New Process 136, 236, 246, 261 and 263 Transfer Case Saver This is a new aftermarket plate that is designed to fit into your rear transfer case half to reinforce the areas inside the case that are often damaged by the oil pump. Over time the oil pump can wear a hole right through your case causing your transfer case to leak and ultimately damaging the transfer case. This is an updated plate that protects all four possible danger areas and replaces the older spring clip that was originally used by the factory to only protect one area. We highly recommend using this plate for any of the above listed transfer cases. If you are opening your transfer case for any reason, you should be putting one of these plates in to protect yourself from major transfer case problems.
