I would like to thank technical domain for service, in the beginning I was a little skeptical about this order because I needed this part for my nice Toyota Corolla in Poland but I was going there for vacation so I ordered. It is working great so far. As described,fast delivery, good price. Thank You!!!

It’s being a great satisfaction sending my ECM unit to Richard in Puerto Rico for repairs and reprogramming. I must say I came across this website quite late after I had damaged the stock transmission of my 2004 Toyota Rav4. It was only after the replacement transmission also started experiencing harsh shifting issues from 2nd to 3rd gears and sometimes no reverse and with a bang as if engine or transmission mounts were worn out.
The turn around time was very short despite shipping from Ghana 🇬🇭 to Puerto Rico. Communication with Richard was very smooth, answering questions and inquiries in a timely manner when asked. Even though I had to replace the solenoid pack due to prolonged use of the vehicle in its limp mode at the end of the day, I have saved myself so much money from buying another transmission just by sending my ECM to PR for repairs and reprogramming. I have observed that other issues not related to the transmission were also identified and fixed by Richard. Very good customer service.
I am very thankful to you for helping me put my beloved Rav back on the road as it shifts much better than it was before the repairs. I entreat other owners of these year models experiencing harsh transmission shifting issues to quickly ship out their ECM to Richard before the tranny gets damaged as it were in my case. You would be glad you did. I did enjoy great discounts too.
