When driving and coming to a stop, moving again the car lags in changing gear, especially between gear 1 and 2. The engine revs up but the car does not move. I cannot take this to the dealer because it doesn’t happen all the time so it might be difficult to replicate the problem. Sometimes there is a little jerk when moving from a parked position.
First step for this is usually a basic transmission service. Replace fluid, filter etc.
