Classification: Reference: AT13-011d Date: NTB13-095d November 15, 2016 2007-2010 SENTRA; REDUCED PERFORMANCE DUE TO CVT FLUID TEMPERATURE PROTECTION LOGIC This bulletin has been amended to remove 2011 and 2012 model years. Please discard all previous versions of this bulletin. APPLIED VEHICLE: APPLIED ENGINE: 2007-2010 Sentra (B16) MR20 IF YOU CONFIRM: The vehicle speed is, or was, reduced by the CVT fail-safe (reduced vehicle speed) after continuous operation under all the following conditions are met: High RPM and/or high speed driving (4000 RPM or more, and/or 65 MPH or more for 1.0 – 1.5 hrs or more) Driving in ambient temperature of 96 degrees or higher Climbing steep or extended hills for 6 miles or more Whine or rattle type noise occurring during reduced engine performance (vehicle speed decrease) NOTE: Before applying this bulletin if the vehicle has any DTCs, they should be checked and repaired first. ACTION 1. Perform a self-diagnosis with CONSULT-III plus (C-III plus). If DTCs other than P0840, P0845, P0710, are present, refer to the appropriate section of the Electronic Service Manual (ESM) and diagnose the DTCs first before proceeding to step 2 of ACTION. 2. Check the number of counts of "CVT-A” and “CVT-B" with C-III plus. Refer to the Flow Chart on page 2 and the Service Procedure starting on page 3 to confirm if this bulletin applies. IMPORTANT: The purpose of “ACTION” (above) is to give you a quick idea of the work you will be performing. You MUST closely follow the entire Service Procedure as it contains information that is essential to successfully completing the repair. Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle. 1/10 Flow Chart Important Before applying this bulletin: Confirm that the CVT fluid has not been overfilled, and that it contains the proper CVT fluid. Confirm that the coolant concentration is not greater than 50%. Use of incorrect fluid, overfilling the CVT fluid, or coolant concentrations greater than 50% can cause the symptoms in the IF YOU CONFIRM section on page 1. Refer to NTB12-057 to resolve these conditions first if they should occur. NOTE: Refer to the ESM for the correct CVT fluid and coolant type for the model and year vehicle that is being worked on. Check the CVT-A and CVT-B counts with CIII plus. Yes Is the CVT-A count greater than 1? No Is the CVT-A count 24 or more? No Refer to bulletin NTB12-057 for related service information. Yes And/or Are 2 or more of the following DTCs stored? P0840 P0845 P0710 Replace only the Control Valve assembly, and then install the External CVT Fluid Cooler kit. Go to page 5. Pre-authorization is required before CVT replacement. Print screen showing CVTA; CVT-B counts for Powertrain Cal Center approval. Replace the CVT assembly, and then install the External CVT Fluid Cooler kit. Go to page 5. NOTE: If the CVT-A count is not greater than 1 and similar symptoms to those in IF YOU CONFIRM and/or a single DTC is present, refer to the ESM and NTB12-057 for further diagnosis. Refer to the ESM section TM – Transaxle & Transmission for removal and installation information for the Control Valve or CVT assemblies. 2/10 NTB13-095d SERVICE PROCEDURE Check CVT-A and CVT-B count with C-III plus 1. Open C-III plus and select Diagnosis (All Systems). Select Figure 1 2. Select TRANSMISSION. Step 2 Figure 2 3/10 NTB13-095d 3. In Data Monitor select TRANSMISSION and then select CVT-A and CVT-B. Select TRANSMISSION Select CVT-A and CVT-B 4. Select START. Step 4 Figure 3 Confirm VIN is present 5. Check both CVT-A and CVT-B counts and refer to the Flow Chart on page 2 to confirm if this bulletin applies. NOTE: If the CVT-A count is not greater than 1 and similar symptoms to those in IF YOU CONFIRM and/or a DTC are present, refer to the ESM and NTB12-057 for further diagnosis. CVT-A and CVT-B counts Figure 4 6. If it is confirmed that this bulletin applies, install the SERVICE KIT-COOLER-ASSY listed in the Parts Information. And If the CVT count is 24 or greater and/or two or more of the following DTCs are stored replace the CVT assembly. P0840 P0845 P0710 Or If the CVT count is less than 24, replace the Control Valve Assembly. IMPORTANT: Pre-authorization is required before CVT replacement. Print screen showing CVT-A; CVT-B counts for Powertrain Call Center approval. Refer to the Installation Instructions beginning on the next page to install the SERVICE KIT-COOLER-ASSY. Refer to the ESM section TM – Transaxle & Transmission for removal and installation information for the Control Valve or CVT assemblies. 4/10 NTB13-095d INSTALLATION INSTRUCTIONS 1. Place the vehicle on a lift and raise it as needed to perform the following procedure. Attach with 3 bolts 2. Install the “COOLER ASSY – AUTO TRANS. OIL” to the pre-existing weld nuts on the front of the radiator support with bolts from kit. Torque bolts to 7N•m (0.71 kg-m, 62 in-lb). NOTE: Figure 5 is shown looking from the bottom of the vehicle upward, at the lower front radiator/condenser support. COOLER ASSY – AUTO TRANS. OIL Figure 5 Route hoses past radiator into engine compartment NOTE: Figure 14 on page 8 shows an overview of the external CVT cooler and hose routing. 3. Route both hoses through the radiator support and into engine compartment. Figure 6 Remove Air Inlet 4. Remove the Air Inlet to gain access to the CVT Fluid Cooler. Figure 7 5/10 NTB13-095d Detach the harness and the battery J-bolt from the TCM Unbolt the TCM bracket and place the bracket out of the way Figure 8 5. Detach the Engine Room harness and the battery J-bolt from the TCM bracket. TCM moved out of the way and bracket removed 6. Unbolt the TCM bracket and place it out of the way. WARNING: Never remove the radiator cap when the engine is hot. Serious burns may occur from high-pressure engine coolant escaping from the radiator. 7. Relieve any residual cooling system pressure. Figure 9 a. Wrap a thick cloth around the radiator cap. Slowly turn it a quarter of a turn to release the pressure. Clamp both coolant hoses to CVT fluid cooler b. Then turn it all the way. 8. Clamp both of the coolant hoses attached to the CVT Fluid Cooler to prevent coolant loss. CVT Fluid Cooler Figure 10 6/10 NTB13-095d 9. Remove both of the CVT Fluid Cooler coolant hose (Water Hose B and Water Hose C) spring clamps and then remove both of the hoses from the CVT Fluid Cooler. NOTE: These spring clamps will be saved for reassembly. CVT Fluid Cooler with coolant hoses removed Figure 11 Do not disturb oil filter 10. Loosen the CVT Fluid Cooler mounting bolts (4 bolts) and remove the CVT Fluid Cooler. 11. Clean any debris from the CVT Fluid Cooler mounting surface with brake cleaner and a lint free cloth.
