Premium Remanufactured Automatic Transmission

Professionally remanufactured automatic transmission assembly with all new seals, gaskets, and friction components. Precision inspected, rebuilt to OEM specs, and dyno tested for smooth shifting and lasting reliability.

Each transmission undergoes rigorous dyno testing to verify precise hydraulic pressures, smooth shifting, torque converter function, and park lock operation—guaranteeing reliable, trouble-free driving.

Every transmission is fully disassembled, cleaned, and rebuilt using 100% upgraded heavy-duty seals, friction components, solenoids, and torque converter parts to ensure maximum durability and performance.

All transmissions are completely disassembled and cleaned. All cases are media blasted. Internal parts are inspected for wear or damage and replaced as required. All bushings are inspected and replaced as required. All of friction components are replaced with upgraded heavy duty parts. Drum assemblies are air checked and side play is checked to assure proper clearance. All of seals, o’rings and gaskets are replaced. All of solenoids are checked and replaced if they do not pass duty cycle tests. Internal wiring harness are checked and replaced as necessary.  Valve bodies are disassembled, cleaned, and measured for wear. Valve body valves and valve bores are inspected and valve bores are machined as required. Completed valve bodies are tested for proper operation prior to dyno testing.  Transmissions are assembled, end plays are set and fasteners are torqued to the required specification. All of transmissions are dynamometer tested to ensure proper pressures and shift quality throughout the operating range.  All upshifts and downshifts are checked against preset parameters.  Torque converter stall speed and lockup is verified on the dyno test.  Transmission park locking mechanism is checked during dyno test. (where applicable). [Torque Converter] All of converters are dynamic balanced  All of pumps are furnaced brazed. All new bearings and o’rings. All new springs and rollers in stator. All new thrust washers. All new friction liners in overdrive lockup converters. Converter endplay and hub/pump runout and diameter is checked

• 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’re 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.

• Wear-prone rear stator bushing completely replaced to prevent failure of the E clutch.
• Each valve body is remanufactured and vacuum tested to verify hydraulic control.
• Valve body accumulator dampers are replaced to combat known deterioration of the OE component.
• Fully remanufactured torque converter is tested for leaks, lock-up, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibility of front seal leaks, premature bushing wear, and vibration.
• All wear-prone valves in the completely remanufactured valve body are restored to stringent specifications and vacuum tested to verify proper function.
• Build specifications are checked by four different specialized technicians during the remanufacturing process to verify the correct application.
• Every transmission is cold-and hot-tested using a proprietary dynamometer testing program that includes fully synthetic automatic transmission fluid and a filtration system.
