Description
Performance 46RE transmission
- The improved valve body features upgraded throttle, manual, 4-spool switch, and pressure regulator valves to improve shift response, enhance lubrication, and support long-term transmission performance.
- A modified valve body enables torque converter charge while in park, increasing system durability and allowing for smoother initial gear engagement.
- Each high-performance torque converter is tested for proper lockup, balance, concentricity, and sealing. Enhanced beyond OE standards, preventing front seal leaks, bushing wear, and vibration. Diesel and HD gas versions receive upgraded lock-up linings.
- The pump ensures consistent internal pressure, eliminating common problems like delayed engagement and slipping between gears.
- The overdrive direct clutch pack is upgraded to include eight plates and a new thrust plate, delivering stronger hold and extended durability under load.
- The OD clutch is built with a four-plate configuration to improve torque handling and long-term performance.
- A 5-pinion overdrive planetary assembly replaces the factory unit, providing increased torque capacity and overall drivetrain strength.
- An oversized Low/Reverse band strut helps maintain correct band clearance, solving drum slippage issues and preventing No-Reverse failures.
- The output shaft is custom-machined to accept both early and late-style yokes, offering broader compatibility across applications.
- An upgraded external transmission cooler is included to help reduce operating temperature, extend fluid life, and prevent overheating-related damage.
- Custom-spec bushings improve hydraulic control and enhance fluid routing throughout the transmission for more reliable performance.
- All bushing and machined surfaces are polished to a fine OE-grade finish of 16 RA or better, ensuring reduced friction and smoother component operation.
- Every transmission undergoes full hot and cold testing on a specialized dynamometer using synthetic transmission fluid and a high-efficiency filtration system to verify performance before shipment.
