The 2005 Chrysler 300 uses two automatic transmissions depending on engine: a 4-speed automatic for the 2.7-liter and 3.5-liter V6 engines, and a 5-speed automatic for the 5.7-liter Hemi V8. There was no manual transmission option that year.
Engine and Transmission Options
Overview of which engines paired with which transmissions in the 2005 300 lineup.
Manual transmission availability
Note that Chrysler did not offer a manual transmission in the 2005 300. Some models included a manual-shift mode (AutoStick or similar) within an automatic transmission for simulated manual control, but the gear count remained 4 speeds for the V6s and 5 speeds for the Hemi V8.
Before listing the configurations, here is a quick summary:
- 2.7L V6 — 4-speed automatic transmission
- 3.5L V6 — 4-speed automatic transmission
- 5.7L Hemi V8 — 5-speed automatic transmission
The takeaway: The 2005 Chrysler 300's transmission strategy mapped directly to engine choice, with automatics only and a 4-speed vs 5-speed split.
How to Verify Your Vehicle’s Exact Transmission
If you want to confirm the precise transmission on a specific 2005 300, use these steps.
- Identify your engine by checking the VIN code or window sticker. A 2.7L or 3.5L engine generally indicates a 4-speed automatic; a 5.7L indicates a 5-speed automatic.
- Inspect the transmission for its gear count or model identifier. A 4-speed auto shows four forward gears; a 5-speed auto shows five.
- Consult the owner’s manual or service records, or ask a dealer to pull the exact transmission code from the vehicle’s VIN.
Conclusion: For most 2005 300 models, engine size is the quickest guide to the transmission type, with the Hemi pairing to a 5-speed automatic and the V6s pairing to a 4-speed automatic.
Summary
The 2005 Chrysler 300 uses two automatic transmissions depending on engine: a 4-speed automatic for the 2.7L and 3.5L V6s, and a 5-speed automatic for the 5.7L Hemi V8. No manual transmission was offered. To verify, check the engine code, gear count on the transmission, or consult service records or a dealer.
