D & M Transmissions will not be held liable for any incidental, consequential or exemplary damages; including, but not limited to, towing fees, rental cars, and loss of work or down time. This warranty will be void if a problem is caused by an accident, plowing snow, or damage by mud or snow, overloading, misuse, abuse or unauthorized work done to the transmission.
