Short answer: A 2007 Chevy Colorado could be equipped with either a five‑speed manual or a four‑speed automatic transmission for most gasoline engines, while diesel variants (2.8L Duramax) offered a six‑speed manual or a four‑speed automatic, depending on the configuration.
In more detail, the 2007 Colorado spanned multiple engines and trims, which meant multiple transmission choices. Buyers could select between manual and automatic transmissions, with the diesel version adding a taller six‑speed manual option in some configurations. The exact pairing depended on the engine, cab configuration, drive type (2WD or 4x4), and market.
Gasoline-engine Colorado transmissions
The following transmission options applied to gasoline-powered Colorado models, depending on trim and market.
- Five‑speed manual transmission
- Four‑speed automatic transmission
Gasoline models largely offered a standard manual option for drivers who preferred greater control, with the automatic becoming more common on higher trims and for daily driving convenience.
Diesel-powered Colorado transmissions (2.8L Duramax)
Diesel variants of the 2007 Colorado offered a different pairing, reflecting the torque characteristics of the Duramax engine.
- Six‑speed manual transmission
- Four‑speed automatic transmission
Diesel configurations typically favored the manual option for better control during towing and hauling, while the automatic provided easier operation for everyday use.
Summary
In summary, the 2007 Chevy Colorado offered two primary transmission families across its engines: gasoline models with a five‑speed manual or four‑speed automatic, and diesel (2.8L Duramax) models with a six‑speed manual or four‑speed automatic. Availability varied by engine, trim, and market, so the exact pairing for any given vehicle could differ.
