I took my truck to a mechanic whom checked out my transmission and could not find a problem, I had already got a code from O'Reilley's auto parts. The mechanic put a reader on the truck for a more specific scan and cleared the code. He suspected that my catalytic converters may have been plugged, and his regular exhaust system mechanic was on vacation, so he drove it to these guys to have them checked. They called and said it was ready. I went to pick it up and was told they found nothing and the code had been cleared, it didn't need scanned for a 3rd time. I don't think they ever even looked at the converters or even scanned it. Just charged me $80.00 for nothing. They said my truck was out front. I found my truck parked right beside the road, unlocked with the keys in it, where the transmission guy had left it for them to check. Anyone could have just got in and drove away, I don't think they ever checked the catalytic converters or anything else. So all I got for my 80 bucks was an invitation for anyone walking by to steal my truck. Bunch of crooks. On top of that the guy was very rude and acted like it was a big bother for him to even wait on me and write up the ticket charging me 80 bucks for nothing. Never again, if you use them BEWARE !!!!!!!!!!!!!!! read more
