When a fault occurs, the first step is to determine if it is of electrical, mechanical or hydraulic origin before attempting any repairs. For this reason, an understanding of the transmission assembly's operation and design as well as access to specialized test equipment are necessary. Consequently, problems with the transmission assembly cannot be diagnosed using this manual. Therefore, all vehicle owners having issues with their transmission systems should direct them to Dealer Service Department or Qualified Repair Facility for evaluation. Similarly though a faulty transmission assembly should not be removed without being examined by an informed technician with appropriate tools because troubleshooting has to be performed in vehicle installation of the drive train.
