Driving automatics in stop/start traffic
Please could you comment on this statement on the IAM website as I always assumed you should put an auto into neutral at a standstill to minimise wear.
'When stationary in traffic, even for many minutes, it is not necessary to move the gear lever into neutral because the torque converter absorbs the engine propulsion force but does not transmit it all to the gearbox as the engine revs are too low. No wear is taking place.
In fact, more wear will take place if the driver engages neutral and then engages a gear when he is able to move off.
When stationary, but in gear for any period, the hand brake should be applied and the foot kept clear of the accelerator'

Theoretical cobblers. Put it in neutral. As soon as a torque converter auto is a few years old you can feel the tug if you don't put it in neutral. Often a 'handbrake' will not hold a car against this torque.
