The roar of your Mustang is impressive and leaves no one in doubt of its power, but it is not just the power that gets your car moving. The engine creates the energy, but your baby would not go far without a first-rate Mustang transmission to convert all that energy into movement. A transmission is a vital component that literally stops a vehicle in its tracks when it stops functioning. Whether you need to repair a Mustang you have owned for years or you want to create an incredible sense of accomplishment by building your own vehicle, you have to choose the right transmission and engine components. Some models offer incredible versatility with Mustang 6-speed transmissions. Other models feature simpler Mustang 4-speed transmissions, but that does not mean they skimp on power. Both automatic and manual transmissions are available among the large inventory on eBay, and both types offer safe and reliable performance. In most cases, the decision on which type of Mustang transmission to choose usually comes down to your personal driving style and your budget.
