When travelling at high speeds [~60mph or above] and stopping relatively quickly -- like for a stoplight -- car will often -- but not always -- stall

have not had the problem when able to coast before stopping

dealer has replaced lots of things; problem persists

If there were debris in the transmission they had to clean out of the transmission they should have replaced the torque convertor because you cant clean those.

Wow - I have brought the car in at least 3 times in the past couple of months where they did nothing because they couldn't get the car to stall on their watch - I will definitely talk to them about this pronto- you are awesome - thanks!
