We were sent to RK Trans by another shop because of a computer/transmission problem with our older model Toyota. Despite several failed attempts caused by faulty computers supplied by a car computer company that we had contacted, Robert stayed the course over several weeks until the job was completed successfully. The communications were excellent at all times, and Robert took the time to explain the issues clearly and answer all of our (many!) questions. We are very impressed by all aspects of RK Trans and will definitely use their services in the future.
