Product Overview

The transmission mount, OEM number 21832-4H500, is the transmission mounting insulator fitted to the Hyundai H1 and Grand Starex, 2.4L engine, model years 2007 onward. This is the companion mount to the engine mounting insulator used on the same platform, and given how widely this van is used in commercial and fleet applications, it's a steady, recurring part to stock alongside the matching engine mount.

Worn or failing units typically show up as excessive vibration felt through the cabin, a clunking noise when shifting gears, or noticeable transmission movement under acceleration or braking. GSK Auto manufactures this transmission mount to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your VIN or chassis code before ordering - this mount is commonly needed alongside the corresponding engine mount (21812-4H200), so it's worth confirming with your customer whether they need both parts for a complete mounting job.)

What Is a Transmission Mount?

Function: The transmission mount secures the transmission to the vehicle's frame or subframe while absorbing vibration and movement generated during gear changes and engine torque transfer, working alongside the engine mounts to keep the powertrain assembly stable.

Working Principle: A rubber mounting element between the transmission housing and the frame flexes to absorb torque reaction and vibration as the transmission shifts gears and transfers power, while still holding the transmission securely in position.

Importance: On a commercial van platform like the H1/Grand Starex, the transmission mount has to handle sustained load from cargo weight and daily fleet use, so a failing mount can accelerate wear on nearby components not designed to handle the extra movement.

Common Failures & Signs: Rubber material cracking, tearing, or breaking down from age and heat exposure. Excessive vibration felt through the cabin, especially during gear changes. Clunking or knocking noise when shifting into gear. Noticeable transmission movement visible under the vehicle during acceleration or braking.
