Hey I need some help, I have a manual car (BRZ) and its rear wheel drive. While towing it with dualys (front wheels go on the dualys and dont touch the ground but the back wheels are on the ground) I left it in gear accidentally. After noticing this after a couple miles I put it in neutral and then it started rolling smoothly. While it was in gear rolling though Im pretty sure the wheels were spinning for a large part of the time. Now whenever I start the car or drive it the engine makes a loud thudding sound... What can this even be and how would I be able to fix it??? Please anyone help.
