Who are we?

M&D Auto Ltd. has many years’ worth of experience in the automotive industry. More than seven years ago the company started focusing exclusively on repairing automatic transmissions.

  • In 2001 M&D Auto has built and equipped its workshop with automatic transmission rebuilding area, a warehouse, and office places.

We work with the most recent automatic transmissions diagnostic tools which help us recognize any problem in the transmission for any vehicle producer. We invest heavily in this diagnostic equipment and software to ensure we are always on the cutting edge. As well as computer test, we offer our clients a Test drive diagnostic which helps us diagnose automatic transmissions issues rapidly and precisely while in real working conditions. Providing full diagnostics, we can investigate a transmission in depth allowing us to gain an inside view and detect faults electronically in no time so we can provide accurate and quick repairs.
