Investigation has identified a likely source of the seepage to be the sealant used on the CVT’s oil pump chain cover. The repair involves removal, a thorough cleaning and inspection of the sealing surfaces followed by re-sealing the cover. PART INFORMATION: Description THREE BOND 1215 RING SEAL Part Number SOA868V9600 31377AA510 SERVICE PROCEDURE / INFORMATION: As a first step, during inspection of the customer’s concern, confirm the fluid found to be seeping is CVT fluid (CVTF) and not engine oil. The photos below are examples of where CVTF seepage may be evident. Continued...

Page 1 • Once the inspection has confirmed the seepage is CVTF, remove the CVT assembly following the procedure outlined in the applicable Service Manual. • Remove the torque converter from the CVT and inspect the area of the oil pump chain cover as indicated in the photo below for any accumulation of CVTF and road dirt which may also have collected in the area. NOTE: A small amount of fresh CVT fluid may appear near the 6:00 position of the seal area during removal of the torque converter (GREEN circle).

Bulletin Number: 16-103-16R; Revised 04/20/17 Page 2 • Remove the 7- 12mm hex bolts securing the oil pump chain cover. • Using a prying tool and in the proper order as shown in RED below, CAREFULLY pry (GREEN arrows) the cover loose from the housing. Pry ONLY on the specific areas or “tabs” of the pump cover indicated by the BLUE arrows. When the cover starts to come loose, continue to pry ONLY on the tabs and not the machined sealing surface of the cover. • CAREFULLY remove all residual sealant completely from the cover and mating surface of the housing. DO NOT use any abrasive or gasket removal / cleaning discs. Use the adhesive side of a piece of duct tape (or equivalent) to pick up any loose pieces of sealant material which may be found in the cavity around the stator support. DO NOT use compressed air. • Take note of how the sealant on the removed cover forms an additional “seal” when it becomes displaced into the chamfer around the inside edge of the case’s machined surface at assembly. Continued... Bulletin Number: 16-103-16R; Revised 04/20/17 Page 3 • Inspect both of the machined sealing surfaces closely for irregularities. If necessary, replace following the applicable Service Manual procedures. • IMPORTANT: Before reassembly, always replace the ONE TIME USE plastic sealing ring on the center support and thoroughly lubricate it with CVT fluid. • Once both surfaces and the area surrounding the cover are completely clean and dry, CAREFULLY apply the new sealant bead to the cover along the edge of the chamfer as shown below. Continued... Bulletin Number: 16-103-16R; Revised 04/20/17 Page 4 DO NOT apply sealer around the arrowed hole. NOTE: As shown above, a properly applied, small bead of sealant will fill in the chamfered portion after the cover is installed. Do not use an excessive amount of sealant. • There are 2 different length bolts for the pump cover. Make sure the proper length bolts (A and B) are in their respective holes as shown below. Torque to 24 Nm (17.7 ft. lbs). • Reinstall the torque converter and the CVT assembly in reverse order of removal following the service procedure in the applicable Service Manual. • Road test to confirm the repair and proper vehicle operation.
