New Second Generation 018CHA CVT180 Valve Body Hydraulic Control Module

This new second-generation improved 018CHA CVT180 valve body hydraulic control module matches Chery Tiggo, Arrizo models equipped with CVT180 continuously variable transmission, corresponding OE numbers 018CHA1502600 and 025CHA1506251.

Each valve body is fully assembled and subjected to dynamic hydraulic bench testing to verify pressure stability, solenoid response and internal tightness. It solves common CVT faults including shudder during acceleration, slipping, delayed power output, gearbox fault codes and pressure fluctuation caused by aging original valve body. Direct replacement without complicated modification.

1. Appearance inspection: Check aluminum housing for casting defects, deformation and surface damage.
2. Internal component assembly: Install solenoids, spool valves and sealing gaskets strictly according to OEM standards.
3. Oil channel cleaning: Remove residual impurities to prevent spool sticking.
4. Static pressure leakage test: Eliminate hidden oil leakage risks.
5. Dynamic bench load test: Simulate real driving conditions to test hydraulic pressure, response and working noise.

• Pre-shipment Dynamic Bench Hydraulic Test

All valve bodies complete full load testing before delivery to reduce hidden failure risks after installation.

• Second-Generation Optimized Structure

Improved spool and oil circuit design effectively alleviates typical CVT shudder and pressure instability problems of the original first-generation valve body.

• Complete Supporting Parts Supply

We supply matching CVT180 pressure belts, overhaul kits and solenoid valves, supporting mixed consolidated orders.

• Flexible Wholesale Policy

1 piece minimum trial order. Tiered discount for bulk orders. Neutral unbranded packaging supported. Negotiable warranty terms for long-term overseas wholesale partners.

1. Thoroughly clean the CVT gearbox oil pan, oil filter and internal oil passages before installing the valve body.
2. Replace the CVT transmission filter synchronously to avoid new impurities blocking the valve body oil channel.
3. Fill with specified Chery CVT dedicated fluid; ordinary ATF oil will cause serious internal component wear.
4. Complete CVT adaptive learning with professional diagnostic equipment after installation.
5. Carry out road test to confirm stable pressure, no shudder, no oil leakage and no fault codes.

Our company specializes in new and remanufactured transmission assemblies and hydraulic valve bodies for Chinese domestic passenger vehicles. We focus on Chery, Geely, BYD, Great Wall CVT and DCT gearbox spare parts.

We are equipped with professional transmission bench test equipment, stable stock of mainstream domestic CVT valve bodies. We supply auto parts wholesalers and transmission repair workshops in Southeast Asia, Middle East, Russia and other regions. We provide fast delivery and professional English technical after-sales support.

Q1: The 018CHA valve body has original first generation and upgraded second generation. They look similar externally but differ in internal oil channels and solenoid parameters. Can they be swapped directly?

A1: Direct interchange is not supported. Although the first-generation and second-generation 018CHA valve bodies share similar outer appearance, they differ greatly in internal oil passage layout, solenoid parameters and spool specifications. Random replacement will cause unstable hydraulic pressure, obvious shudder during acceleration and persistent CVT fault codes. Please provide vehicle VIN or original valve photos before ordering, we confirm the correct version to avoid heavy maintenance losses for local repair shops.

Q2: What is your inner buffer protection solution? Will continuous shaking and extrusion during long ocean shipping damage precise spools or cause slight deformation of the valve housing?

A2: We wrap each valve body with thick shockproof foam and place it in a dedicated molded foam compartment inside neutral cartons. The whole package effectively absorbs impact and vibration. Proper packaging largely avoids scratches on internal spools and housing deformation. However, severe violent logistics impact still carries risks. We record packing videos before shipment as evidence to handle disputes if any damage occurs.

Q3: How many sets of second-generation 018CHA valve bodies do you keep in regular stock? Can packing and shipment be finished within 3–7 working days after full payment?

A3: We maintain stable spot inventory of second-generation 018CHA valve bodies to satisfy regular wholesale orders. After receiving full payment, we generally complete inspection, packaging and delivery within 3–7 working days. During peak overseas auto parts seasons, we prioritize delivery for long-term cooperative clients to avoid stockout delays and guarantee your continuous supply for local transmission repair business.
