- but it won't coast as far due to "engine braking". So you can choose - if you WANT engine braking, like when coming down a mountain or to a red light you didn't anticipate soon enough, then leave it in gear to slow down faster. But if you want to coast farther, putting it in neutral should do that.

One strange thing I found out though - - - in my fiance's '97 Buick Riviera, it seems to coast better in gear - ????? - almost the like the torque converter "disconnects" when the throttle is closed at speed. If I pop it into neutral, it seems to start slowing down faster. Strangest thing - I can't figure out what the heck's going on with that. ????
