The Cadillac SRX has used two different automatic transmissions across its two generations. Early models rely on a 5-speed automatic, while later models use a 6-speed automatic. This reflects GM’s transmission updates over the SRX’s production life from 2004 to 2016.
Two generations, two transmissions
Here is a quick breakdown of which generation used which transmission:
- First-generation SRX (2004–2009): 5-speed automatic transmission.
- Second-generation SRX (2010–2016): 6-speed automatic transmission.
In addition to the base transmissions, the SRX's drive system (rear-wheel drive bias or all-wheel drive) does not change the number of gears, but AWD versions use a center differential/transfer arrangement that works with the same 5- or 6-speed automatics depending on generation.
Details by generation
The transmission type aligns with the SRX’s generation and engine options:
- First generation (2004–2009): 5-speed automatic. This generation offered the Northstar 4.6L V8 and a V6 option, both paired with a 5-speed automatic transmission.
- Second generation (2010–2016): 6-speed automatic. This generation moved to a 6-speed automatic with updated engines such as the 3.0L V6 and 3.6L V6, improving refinement and efficiency.
Note: Specific transmission configurations can vary by model year and engine, but the overall pattern remains: a 5-speed automatic for the first-generation SRX and a 6-speed automatic for the second-generation SRX. If you’re buying used, verify the exact transmission designation in the vehicle’s VIN or owner’s manual, as there were few exceptions to this trend.
What to check when buying used
When evaluating a used SRX, check for smooth shifting, no slipping, and normal transmission-fluid maintenance records. Common issues in older GM automatics can include rough shifts or delayed engagement, which may indicate fluid service needs or, in some cases, more substantial repairs.
Summary: The Cadillac SRX’s transmission evolved from a 5-speed automatic in its first generation (2004–2009) to a 6-speed automatic in its second generation (2010–2016). This shift mirrors GM’s broader move to 6-speed automatics across its SUVs during that era.
