2020 Dodge Charger: Four Transmissions and Gear Ratios Detailed

The 2020 Dodge Charger is only offered with an 8-speed automatic, but there are actually four different automatic gearboxes offered across the lineup.

As we continue with our in-depth coverage of the 2020 Dodge Charger lineup, today we look at the transmissions at work in this popular sport sedan. While this will continue to disappoint the purists who have been calling for a modern Charger with a manual transmission since the car was reintroduced for the 2006 model year, the four-door Dodge is still an automatic-only affair, but across the model lineup, there are four different automatic transmissions at work.

Today, we bring you a look at the basic figures for each of the four transmissions offered in the 2020 Dodge Charger, including transmission gearing and rear end gear ratios.

Dodge Charger V6 Transmissions
The “base model” 2020 Dodge Charger is the SXT, powered by the 3.6-liter Pentastar V6. As mentioned in our piece where we looked at each of the engines, this efficient mill provides 292 horsepower in the SXT while the Charger GT offers 300 horsepower. In all of these rear-drive sedans with the V6, the power is sent towards the rear wheels by means of a TorqueFlite ZF 8HP50 8-speed automatic and a standard 2.62 rear gear set, while a 3.08 rear gear is optional. Individual transmission gear ratios are as follows.

1st 4.71
2nd 3.14
3rd 2.10
4th 1.67
5th 1.29
6th 1.00
7th 0.84
8th 0.67
Reverse 3.30

The 2020 Dodge Charger SXT is also available with all-wheel-drive and in the V6/AWD models, the TorqueFlite 850RE is the chosen gearbox, working with a standard 3.08 rear gear. The 850RE is essentially the same transmission as the ZF 8HP50, but the 850RE is built by FCA. The individual transmission gear ratios are as follows.

1st 4.71
2nd 3.14
3rd 2.10
4th 1.67
5th 1.29
6th 1.00
7th 0.84
8th 0.67
Reverse 3.30
Final Drive Ratio 3.08

2020 Dodge Charger Hemi Transmissions
The 2020 Dodge Charger is available with three different Hemi V8 engines; the 5.7-liter mill from the R/T and R/T Daytona, the 6.4-liter V8 from the R/T Scat Pack and 392 Daytona and the supercharged 6.2-liter engine in the Hellcat models.

The 5.7- and 6.4-liter Hemi engines share the TorqueFlite ZF 8HP70 8-speed automatic transmission, so the vast majority of Chargers sold come with this gearbox. In 5.7-liter models, a 2.62 rear gear set is standard while an asymmetric limited-slip 3.09 gear set is standard with those Chargers packing the 6.4-liter Hemi. Individual transmission gear ratios are as follows.

1st 4.71
2nd 3.14
3rd 2.10
4th 1.67
5th 1.29
6th 1.00
7th 0.84
8th 0.67
Reverse 3.32

Finally, the 6.2-liter Hemi in the SRT Hellcat and limited edition 50th Anniversary Edition Daytona comes mated to the TorqueFlite ZF 8HP90 automatic transmission. The asymmetric limited-slip 2.62 rear gear ratio is standard and unlike the Challenger, the 3.09 is not offered as an option with the muscular sedan. The gear ratios for the Hellcat transmission are as follows.

1st 4.71
2nd 3.14
3rd 2.10
4th 1.67
5th 1.29
6th 1.00
7th 0.84
8th 0.67
Reverse 3.32
