SI-eVT Transmission - Motor A gap, China Variant & 9 inertia ring bolts For SI-eVT Transmission ONLY: Replace the nine (9) flywheel to damper bolts (68382486AA) when replacing the SI-eVT per TechConnect procedure. North America RU vehicles built prior to Nov 28, 2019 had a 05192374AB level cooler. All subsequent Si-eVT versions have the 05192374AC level cooler requires new 68413378AA inlet hose and 68425381AA outlet hose to service Nov 28, 2019 and prior VINs. China RU vehicles built prior to June 11, 2019 had a 05192374AB level cooler. All 68405320AC have the 05192374AC level cooler requires new 68413378AA inlet hose and 68425381AA outlet hose. The service SI-eVT is shipped with a non-China wiring harness (68241331AC). China market replacement must replace wiring harness with 68368596AA. The China variant 68368596AA wiring harness has an interlock to the electrical charge door. Production SI-eVTs have used motor "A" stators with 0.6 mm and 0.8 mm air gap. The PIM software must match the air gap. Mopar will now ship 68490840A* service SI-eVTs with a 0.8 mm air gap ONLY. Dealers are required to provide a VIN to the Star Center so the DNA of the VIN can be set to the 0.8 mm air gap software. In China, read the SI-eVT model number on the transmission ID tag or imprinted on the case. - all 05062509A*, B* have a 0.6 mm gap so use 68405320AC - all 05062509CA and later (0.8 mm gap) use 68490848AA
