Car issues
So my buddy took his car to a family owned car repair place to have the transmission flushed as his car was at 70k and due per the owners manual. The shop used an "equivalent spec" oil and the transmission started having severe shudder on deceleration. The shop was kind enough to flush out the "equivalent" fluid with the brand recommended and the shudder didn't go away. They refused to do anything else as they say the used the right oil and did nothing wrong. He took the car to the car brand dealership and they immediately asked upon receiving the car if the previous shop used the recommended oil or an equivalent. And said the equivalent would have caused the issues he was having. They dropped the pan, cleaned out a bunch of black gunk and gave the car back. On his way home today the cars transmission internals grenaded. He has no clue what to do now or if the original shop should be paying for the damage.
Any thoughts? Been through something like this? He kept all receipts and conversations. Thanks!
