Brilliance H330 Transmission Cushion (MT) – Part No.: 4084859

Let’s keep it simple—this isn’t just a “rubber pad” under your Brilliance H330’s manual transmission (MT). It’s the key shock-absorbing and load-bearing component for the manual gearbox: a durable, precision-molded part made of rubber-metal composite (a flexible rubber core reinforced with embedded steel plates). Mounted between the H330’s manual transmission case and the chassis frame, it acts as a “soft buffer” between the vibrating gearbox and the car body. Think of it as the “manual transmission’s shock absorber”—without it, the 变速箱 (transmission)’s vibrations would rattle the cabin, damage the gearbox’s mounting points, and even affect the smoothness of gear shifts.

This transmission cushion is exclusive to Brilliance H330 with manual transmission—always check your vehicle’s transmission type and VIN to confirm fitment! It’s tailored to the H330 MT’s specs: its thickness and rubber hardness match the manual gearbox’s weight (around 40–50kg) and vibration frequency (no flattening or excessive deformation), its mounting holes align perfectly with the H330’s transmission case and chassis brackets (no forced modifications), and its structural design adapts to the MT’s power transmission rhythm (maximizing shock absorption). Grab a generic cushion or one for automatic transmission? You’ll run into trouble: wrong hardness (poor vibration control), mismatched size (can’t install), or insufficient load capacity (breaks easily).

1. Core Jobs: Dampen Vibrations, Support Gearbox & Protect Components

As a vital part of the H330’s manual transmission system, it does three key jobs to keep driving smooth and the gearbox safe:

Absorb transmission vibrations: When the H330’s manual gearbox operates, gear meshing and power transfer generate constant vibrations. The cushion’s rubber core deforms gently to soak up these vibrations, stopping them from spreading to the chassis and cabin—this means less rattling noise inside the car, especially during low-speed driving or gear shifts.

Support the manual gearbox’s weight: The H330’s manual transmission weighs over 40kg, and this cushion bears a large portion of that load. It keeps the gearbox in its correct position (no sagging or shifting when accelerating, decelerating, or driving over bumps), ensuring stable power transfer to the wheels.

Protect transmission mounting & connections: By cushioning the gearbox’s small movements (caused by road jolts or gear changes), it reduces stress on the transmission’s mounting bolts, drive shafts, and shift linkage. This avoids loosening or damage to these parts, which could lead to gear shift failure or transmission leaks.

This 4084859 transmission cushion only fits Brilliance H330 with manual transmission—wrong fit means functional failure or damage:

Fits These: All Brilliance H330 variants equipped with manual transmission (matches the MT’s weight, mounting points, and vibration characteristics—confirm with VIN and transmission type).

Won’t Fit These:

H330 with automatic transmission (AT): AT gearboxes have different weights and mounting positions (cushion can’t support or align).

Other Brilliance models: Like H230, H530, or V5—different transmission designs and chassis layouts (no compatible fit).

Non-Brilliance vehicles: Even if similar in appearance, transmission weight and mounting bolt patterns differ (can’t install or work properly).

H330 with modified transmission: Aftermarket gearbox upgrades change weight/distribution—original cushion can’t adapt, leading to damage.

 Installation & Upkeep (Pros Recommended for Safety)

Installation: Better Handled by Certified Technicians

Replacing this cushion involves supporting the heavy manual gearbox—professional installation avoids risks:

Prep: Techs lift the H330 safely, use a specialized jack to support the manual transmission (prevents it from dropping when removing the old cushion), then disconnect the bolts holding the old cushion to the transmission and chassis.

Remove old cushion: They take out the worn unit, clean the mounting surfaces (wipe off oil, rust, or debris), and check for damage to the transmission case or chassis brackets.

Install new cushion: They align 4084859 with the mounting points (using positioning pins), bolt it to Brilliance’s exact torque specs (too tight crushes the rubber; too loose causes shifting), then lower the transmission gently onto the new cushion.

Test: They start the engine, test all gear shifts for smoothness, and take a test drive to confirm no cabin rattling or transmission movement.

Maintenance: Easy Checks to Extend Lifespan

Inspect rubber condition: Every 30,000km, have techs check if the rubber is cracked, hardened, or swollen (old rubber loses shock absorption). Replace immediately if damaged.

Tighten mounting bolts: During oil changes, ask to check the cushion’s bolts—loose bolts cause the transmission to rattle or shift position, increasing wear.

Keep oil away: Transmission oil or engine oil leaks can degrade the rubber—wipe up any leaks near the cushion right away to avoid damage.

Watch for warning signs: If you feel increased vibration during gear shifts, hear loud rattling from the transmission area, or notice difficulty shifting gears, the cushion is likely worn out.

Summary: Brilliance H330 Manual Transmission (MT) Cushion (4084859)

This is an exclusive transmission cushion for Brilliance H330 with manual transmission (confirm VIN/transmission type for fitment). Made of rubber-metal composite (flexible rubber core + embedded steel plates), it’s mounted between the H330’s MT case and chassis frame.

Its core functions: Absorb gearbox vibrations to reduce cabin rattling (especially during shifts); support the 40–50kg MT to keep it positioned correctly (stable power transfer); protect mounting bolts, drive shafts, and shift linkage from stress/damage.

It only fits H330 MT— incompatible with H330 AT, other Brilliance models (e.g., H230), non-Brilliance vehicles, or modified H330 transmissions. Installation needs certified techs (transmission jack support + torque control). Maintenance includes 30,000km rubber checks, bolt tightening, oil leak prevention, and addressing vibration/shift issues.
