When the vehicle is "cold" the gear that normally comes at 25 mph engages at around 30@2000rpm then lurches as it engages. This does not happen when the vehicle has been running, just the first time I get over 30mph in the morning or at cold start.

Have you serviced the transmission lately? Could have been time several miles ago.

Some manufacturers do use a later shift strategy when the engine is cold to assist the engine warming up faster. Is this something that is notably different than in the past?
