The Chrysler Crossfire gearbox sits at the heart of a sporting coupé launched in the early 2000s and sold for five years. Born from the collaboration between Chrysler and Mercedes, the Crossfire blends American design with German engineering. Reliable and durable, its transmission can nonetheless develop wear-related problems over time. At EDEN BOITES, specialists in exchange gearboxes, we help you spot the warning signs and get your Chrysler Crossfire gearbox sorted.
What makes the Crossfire gearbox special
In 2005, Chrysler offered the Crossfire as both a coupé and a roadster, in three trim levels: Base (or Black), Limited (3.2-litre V6 M112 engine) and SRT-6, whose supercharged V6 M112 produces 335 bhp and 420 Nm of torque.
The Crossfire was available with a 6-speed manual gearbox and a 5-speed automatic gearbox; SRT-6 versions received the automatic transmission only. Both units are of Mercedes origin: the manual is derived from the NSG-370 and the automatic belongs to the 722.6 family. This shared heritage explains the robustness of these transmissions, but also the importance of identifying the exact reference before carrying out any work.
Ten symptoms of a failing Crossfire gearbox
Whether automatic or manual, transmission problems should be taken seriously as soon as they appear: left unchecked, they can damage both the gearbox and the engine. Here are the signs to watch out for:
- difficulty, or even inability, to change gear;
- unusual smells;
- noises from the transmission when stationary;
- gears jumping whilst driving;
- grinding from the gearbox;
- oil patches on the ground, indicating a transmission oil leak;
- a warning light coming on;
- juddering when changing gear;
- squealing from the transmission;
- sluggish or unresponsive gear changes.
How to fix Crossfire gearbox faults
As soon as a worrying sign appears, consult a specialist: leaving the problem unaddressed can be dangerous. Initially, it may not be necessary to replace the entire transmission — sometimes a simple oil change or a seal replacement is all that is needed.
The mechanic will first carry out a mechanical diagnostic to assess the level of wear, the extent of the damage and its cause, using specialist equipment or by stripping the gearbox down. Depending on the fault, they will replace the defective parts, carry out an oil change, or replace the gearbox entirely, cleaning everything before reassembly. For an automatic gearbox, a supplementary electronic diagnostic checks that no error codes remain.
When wear is too advanced, replacement becomes the safest solution. An exchange gearbox — reconditioned and tested — offers a lasting repair: browse our exchange gearboxes.
