About the 6L80E & Common Problems

6L80E Transmission

With horsepower and torque outputs on the rise, GM needed a modern transmission that could handle up to 664 lb-ft of torque, while still maintaining the government mandated fuel economy figures. To do this, General Motors created an all-new electronically controlled 6-speed automatic transmission that could be controlled manually with paddle shifters or the gear stick.

The new 6L80E transmission (6-speed / Longitudinal / 8,000 lb vehicle weight / Electronically controlled) was introduced in 2005, and found its way into cars like the Corvette, Cadillac CTS-V, and the Chevrolet Camaro ZL1.

Unlike previous versions, this new 6-speed didn’t come with a direct-drive function, but it featured 2 overdrive gears for better fuel economy, along with a direct clutch-to-clutch system that could change gears without using bands.

  • Parking PrawlReverse Fails to Engage
    If you’ve selected Reverse and your vehicle still won’t move, then it’s possible the park prawl (the metal piece that stops your vehicle from rolling), or one of the clutches has become damaged.
  • Slipping Between Gears
    If you experience slipping in reverse, or between 2-3, then it’s very likely that the 1-2-3-3/5-R drum has developed a crack, which will require an entirely new drum and bearing.
  • Slipping in First Gear
    If you have difficulty getting your vehicle to move from a dead stop, then it’s possible that one of the solenoids is stuck in the ‘off’ position, or there’s a problem inside of the valve body.

Used vs. Rebuilt vs. Remanufactured

If you’re having problems with your 6L80E you’re going to want the most economical solution.

A rebuilt 6L80E will only have a certain number of components that get replaced. So the service life is limited, and the warranty will only last 1-2 years.

A used 6L80E is pulled from a wrecked vehicle, so there’s no telling what may be wrong with it, or how long it will last.

A remanufactured transmission on the other hand, is completely remanufactured, and it’s designed to exceed the manufacturer’s original specifications. That way you get a longer service life, along with a 3-year/Unlimited Mile Nationwide Warranty.’

Watch the Remanufacturing Process

Remanufactured 6L80E Transmission Updates and Upgrades

Although the 6L80E transmission was designed to handle high horsepower/torque applications, they can wear out rather quickly. To combat the many shortcomings of this gearbox, Street Smart Transmission upgrades many key internal components during the remanufacturing process. Some of these enhancements include:

  • A remanufactured valve body that’s been upgraded with system correction and recalibration kits
  • An upgraded pump with machined pump body mating surfaces and a resurfaced pump rotor to maintain proper fluid pressure
  • To prevent front seal leaks, premature bushing wear, and vibration, all remanufactured 6L80E torque converters come with an updated stator support shaft and seal rings, then each is fully tested for leaks, concentricity, lockup and balance
  • To improve holding capacity, an upgrade 38-element low sprag is used
  • To bring the control software up to date, the Transmission Control Module is reflashed to include the latest calibrations based on the VIN number
  • To improve fluid pressure and internal fluid flow control, upgraded bushings are installed
  • All the bushings and machined surfaces get polished to a mirror-like finish of at least 15 RA
  • Each remanufactured 6L80E transmission receives a complete system correction and recalibration kit, including updated servos, valve body accumulators, and PR system components
