Unveiled at the Turin Motor Show in November 1984 and produced until 2014, the Lancia Thema is a saloon that won admirers for its elegant styling and performance. Keeping its transmission in good order is essential to preserve those qualities and extend its working life. Whether you're an experienced mechanic or simply an enthusiast, this guide will help you look after the gearbox on your Lancia Thema.
Lancia Thema Gearbox: Key Specifications
Lancia produced the Thema across three distinct generations:
- the Lancia Thema (1984–1995), available in petrol and diesel, launched with either a 5-speed manual gearbox or a 3-speed automatic gearbox;
- the Lancia Thema SW (1987–1995), the estate variant of the range;
- the Lancia Thema 2 (2012–2014), derived from the Chrysler 300, offered in petrol and diesel with automatic transmissions only.
Early Warning Signs of a Problem
A Thema that feels less responsive, or unusual noises coming from the transmission, can signal an impending fault. The symptoms vary depending on the type of gearbox.
On a Manual Transmission
- Abnormal noises: grinding, clunking or vibrations when changing gear;
- Difficulty selecting gears: catching, inability to engage certain gears, or a trembling gear lever;
- Clutch pedal irregularities: sponginess, excessive travel or unusual vibration.
On an Automatic Transmission
- Dull thuds or clunking noises, particularly at low speed;
- Juddering, hesitation or a slipping sensation during gear changes;
- Warning lights appearing on the dashboard;
- an unusual smell coming from the transmission.
Diagnosing a Fault on the Lancia Thema
When these signs appear, a methodical approach helps pinpoint the problem. Observe and note any irregularities: the type of noise, when it occurs, and any difficulties experienced. Inspect the gearbox for oil leaks or signs of friction, and check the oil level in accordance with the specifications for your model. A road test will then allow you to assess how the transmission behaves in different conditions. If in doubt, a qualified mechanic has the tools needed for a thorough inspection. Our complete gearbox repair guide covers each of these steps in detail.

Gearbox repair is a complex job that demands in-depth knowledge, specialist tools and a suitable working environment.
