We Offer Jasper Transmission Installation

JASPER® Transmission Process

 THOROUGH CLEANING
Every JASPER® reman transmission is thoroughly disassembled then cleaned to remove contaminants that result in premature wear to gears, bearings, shafts and other precision components like the valve body. Transmission cleaning includes individual component hand washing. Parts are carefully inspected and bushing surfaces are polished to a micro finish for extended bushing life.

EXACT TOLERANCES
As transmission technology advances, the need to maintain exacting tolerances becomes increasingly important which they are very thorough and precise. The machining processes are critical to assure proper operating pressures and provide for a long service life from your JASPER® Remanufactured Transmission such as:

  • Case and valve body resurfacing along with profilometer inspection of the shaft finish that enables JASPER® to maintain exact standards and precise tolerances in all phases of transmission remanufacturing.
  • The front pump and gears are carefully gauged and, if exact tolerances are not met, machined to assure they meet their high standards and precise operation.
  • Updates to specific transmissions such as the 5R110 for which JASPER® installs a machine-in-place bushing in the pump housing to provide correct alignment between the pump housing and converter hub.

TORQUE CONVERTERS
Torque converters are cut open to allow for a thorough cleaning, accurate inspection and the replacement of washers, spacers, springs, rollers, and a new or re-lined lock-up clutch piston as applicable. Turbine fins are inspected and retightened and welded on specific applications. Hubs are carefully inspected and replaced. Converters are pressure tested then dynamically balanced to eliminate vibration that could cause noise, leaks or transmission damage.

VALVE BODIES
Valve bodies are disassembled, cleaned and remanufactured by skilled technicians. All components of the valve body are inspected for wear and the valve body is resurfaced for correct mating and sealing with the transmission case.

VALVE BODY TESTING
Valve bodies are tested on an Answermatic test unit which simulates actual vehicle operation. Vehicle speed and driver demand are varied hydraulically. The Answermatic quickly locates cracks and imperfections and verifies accurate shift points.

TRANSMISSION PRE-INSPECTION
Transmission performance is pre-inspected at the assembly station to assure correct operation before additional assembly and testing is performed. Pressurized fluid and special fixtures are used to test circuit leakage.

NEW PARTS
JASPER® remanufactured transmissions receive a standard set of new and qualified parts. Their standard parts replacement assures smooth, consistent performance and long unit life. JASPER® remanufactured transmissions are assembled by skilled technicians many of whom are ASE Certified and who specialize in particular models or families.

DYNAMOMETER TESTING
Every JASPER® domestic automatic reman transmission is dynamometer tested with recorded inspections to shift patterns and shift pressures. A stall test, fluid leak test, lockup test (as applicable) and park test are performed. Tests are made at varying RPM's and at full and closed throttle positions. Standard transmissions are tested at the work station for proper gear engagement as well as for gear and bearing noise and proper engagement of the shift rails into the detents.

QUALITY CONTROL
Consistent quality is maintained through a continuous training program of ASE technicians backed with statistical process control. Technicians are also JASPER® Certified to specific transmissions and job functions. Weekly disassembly of a production transmission is also performed. All areas of the transmission are scrutinized for cleanliness, surface finishes quality, lubrication, clearance and wears patterns.

3 YEAR | 100,000 MILE WARRANTY PARTS & LABORJASPER® provides an exceptional warranty on their remanufactured automatic and standard transmissions because every one of them goes through their extensive "Do It Right" process that ensures worry-free operation. They also offer an optional Premium Service Plan which provides allowances for such items as towing, car rental, fluids, and premium labor should a problem arise.
