels like up or downshift, but it wasn't. This happened twice. What could be causing this? Does GM powertrain warranty 100k mi cover the transmission?
