Features:

• The solenoid pack, commonly responsible for electrical shift related issues in this family, has been completely remanufactured in-house, including disassembly, cleaning, and testing independently.
• To prevent overdrive planet failure due to lack of lubrication and to increase durability, the planets have been rebuilt and TIG welded.
• To combat erratic shifting due to high wear, the servo and servo pin have been realigned and modified using inhouse custom tooling and bushings.
• The completely remanufactured pump, with a new pump cover bushing machined in place and a new flow control valve, has been assembled in a custom alignment fixture to provide consistent internal pressures, improved lubrication, and eliminate noise, slipping, and delayed engagement.
• To prevent torque converter vibration and damage, we have provided, installed, and aligned a flex plate adapter.
• The pump also features a custom-spec front stator bushing and a new rear bushing to better support the input shaft and improve lubrication control.
• Fully tested on our custom-built, custom-programmed dynamometers with Synthetec ATF, the 5R55S/W is cold-, hot-, load-, and road-tested.
• Every transmission is cold-and hot-tested using a proprietary dynamometer testing program that includes fully synthetic automatic transmission fluid and a filtration system
