The Prothane Motion Control Transmission Mount 1-1601-BL is a polyurethane replacement mount designed for GM vehicles with TH350, TH400, 700R4, and 4L60 transmissions. If your factory rubber mount has collapsed, allowing the transmission to sag and misalign the driveline, this black polyurethane mount restores proper geometry and eliminates driveline vibration.

Molded from advanced polyurethane with a durometer rating of 85 Shore A—firmer than factory rubber but without the harshness of solid aluminum. The mount replaces the stock unit with a direct bolt-in design requiring no modifications. It maintains the same mounting dimensions as the OEM part for a perfect fit. The black finish matches factory appearance while providing superior oil and chemical resistance.

A worn transmission mount allows the drivetrain to shift under load, changing the pinion angle and creating vibration that can be mistaken for a bad u-joint or driveshaft imbalance. The Prothane 1-1601-BL locks the transmission in place, maintaining proper driveline angles even under hard acceleration. The polyurethane material resists the oil and heat degradation that turns rubber mounts to mush.

Don't let a sagging mount cause driveline issues. Replace it with Prothane 1-1601-BL and get your geometry back. Order today.

Frequently Asked Questions

What is the durometer rating of the Prothane 1-1601-BL polyurethane transmission mount?

The Prothane Motion Control 1-1601-BL transmission mount is made from high-durometer polyurethane with a rating of approximately 75 to 85 Shore A, which is significantly stiffer than the factory rubber mount that typically measures around 50 to 60 Shore A. The increased stiffness reduces drivetrain movement under hard acceleration and braking, improving shift feel and preventing the transmission from rocking against the crossmember. The mount is black in color and matches the factory mounting pattern for direct bolt-in installation.

Will the Prothane polyurethane transmission mount increase noise and vibration in my truck?

The Prothane 1-1601-BL polyurethane transmission mount may transmit slightly more vibration and drivetrain noise into the cabin compared to a soft factory rubber mount, but the increase is typically minimal in trucks where the transmission is already mounted relatively solidly. The polyurethane material dampens high-frequency vibrations better than solid metal mounts while still controlling drivetrain movement. If NVH is a concern, Prothane offers a lower-durometer version that balances performance and comfort.

Does the Prothane 1-1601-BL mount fit both automatic and manual transmissions?

The Prothane 1-1601-BL transmission mount is designed to fit specific vehicle applications, and the mount pad shape and bolt pattern differ between automatic and manual transmissions in many vehicles. Prothane lists the specific transmission types compatible with each mount part number. Always confirm whether your vehicle uses a separate mount pad for the automatic transmission versus the manual transmission crossmember mount location.

How do I install the Prothane polyurethane transmission mount in my truck?

Installing the Prothane 1-1601-BL transmission mount involves supporting the transmission with a floor jack, removing the center bolt that fastens the mount to the crossmember, unbolting the crossmember from the frame, and replacing the rubber mount with the polyurethane unit. The mount bolts into the factory locations using the existing hardware. Torque the transmission-to-mount bolts to 30 to 50 foot-pounds and the crossmember-to-frame bolts to factory specifications.

What vehicles are compatible with the Prothane 1-1601-BL transmission mount?

The Prothane Motion Control 1-1601-BL transmission mount fits a range of GM and Ford trucks and SUVs, including Chevy Silverado, GMC Sierra, Ford F-150, and similar body-on-frame vehicles from the 1990s through the 2010s. The mount is vehicle-specific, so check Prothane's application guide for your exact year, make, model, engine, and transmission combination. Using the correct mount prevents misalignment of the transmission output shaft relative to the pinion flange.

What is the advantage of a polyurethane transmission mount over a stock rubber mount?

A polyurethane transmission mount like the Prothane 1-1601-BL reduces drivetrain deflection by approximately 50 to 70 percent compared to a stock rubber mount, which improves shift quality, reduces driveline clunk, and maintains consistent pinion angle during hard acceleration. Rubber mounts compress and sag over time, allowing the transmission to settle and change the driveshaft working angle. Polyurethane mounts resist compression set and maintain their shape for years of service.
