Capress six cylinder for exchange

Caprice 2010, 6-cylinder, mileage 380, can increase internally. 2013 car, Masha'Allah, clean engine, but there is an issue with the transmission: when shifting to first gear, it delays slightly before engaging, then shifts fine and works properly. I use it regularly. The AC is cold, Masha'Allah. It needs some consumable parts. The engine is clean; I change the oil every 3,000 km. The car is not for sale, it's for exchange with a suitable car. Thank you, and please no calls—contact via WhatsApp only.
