When I brought in my car for rear end service, AAMCO Transmissions said it would be cheaper to replace the rear end with a new $1,700 rear end. Then after they put it in, they say it's used and it has $800 damage, and they wanted to charge me $800 in repairs. I said no, put in the old rear end and I'll go somewhere else. So they fixed it, and they ate $1,000 of the cost. They completed their end, and fixed the rear end, but they never adjusted my emergency brakes. I took the car somewhere else to finish the repair. They were very polite and courteous, I was just floored that they would put in a part that wasn't 100% functioning and then ask me to pay for repairs. They were in a pickle; their supplier gave them a damaged part, but then to ask me to pay for the repair was ludicrous.
