2016 Chevrolet Malibu Transmission & Axle Gear Ratios

Transmission gear ratios

The 2016 Chevrolet Malibu offered a few transmission options, each designed to optimize performance and fuel efficiency for its intended application.

6-Speed Automatic Transmission (M5U / M5D)

This transmission was paired with the 1.5L turbocharged and 2.5L naturally aspirated engines.

8-Speed Automatic Transmission (M5T)

This transmission was exclusively paired with the more powerful 2.0L turbocharged engine.

Continuously Variable Transmission (CVT) - Hybrid

The Malibu Hybrid utilized a Voltec-based two-motor drive unit that functions as an electronic continuously variable transmission.

Available axle ratios

Unlike many trucks or SUVs, most passenger cars like the 2016 Chevrolet Malibu come with a fixed final drive ratio that is integrated within the transaxle and is specific to the engine and transmission combination. Therefore, there isn't a range of "axle ratios" to choose from in the traditional sense that you might find in a truck. However, we can refer to the final drive ratios for each powertrain option.

How to identify your axle ratio

For most passenger cars like the 2016 Chevrolet Malibu, the "axle ratio" (more accurately, the final drive ratio) is determined by the specific transmission and engine combination. You typically won't find a separate axle tag as you would on a truck's differential. The easiest way to confirm your vehicle's powertrain configuration and thus its final drive ratio is by checking the Service Parts Identification (SPID) sticker, commonly found in the glove compartment or on the driver's side door jamb. Look for the RPO (Regular Production Option) codes listed there, such as FX3, FY6, or FLC, which directly correspond to the final drive ratio for your vehicle's specific setup.

Towing vs MPG impact

In passenger vehicles, while a higher (numerically larger) final drive ratio generally provides quicker acceleration and slightly better towing performance by allowing the engine to reach its power band faster, it usually comes at the expense of fuel economy due to higher engine RPMs at cruising speeds. Conversely, a lower (numerically smaller) final drive ratio will result in lower engine RPMs at cruising speeds, leading to better fuel economy, but with a slight compromise in off-the-line acceleration and pulling power. Since the Malibu is not designed for significant towing, the final drive ratios are primarily optimized for a balance of acceleration and fuel efficiency. The Hybrid model, with its lower final drive ratio, is clearly geared towards maximizing fuel economy.

Common issues

While the conventional automatic transmissions in the 2016 Malibu are generally reliable, some owners have reported issues, particularly with the 8-speed automatic (GM 8L45), exhibiting occasional harsh shifts or hesitation. For the 6-speed automatic, issues are less common, but like any transmission, proper fluid maintenance is key to longevity. The CVT in the Hybrid model is generally robust, but as with all CVTs, it's critical to adhere to manufacturer-recommended service intervals.

Ring & Pinion Whine

As the Malibu uses a transaxle, a separate ring and pinion issue is less common than in rear-wheel-drive vehicles with a distinct differential. However, internal transmission gear whine can sometimes be mistaken for an axle issue.

Carrier Bearing

Bearing wear within the transaxle can manifest as unusual noises, but this is typically part of a broader transmission issue rather than a standalone "carrier bearing" problem in the context of a separate differential.

Limited-Slip Clutch Wear

The 2016 Chevrolet Malibu does not typically come equipped with a limited-slip differential. Therefore, wear related to limited-slip clutches is not a concern for these vehicles.
