Maintenance and Specifications TRANSMISSION FLUID Checking automatic transmission fluid The automatic transmission does not have a transmission fluid dipstick. Refer to your Scheduled Maintenance Guide for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid. However, the fluid level should be checked if the transmission is not working properly, (i.e., if the transmission slips or shifts slowly) or if you notice some sign of fluid leakage. Transmission fluid should be checked and, if required, fluid should be added by a qualified technician. Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components. CHECKING AND ADDING TRANSFER CASE FLUID (IF EQUIPPED) 1. Clean the filler plug. 2. Remove the filler plug and inspect the fluid level. 258
