The dealership was fantastic through the whole process. The trans lost a gear in August of last year. Then it started getting a little low on coolant. They found it in cyl #2 in January.
Donāt forget that turbo engines definitely need their oil changed every 5000 miles. That turbo heats the oil up way more than a typical NA engine. It also cooks it once the hot engine is shut off.
We experienced this exact scenario when towing our 3800lbs camper. On accel from a stop, it feels like a vibration in the driveline. Dealer saw irregular shift patterns in the trans, so pulled and completely rebuilt it. Still having the same issue. I'm curious as to if there is a TSB for this...
Well, they pressure tested and replaced the EGR cooler, claiming that it was leaking. However, I continued to see the coolant level drop below the minimum. Finally, they used a boriscope to look into the cylinders and well, you know the rest.
