What is a transfer case and how often should I change the fluid?

Do you know how your engine delivers equal distribution to all four of your axles? That is due to the drivetrain system which is housed inside the transfer case. Your drivetrain is a compilation of complex moving parts such as chains, belts, and gears. The transfer case helps to deliver the engine torque from the transmission to the output shafts that connect to the drive shafts that lead to the front and rear axles. We know, that was a lot of information, but here at Melloy Dodge, our Express Lane Technicians know that an informed customer means a responsible customer. The more you know about how all the moving parts work on your vehicle, the better we can all take care of it! 

One of the many things we can do when you bring your vehicle into our Express Lane is to identify and inform you that the fluid inside the transfer case could need to be changed. It is recommended that this fluid is changed every 30,000 miles, particularly for those who utilize their two and four-wheel drive, and that is because all of these moving parts within the transfer case need to be properly lubricated for optimal performance. The transfer case fluid helps to remove heat, keeping the gears cool and running efficiently. Over time, the transfer case fluid begins to build up carbon from cooling these fast-moving gears. 

When you bring your vehicle into the Express Lane for your semi-annual maintenance, located on the south side of the Melloy Dodge dealership, you can expect that we evaluate and efficiently go over our multi-point inspection. This multi-point inspection sheet will be handed to you at the end of your vehicle’s service. If you are interested in having the fluid changed in your vehicle’s transfer case, our professional technicians can assist with getting that scheduled!
