If the transmission control module (TCM) is the brain of the transmission, valve body would be the heart. If something were to go wrong with the transmission valve body, certain features of the automatic … Read more

5 Benefits of a Limited Slip Differential (How it Works and Its Cons)

limited slip differential pros and cons

There are three types of differentials that a vehicle could have; open differentials, locking differentials, and limited slip differentials (LSD). The function of any differential is to transmit engine power to the wheels. This is how wheels can rotate at various speeds. While an open differential would still power any wheels that are losing traction, … Read more
