The guy said they did free diagnostics but the sign on the board behind him on the wall said $89 for diagnostics. Then $159 later to clean the transmission because the guy said it was dirty and "99% of the time" the guy said "cleaning it fixes the problem" then he called said I needed to get a new part and it would cost $600 so free was $750! Then when I took it for a second opinion at a friends shop he said the transmission was NEVER cleaned by amco like said and what we paid them for!! I was taken advantage of!!
