Remanufactured K114 2WD CVT Transmission Assembly 30400-10031 for Toyota C-HR 2.0L 2017-2022 RAV4 2.0L 2018-2023 Gearbox with transmission torque converter

Question: Does the same OE part number cover K114 units with different internal component configurations?

Answer: It is possible for K114 units under one identical OE part number to have minor differences in internal parts. During its production cycle, the OEM carries out minor iterative improvements. While the housing and external label part number remain unchanged, updates may apply to valve‑body solenoids, clutch plate thickness and thrust washer specifications to fix early design flaws. Ordering solely based on the OE part number risks abnormal oil pressure and rough shifting after installation. We cross‑check the VIN, housing casting number and valve‑body version to select properly‑iterated internal components, ensuring full mechanical and electronic compatibility and valid warranty coverage for B‑end buyers.

Question: Which core components are mandatorily scrapped instead of being reconditioned and reused during remanufacturing?

Answer: Certain core components will be directly scrapped once failing inspection in K114 remanufacturing and will never be repaired for reassembly. Scrapped parts include input / output shafts with excessive wear, scored pressure cylinders, fatigued CVT belts, burnt clutch friction and steel plates, cracked housings and bearings with excessive clearances. Components are rejected when measurements exceed OEM tolerance limits, even if they look visually intact. Reusable parts go through multi‑level inspections including dimension measurement and penetration testing. Strict scrapping rules prevent slipping, abnormal noise and belt failure, distinguishing our remanufactured units from simple refurbished ones and securing product reliability for overseas B‑end clients.

Question: Are all oil seals, O‑rings and oil pan gaskets replaced with brand‑new OEM‑specification parts?

Answer: All oil seals, sealing rings and oil pan gaskets of our K114 remanufactured transmission are replaced with brand‑new OEM‑spec parts; used sealing components will not be reused. After long‑term exposure to high temperature and hydraulic pressure, old rubber seals tend to harden and develop micro‑cracks invisible to naked eyes, which easily lead to oil leakage after vehicle installation. We strictly adopt OEM material and dimension standards and reject low‑grade aftermarket seals. Complete seal replacement greatly reduces field return rates, protects wholesalers’ local market reputation and is also a prerequisite for activating the full‑unit warranty.
