Brilliance H330 Transmission Cushion (AT) – Part No.: 3484859

Let’s keep it straightforward—this isn’t just a random “rubber pad” under your Brilliance H330. It’s the shock absorber for your car’s automatic transmission that keeps rides smooth and protects crucial parts: a tough, flexible piece made of high-density rubber (or a rubber-metal mix) with strong mounting brackets. It sits right between the H330’s automatic transmission and the car’s chassis, acting like a “buffer” that soaks up vibrations and eases impact. Without it, every gear shift, acceleration, or bump in the road would send harsh jolts to the transmission and engine—leading to noisy drives, loose parts, or even early wear and tear.

This transmission cushion is only for Brilliance H330 models with automatic transmission (AT)—always check your vehicle’s VIN to make sure it’s the right fit! It’s made specifically for the H330’s AT: its thickness and flexibility match the transmission’s weight and how much it vibrates (so it doesn’t under or over-dampen), its mounting brackets line up perfectly with the H330’s chassis and transmission bolt holes (no forcing it to fit), and its rubber can handle the AT’s operating temperature (won’t get hard or crack). Grab a generic one or one for a manual H330? You’ll run into problems: wrong stiffness (either too soft to hold the transmission or too hard to absorb shocks), mismatched mounting spots (can’t attach securely), or weak rubber (wears out fast).

1. Core Jobs: Soak Up Shocks, Cut Noise & Hold the Transmission Steady

As a key undercarriage part for H330 AT models, it does three big jobs to protect your car and make drives nicer:

Dampen transmission vibrations: Automatic transmissions vibrate when shifting gears or running. This cushion’s flexible rubber core soaks up those vibrations—stopping them from reaching the chassis and cabin. Without it, you’d feel constant rattling or buzzing, especially when the car’s idling or speeding up.

Absorb road impact: When you drive over potholes, speed bumps, or rough roads, the transmission shifts a little. The cushion acts as a buffer, taking the hit to keep the transmission securely mounted (no metal scraping against metal that damages bolts or the transmission case).

Reduce cabin noise: By blocking vibration transfer, it cuts down on transmission-related noise inside the car. This makes drives quieter—no loud clunks or hums when shifting gears or cruising.

This 3484859 transmission cushion only fits Brilliance H330 automatic transmission models—wrong fit means bad protection and bumpy rides:

Fits These: Brilliance H330 variants with AT (matches the AT’s weight, mounting spots, and vibration needs—confirm with VIN).

Won’t Fit These:

Brilliance H330 manual transmission (MT) models: MT transmissions have different weights and mounting positions (cushion won’t line up or support properly).

Other Brilliance models: Like H230, H320, or V3—different transmission sizes, chassis layouts, or bolt patterns (can’t attach).

Non-Brilliance cars: Even if it looks similar, their AT specs and mounting spots are different (no functional fit; causes vibrations).

H330 with modified transmissions: Aftermarket AT swaps or performance upgrades change the transmission’s weight and vibration—original cushion can’t adapt (fails to soak up shocks).

Installation & Upkeep (Pros Recommended—Safety First!)

Installation: Best Done by Certified Technicians

Replacing this cushion means lifting the car and supporting the transmission—doing it yourself risks damage:

Prep: Safely lift the H330 (use jack stands), hold the transmission up with a support brace (so it doesn’t drop), then find the old cushion (between the transmission and chassis).

Remove old cushion: Techs unbolt the mounting brackets from the transmission and chassis, then pull out the old cushion (check for cracks or hard rubber).

Install new cushion: They line up 3484859 with the mounting spots, bolt it securely to the transmission and chassis (tighten to Brilliance’s specs), then take off the support brace.

Test: They lower the car, start the engine, and test drive—checking for less vibration, no clunking noises, and smooth shifting (to make sure it fits and works right).

Maintenance: Easy Checks to Avoid Breakdowns

Inspect every 40,000 km: Look for cracks, hardening, or wear on the rubber (hard rubber can’t absorb shocks—replace right away).

Check bolts yearly: Make sure the mounting bolts are tight (loose bolts cause rattling or misalignment—tighten if needed).

Watch for warning signs: If you feel too much vibration, hear clunking when shifting, or notice the transmission sagging, the cushion is failing (replace fast to protect the transmission).

Don’t overload the car: Don’t carry more weight than the H330’s max capacity—extra load strains the cushion (shortens its life).

Summary: Brilliance H330 AT Transmission Cushion (3484859)

This transmission cushion only works for Brilliance H330 cars with automatic transmission (AT)—make sure to check your vehicle’s VIN to confirm it’s the right one! It’s a tough, bendy piece made of high-density rubber (or a rubber-metal combo) and has strong mounting brackets. It sits right between the H330’s automatic transmission and the car’s chassis, working as a shock absorber.

Here’s what it does: First, it soaks up vibrations from the transmission—stops your car’s interior from rattling. Second, it takes the hit from rough roads (like potholes or speed bumps) to keep the transmission’s bolts and case safe from scraping metal. Third, it cuts down on transmission noise inside the car, making drives quieter.

It works for all H330 AT versions, but don’t try putting it on H330 manual models, other Brilliance cars (like the H230 or H320), cars from other brands, or H330s with modified transmissions—it won’t fit right.

It’s best to have a pro install it: they’ll lift the car, hold up the transmission (so it doesn’t drop), swap out the old cushion for this 3484859 one, then test to make sure shifting feels smooth.

For upkeep: Every 40,000 km, check the rubber for cracks or wear; make sure the bolts are tight once a year. If you feel extra vibration or hear clunking when shifting, that’s a sign it’s going bad—replace it fast. Also, don’t overload the car—too much weight strains the cushion.

Genuine cushions fit right, handle heat well, and last long. Aftermarket ones? They might not absorb shocks well, fit poorly, or wear out fast—so they’re not worth the hassle.
