Will this mount fit my transmission and chassis?

This universal mount is designed to work with most GM rear-wheel-drive transmissions listed: TH350, TH400, 700R4, 4L60E and 4L80E. The mounting slots provide lateral adjustment so the same unit can align with a variety of crossmember and tailshaft positions.

• Compatible with common GM transmissions noted above
• Mounting slot range: 3.25" to 4.75" for flexible placement
• Works with many factory and aftermarket crossmembers
• Universal design reduces need for multiple part numbers

How durable is the construction and how was it tested?

The mount is manufactured from high-grade raw materials selected for strength and longevity, then subjected to testing to ensure it meets or exceeds the original mount's performance characteristics. Expect robust metal components and a bonded elastomer that resists fatigue under load.

• High-quality steel and reinforced bonding points
• Elastomer tuned to absorb vibration while resisting oil and heat
• Tested to match or surpass OEM mount specifications
• Designed for heavy-duty and street/strip use cases

How do I install and position the mount for best results?

Installation is straightforward for experienced mechanics and competent DIYers: position the mount under the transmission tailhousing, align the crossmember bolt pattern, and use the slotted holes to fine-tune fore/aft alignment. Torque hardware to vehicle manufacturer specs and check driveline angles after installation.

• Align mount to transmission tailhousing and crossmember
• Use 3.25"–4.75" slot adjustment to center the driveline
• Tighten bolts to recommended torque for safety and longevity
• Verify driveline angle and clearances before final test drive

What benefits will I notice after replacing a worn mount?

Swapping a degraded mount for this heavy-duty universal unit reduces drivetrain movement, stabilizes shifting, and helps prevent damage to the driveshaft and transmission. You’ll experience firmer engagement, fewer vibrations, and improved alignment that protects surrounding components.

• Reduced transmission movement under load and during gear changes
• Lower NVH (noise, vibration, harshness) in the cabin and driveline
• Improved longevity for driveshaft, universal joints, and crossmembers
• Versatile fit means fewer special-order parts for common GM swaps

Who is this for: mechanics, performance builders, and DIY enthusiasts working on GM rear-wheel-drive projects who need a dependable, adjustable transmission mount. Whether restoring a classic, upgrading to overdrive conversions, or replacing a failed OEM mount, this WIT WHATEVER IT TAKES TRANSMISSION PARTS, INC universal mount offers a practical, heavy-duty solution that balances strength, adjustability, and value.
