The BMW E46 325i is part of the late-1990s to mid-2000s 3 Series lineup, powered by the M54 2.5-liter engine. This article explains the transmission options offered on that model and what to look for when evaluating one today.
The E46 325i was commonly equipped with either a 5-speed manual or a 5-speed automatic transmission. The manual is a traditional 5-speed unit, while the automatic is typically a ZF-sourced 5-speed with BMW’s Steptronic/manual-shift feature.
Two main transmission options for the E46 325i
Below are the two configurations most buyers encountered, along with brief notes on what each means for driving and maintenance.
- 5-speed manual: A conventional manual gearbox, typically Getrag-supplied, paired with the M54 engine for direct, engaged shifting.
- 5-speed automatic: An automatic gearbox, commonly from ZF (5HP19 family), with BMW’s Steptronic/Steptronic mode to allow manual gear selection when desired.
These two options represent the standard choices for most E46 325i cars, giving buyers a choice between driver involvement and effortless cruising.

Manual transmission specifics
The 5-speed manual was the default for many E46 325i sedans and coupes, aligned with the 2.5-liter M54 engine. Typical maintenance focuses on clutch wear, transmission oil level, and linkage condition; many owners report long service life with regular fluid changes and proper adjustment.
Automatic transmission specifics
The automatic option is usually the ZF 5HP19 family, paired with BMW’s Steptronic function for manual gear selection via the shifter or wheel-mounted controls on some cars. Regular maintenance—especially timely transmission fluid changes with the correct fluid specification—helps prevent common issues such as delayed shifts, torque converter wear, or valve-body problems.
Note: Exact transmission codes can vary by year and market. Always verify the installed unit via VIN or service records for precise documentation.
Common questions and considerations
To address frequent inquiries, here are some clarifications about the E46 325i transmissions.
- Is a 6-speed manual available on the E46 325i? The standard 325i configuration is typically a 5-speed manual or 5-speed automatic; a 6-speed manual is not part of the typical US specification for the 325i, though some markets or future restorations may feature different setups.
- What about the Steptronic feature? Steptronic refers to BMW’s automatic transmission with manual shift mode, allowing the driver to select gears manually without a third pedal.
Conclusion: If you’re evaluating an E46 325i, confirm the exact transmission type and code for maintenance planning and to understand any model-year quirks. VIN decoding or dealer service history can provide the precise specification.
Summary
The E46 325i offered two main transmissions: a 5-speed manual (Getrag) and a 5-speed automatic (ZF 5HP19 family) with Steptronic. Choice affected driving feel and maintenance, and exact codes vary by year and market. Verifying the specific unit is recommended for owners and buyers.
