Mike Menefee –
My 2005 Lexus LS430 has almost 180,000 miles on it and recently developed a problem with the transmission downshifting from 2nd to 1st gear too early when slowing. I assumed I needed a re-built transmission or something but had the problem diagnosed to be a faulty ECM that needed replacing. The cost to do this was quoted by my mechanic at $2,900, which included a new ECM from Lexus and all the reprogramming that was needed. I decided to get a second opinion and started looking on the internet, Lexus blogs, etc. to see what others had done about fixing this issue. In the process, I came across Richard way down in Puerto Rico. He claimed to have the ability to test all the different components of the ECM and repair/replace those that were failing…….ALL FOR $150!! I called him and got a good feel from him on the phone so I sent my unit down to him and he repaired it and sent it back right away. He was extremely quick with the repair and I got the part back in 2 days. The installation was easy and my car works just like before the problem. I am so happy that I found him and would encourage anyone to use his services if they develop a problem with their ECM.
