P2M Solid Polyurethane Transmission Mount – Nissan S13 / S14 / S15 | SR20 / KA24 / CA18 | HRC-80 Hardness Urethane

The P2M Solid Polyurethane Transmission Mount for the Nissan S13, S14, and S15 is a direct-fit solid urethane transmission mount upgrade — replacing the factory rubber transmission mount with a solid HRC-80 hardness urethane unit that eliminates excessive transmission movement at high RPM and high horsepower output, improves shift precision, and improves power transfer to the rear wheels. Compatible with the SR20DET, KA24DE, and CA18DET engines — the three most common engine configurations in the S-chassis Nissan platform. Phase 2 Motortrend (P2M) is a respected JDM performance and accessories brand known for their quality drivetrain, suspension, and interior accessories for popular Japanese performance platforms.

Key Features:

• Solid HRC-80 urethane construction — manufactured from HRC-80 hardness urethane — a solid mount that eliminates the compliance and deflection of the factory rubber mount under high-load conditions
• Eliminates excessive transmission movement — the factory rubber transmission mount allows the transmission to move excessively under high RPM and high torque loads — the P2M solid urethane mount keeps the transmission firmly in position under all operating conditions
• Improved shift precision — a transmission that moves under load causes inconsistent shifter feel and can contribute to missed shifts — the solid mount keeps the transmission steady for more consistent, precise gear changes
• Improved power transfer — keeping the transmission steady reduces drivetrain flex and improves the efficiency of power transfer from the engine to the rear wheels — a meaningful improvement on high-horsepower S-chassis builds
• SR20 / KA24 / CA18 compatible — correct for S13, S14, and S15 applications running the SR20DET, KA24DE, or CA18DET engine
• Direct-fit — engineered for direct-fit installation in the S13, S14, and S15 transmission tunnel — uses the factory mounting points
• P2M quality — manufactured by Phase 2 Motortrend, a respected JDM performance brand

Why a Solid Transmission Mount on the S-Chassis?

• Factory Rubber Mount Limitations: The factory S-chassis transmission mount uses a rubber bushing that provides compliance — absorbing vibration and reducing NVH (noise, vibration, harshness) for a comfortable street driving experience. However, this compliance allows the transmission to move under high torque loads — particularly on modified S-chassis builds with increased power output. Transmission movement under load causes inconsistent shifter feel, contributes to missed shifts, and reduces the efficiency of power transfer to the rear wheels.
• Solid Mount Advantage: The P2M HRC-80 urethane solid mount eliminates transmission movement entirely — the transmission stays firmly in position under all operating conditions. The result is more consistent, precise shifter feel, reduced missed shifts, and improved power transfer efficiency. On a high-horsepower SR20DET, KA24DE, or CA18DET build, the solid transmission mount is a foundational drivetrain upgrade.
• NVH Trade-off: A solid transmission mount will transmit more drivetrain vibration into the cabin than the factory rubber mount — this is the expected trade-off for improved performance. On a dedicated performance or drift build, this trade-off is acceptable and expected. For daily-driven S-chassis builds, the increased NVH should be considered before installing a solid mount.
• S-Chassis Context: The Nissan S13, S14, and S15 are among the most popular drift and performance platforms in the world — platforms where drivetrain rigidity, shift precision, and power transfer efficiency are critical for competitive performance. A solid transmission mount is a standard upgrade on any serious S-chassis performance build.

Specifications:

• Brand: Phase 2 Motortrend (P2M)
• Part Number: P2-TMKNS13-HC
• Material: Solid HRC-80 hardness urethane
• Type: Solid transmission mount
• Engine Compatibility: SR20DET / KA24DE / CA18DET
• Application: Nissan S13 (240SX / 180SX / Silvia) / S14 (240SX / Silvia) / S15 (Silvia)

Fitment Information:

• Nissan S13 — 240SX / 180SX / Silvia — SR20DET / KA24DE / CA18DET
• Nissan S14 — 240SX / Silvia — SR20DET / KA24DE
• Nissan S15 — Silvia — SR20DET
• Direct-fit — uses factory transmission mount mounting points
• Note: Verify your specific S-chassis model and engine configuration before ordering. A solid transmission mount will increase drivetrain NVH compared to the factory rubber mount — this is expected and acceptable on a performance build. Professional installation recommended.

What's Included:

• P2M solid polyurethane transmission mount — HRC-80 urethane — Nissan S13/S14/S15 SR20/KA24/CA18 (P2-TMKNS13-HC)
• Refer to P2M's product documentation for complete hardware contents

Installation Notes:

• Professional installation recommended — transmission mount replacement requires supporting the transmission during mount removal and installation
• Support the transmission with a transmission jack or suitable support before removing the factory mount — the transmission must be supported to prevent damage to the gearbox and surrounding components during mount replacement
• Torque all mounting hardware to the correct specification — refer to P2M's installation documentation for correct torque values
• Inspect the engine mount and other drivetrain mounts during installation — worn mounts should be replaced alongside the transmission mount for a complete drivetrain mount refresh

Why P2M?

Phase 2 Motortrend (P2M) is a respected JDM performance and accessories brand known for their quality drivetrain, suspension, and interior accessories for popular Japanese performance platforms including the Nissan S-chassis, Honda Civic, and other JDM favourites. P2M's solid transmission mount is a popular and proven upgrade in the S-chassis community — a quality, direct-fit solid urethane mount that delivers the shift precision and drivetrain rigidity that serious S-chassis performance builds demand. For S13, S14, and S15 owners who want a quality solid transmission mount from a brand that understands the JDM performance community, P2M is the correct choice.

Perfect For:

• Nissan S13, S14, and S15 owners running SR20DET, KA24DE, or CA18DET engines who want to eliminate excessive transmission movement, improve shift precision, and improve power transfer efficiency with P2M's HRC-80 solid urethane transmission mount
• S-chassis drift and performance builds where drivetrain rigidity and shift precision are critical — a solid transmission mount is a foundational upgrade for any serious S-chassis performance build
• High-horsepower S-chassis builds where the factory rubber mount's compliance allows excessive transmission movement under the increased torque loads of a modified SR20DET, KA24DE, or CA18DET

Note: Solid mount — increased drivetrain NVH compared to factory rubber mount is expected and normal. Verify S-chassis model and engine configuration before ordering. Support transmission before removing factory mount. Professional installation recommended.
