Steel Modules, Steel Plates, Friction Modules. Modern automatic transmission systems are complex, containing many parts that work together to transmit power from the engine to the tires. Within this system is the clutch, which is made up of several discs that are assembled in order to facilitate gear changes. Although often forgotten and ignored, the clutch has a very important function, as this device transfers power from the engine to the vehicle's transmission. 

It is common that with time and use, the clutches wear out. When a clutch begins to slip it is a sign that it is necessary to take measures in order to fix it. Unlike the manual transmission, automatic transmission clutches must be covered with fluid as a damaged clutch causes fluid contamination. Therefore the transmission clutch pack must be replaced and not only have its fluid changed. For this reason it is important to service the clutches and keep them in good condition without slipping. 

How much does it cost to change the clutch kit of an automatic transmission?

The cost to replace an automatic transmission clutch kit varies depending on several factors, such as the make and model of the vehicle, the type of clutch required, installation time and the replacement of other components such as the overhaul kit, clutch pack and transmission filter, which further affects the total cost. In general, the cost ranges from $280 to $850 USD. At Sun Transmissions we offer high quality clutch kits compatible with various makes and models, ensuring optimum performance and durability.

At Sun Transmissions we are experts in automatic transmission systems. We invite you to browse our online store and find the most suitable automatic transmission clutch packs for your car.
