Mechanics who specialize in transmission installation, repair, and maintenance typically have attended a trade school to learn this skill. If not, they have put in long years of experience to learn the trade. Some may work within dealerships, while others own their own auto body repair shops.
Good skills to have in this business include the ability to work well with your hands, attention to detail, a knack for troubleshooting, and good time management skills. Most mechanics know how to install new and used transmissions and related parts, like gears, shifts, clutches, and filters. Most also perform oil changes, fix fluid leaks, and repair housing components.
Customers can bring their automatic or manual cars or trucks into a shop, outlining what the problem is, such as slipping gears or shuddering and jerking of the stick shift. The mechanic will then have a look under the vehicle's hood, assess the situation, then give an estimate of how much it will cost.
The customer can then decide if he or she wants to have the mechanic fix the problem or take it for a second opinion. Professionals who repair transmissions are part of a competitive business; you may find price matching here. This can work out in your favor if you find a reputable mechanic who can provide services pertaining to your automobile's transmission, motor, or engine. Visit a specialty mechanic if you need transmission work on, say, a classic car.
Repair shop technicians can tell you how long your automobile will be in the shop. This way, you can make other arrangements for transportation in the meantime. Automotive shops may also sell transmission parts, or will be able to order them for you. There are also kits and manuals for sale from automotive supply shops, either in store or online.
