Almost a week and $1000 later...
I got my car back. Main shaft bearings were messed up, had a new clutch installed, and I bought new tires. Anyway, I have a quick question. If a shop screws something up (like putting ATF in a manual transmission), but you don't have paperwork proving that (except what's in their computer system), is there an effective way to approach them & tell them the situation to maybe get them to pay for part of the damage?
