    My Lexus was downshifting very hard. I sent the ECU in and had it back in about a week and a half. My car runs great now and shifts so smoothly. These guys were easy to work with and responded to communication quickly.

    Slow but worth the wait

    I need it this repair immediately. They promised they would have it very soon. I even sent and pay for return postage because I was moving. They actually sent it back late well beyond their promise 5 days. It cost me hundreds of dollars in fee. I was pissed. But they did a great job and repairing my computer unit. I wish I would have known of them earlier. I already bought a new transmission that I didn't need. My ECU unit came back and my car is running perfectly. I'm very happy with the results. I highly recommend these people. Everyone should know about them. I was going to buy a new unit and it cost me over $1,000. They repaired my unit for $150. My car is running great for now. I hope in the long term it will continue to run.

    They rebuilt the ECM for my 2006 Lexus 430. It had the hard shift issue when going into first gear as you were slowing down. They called after they fixed it and said it was the transmission control unit in the ECM. It works perfectly now, shifting like butter. They were very prompt, only took a couple days after they got it and they shipped it back promptly. I would highly recommend if you need this service.
