Brought my 2020 3500 duramax truck in to get a new transmission and diesel particulate filter. After he was done I paid 13000 dollars. I asked Andrew if he reprogrammed the computer which is standard procedure when replacing the transmission and he assured me that that doesn't need to be done. We'll I didnt even make it 2 miles down the road. Truck wouldn't go into gear or anything. Called Andrew and he pushed the truck back to his shop... not towed but pushed with another truck which ended up ruining my tail gate and it won't go down all the way. No big deal just bad business. So he looked at it at his shop and it ended up being the new diesel particulate filter clogged up from him not doing a reprogram on the computer which i told him that needed to be done. So he had to put a new DPF back on which took 2 weeks. He called me up said my truck is ready. Again I asked if he did a reprogram on the computer so the problem wouldnt happen again and he still refused to do a reprogram. Andrew told me to get my piece of junk off his property and he's not going to work on it anymore. After I paid him 13000.00dollars I now have a truck thats basically in the worst shape before I brought it to him. So instead of trying to drive it I had it towed to my house so it won't get anymore messed up then what it is. Then had it towed to a chevy dealership to get a assessment on what is going on with the truck. The dealership told me that the person who rebuilt the transmission rebuilt it wrong and it's going to need a new transmission and reprogram the computer which is going to cost 9200.00. Andrew has refused to honor the warranty and correct the problem or refund the 13000 that I paid him. I should have known better doing business with Andrew when I first saw his employees drinking Twisted Tea while on the job. This guy is bad news and has no business working on anybodys vehicle because he obviously doesn't know what he's dong so I strongly recommend not getting your vehicle worked on at this shop. Trust me it's not worth it.... bad customer service drinking on the job and won't honor his warranty..... read more
