Converter & Pump
TCC slip, shudder or failure can damage the converter hub, pump, stator support and bushings while distributing debris.
- Converter clutch material
- Pump rotor and slide condition
- Bushing and sealing surfaces
GM 6L80 & 6L90
Converter debris can turn a 6L80 or 6L90 complaint into a complete-system repair.
Integrity primarily offers professionally remanufactured 6L80 and 6L90 replacement packages, with selective rebuild options when the unit and repair scope make sense.
Supported Units
The six-speed GM family needs more than a clutch kit after major failure.
The 6L80 and heavier-duty 6L90 are used in many GM rear-wheel-drive cars, SUVs, vans and trucks. Their torque converter clutch can shed friction material and metal, contaminating the pump, valve body, bushings, clutches, cooler and lines before the vehicle loses all movement.
Other concerns can involve pump and stator-support wear, clutch drums, planetary components, valve-body cross leaks, solenoid performance and the transmission electro-hydraulic control module. The teardown must determine how far debris and heat traveled.
For many applications, a complete remanufactured replacement offers the most predictable combination of updated components, testing and warranty. Installation must still include the approved converter, cooler procedure, correct fluid level, programming and adaptive relearn.
What Matters
6L80 and 6L90 areas that change the scope.
One code or symptom does not show the full debris path; fluid and internal condition matter.
Clutches & Hard Parts
Heat and pressure loss may damage clutch packs, drums, shafts and planetary components beyond standard rebuild material.
- Clutch and steel heat
- Drum and snap-ring areas
- Planetary and bearing debris
Controls & Setup
TEHCM, valve-body wear, solenoids, software and adaptive values affect operation after mechanical work.
- Module compatibility
- Programming and setup
- Fast-learn/adaptive procedure

Common Questions
Answers before you schedule.
These answers provide a starting point. The vehicle, evidence, written quote and warranty terms control the final recommendation.
What is a common 6L80 failure?
Torque converter clutch deterioration is common and can send material through the transmission. Pump, valve-body, clutch and hard-part damage may follow.
Can a 6L80 be rebuilt after converter failure?
Sometimes, but the final scope depends on debris and hard-part condition. A quality reman replacement may be more predictable when contamination is extensive.
Does a replacement 6L80 need programming?
Many applications require module programming, setup or strategy handling plus an adaptive/fast-learn procedure. Exact requirements depend on what electronics are supplied and the vehicle.
What is the difference between a 6L80 and 6L90?
They are related GM six-speed units, but the 6L90 is designed for higher-capacity applications and has important internal and interchange differences. They should not be treated as the same assembly.
