Love my buick. At 65,000 miles tranny started shifting hard (rattle the dash) no rhyme or reason. Do it not do it. Turn the engine off for a minute and it goes back to normal. Hills seem to cause it to act up. Once in a while when you want to go it's like in nuetral for just a second then catches and goes. No faults recorded 3 dealers are scratching there heads.

Could be a shifting solenoid, throttle pressure or governor pressure problem. Have the throttle position sensor and vehicle speed sensor tested-if okay Have the tranny pressure tested-
