Remove the valve body. Before lifting the vehicle: Place the transmission gear selector in Neutral. Leave the driver door unlatched. A step further in the procedure may require it. Refer to the Electronic Service Manual (ESM), section TM – Transaxle & Transmission, for valve body removal. NOTE: o The number ‘7’ is on the head of all bolts that need to be removed for valve body removal. Do not remove any bolt that does not have the number ‘7’. o Due to multiple model vehicles, pictures throughout the service procedure are examples and may not exactly match your vehicle. CAUTION: Never allow any chemicals or fluids other than NS-3 CVT fluid or equivalent to enter the CVT assembly. Never allow any foreign debris, dust, dirt, etc. to enter the CVT assembly. NOTE: For additional information, see video # 546: “CVT Chain Inspection”. This video is located under the TECH TRAINING GARAGE VIDEOS tab in Virtual Academy. 7/24 ITB15-012g 2. Secure the right front tire with a suitable strap. This will assist in making the chain turn. 3. Mark the left front tire with a suitable marking. This will assure all 360° of the chain is inspected. Figure 5 4. Using borescope J-51951 with mirror attachment, visually inspect the side of the chain that comes in contact with the pulley: a. First inspect the entirety (360°) of the driver side of the chain that comes in contact with the pulley (see page 10, Figure 9 and 10, and page 12, Figure 13). b. If the inspection result is OK on all 360°, inspect all 360° of the passenger side of the chain. NOTE: Reference the pictures on page 13-15 for comparison. Insert the camera lens behind the pulley between the guide rail and pulley where shown in Figure 6 (also see page 9-10, Figure 7-10). Insert the lens approximately 8-9 inches, and then view the side of the chain that contacts the pulley. Chain Pulley Guide rail ------ ------ Front Driver side Step 4a Step 4b Figure 6 8/24 ITB15-012g Figure 7 shows where to insert the camera lens on the driver side of the chain. Chain Pulley Guide rail Camera cable ------ ------ ------ Figure 7 Figure 8 shows where to insert the camera lens on the passenger side of the chain. Chain Pulley Guide rail Camera cable ------ ------ ------ Figure 8 9/24 ITB15-012g Figures 9 and 10 show the routing and location of the camera. NOTE: The CVT’s side cover was removed for easier viewing of camera location. The side cover is not to be removed at any time during this procedure. UP Camera lens positioned behind plastic guide Front of vehicle Camera cable Primary pulley: Camera cable routed past primary pulley Figure 9 For best picture, position camera lens 10 mm away from chain Figure 10 10/24 ITB15-012g 4c. Slowly and carefully turn the left front tire one full turn in the forward rotation to view all of the chain. Holding the borescope with one hand allows for turning the tire with the other hand (see Figure 11). CAUTION: If the tire is rotated in the rearward rotation, the camera lens may get caught between the chain and pulley. d. If the inspection result is OK on all 360° on both sides of the chain, skip to step 5 on the next page. Figure 11 If any evidence of chain slippage is found, go to step 4e, and then skip to step 6. Refer to Garage Video 546 if needed (see bottom of page 7). e. Once CVT replacement is determined as required, use borescope J-51951 to record a 15 second or less continuous video of the most severe evidence of chain slip and the VIN on the F.M.V.S.S. certification label (VIN label). See example in Figure 12. Example of VIN label location For best picture, the camera lens should be about 10 mm away from the object being recorded. Figure 12 NOTE: This required video must be attached to the Powertrain Call Center CVT Preauthorization Form (in ASIST) prior to calling for authorization. Failure to submit a continuous video will cause immediate denial of request for replacement. 11/24 ITB15-012g Before starting to record, make sure the camera handle’s AA batteries are fresh and the LCD monitor’s battery is charged. The whole video will show as backward, or reversed mirror image. This is okay. The required video must show clear evidence of chain slippage and be 15 seconds or less. 5. Flush the CVT cooler(s). IMPORTANT: A CVT Cooler flush is required after a valve body or CVT assembly replacement. Refer to bulletin ITB15-010 to perform CVT Cooler flush. 6. If the chain inspection result is OK, replace the valve body. There is no need for pictures or video showing “OK” chain surfaces. For valve body replacement, go to page 16, Control Valve (Valve Body) Installation. 7. If the chain inspection result is NG, replace the CVT assembly. Get authorization to replace the CVT assembly (see page 25). Make sure to perform step 4d on page 11. Refer to the ESM, section TM – Transaxle & Transmission / BASIC INSPECTION, for CVT assembly replacement. IMPORTANT: Perform "ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY". o Check for fluid leakage. o Install Write IP Characteristics to the TCM; see ITB13-055.
