I've just had my mech unit replace under stat warranty. I bought the car second hand (1 day out of factory warranty) and it was jerky takeoff, jerky reverse (with NO throttle!) and clunking when rolling away from stationary and no throttle. Happened the first night I got it, only when warmed up.

Just wondering, once they've replaced it, does it mean it won't happen again? or is it a wear and tear (thermal stress etc)? I wouldn't want to pay for a mech unit 4 year down the track cos it would have been $4500!
