What transmission does a 2014 Silverado 1500 have?

A 2014 Silverado 1500 uses a six-speed automatic transmission. Most V8 models pair with GM’s 6L80-E, while the 4.3L V6 typically uses the 6L50-E.

In this article, we break down how Chevrolet matched transmissions to the engines for the 2014 Silverado 1500 and what that means for drivers, buyers, and maintenance.

Transmission options by engine

Before listing the specific pairings, note that axle ratio, drivetrain (2WD vs. 4WD), and model year refinements can influence final drive components, but the core transmission choices fall along engine lines.

4.3L V6: GM 6L50-E six-speed automatic

5.3L V8: GM 6L80-E six-speed automatic

6.2L V8: GM 6L80-E six-speed automatic

All configurations share the same basic six-speed automatic physics, with the 6L80-E handling higher torque from the V8 engines and the 6L50-E suited to the lighter torque profile of the V6.

Details on the designations

The "6L" designation indicates a six-speed automatic with a longitudinal layout; the trailing numbers (50 or 80) indicate different gear sets and torque capacities, and the "E" marks electronic control. In the 2014 Silverado 1500 lineup, these transmissions were paired with the available engines as described above.

Summary: For a 2014 Silverado 1500, expect a six-speed automatic transmission. The 4.3L V6 generally uses the 6L50-E, while the 5.3L and 6.2L V8 engines use the 6L80-E. Both 2WD and 4WD configurations employ these transmissions, with the 6L80-E typically used on the higher-torque V8s.

How do I know if I have a 6L80 or 6L90?

The main ways to identify a 6L80 from a 6L90 are by the RPO code (6L80=MYC, 6L90=MYD), the length, and the pan shape. The 6L90 is a heavier-duty version that is approximately 1-3/8 inches longer and has a pan with a flatter corner, while the 6L80 is shorter and has a more rounded pan corner. You can also check the part numbers or look at specific internal components if you have the transmission disassembled.

RPO Code: Look for the RPO (Regular Production Option) code on the glovebox or vehicle service tag.
- MYC: indicates a 6L80.
- MYD: indicates a 6L90.
Transmission Length: The 6L90 is longer than the 6L80.
- 6L80: Case with bell housing length is approximately 23.5 inches.
- 6L90: Case with bell housing length is approximately 25 inches (1-3/8 inches longer).
Transmission Pan: The shape of the transmission pan is a reliable indicator when the unit is out of the vehicle.
- 6L80: The pan has a rounded corner on the back.
- 6L90: The pan has a flatter corner on the back.
Part Numbers: GM part numbers for transmission parts often begin with 242. The specific part number on the TEHCM sticker (under the transmission pan) can help identify the exact model and year.
