The Alfa Romeo 159 gearbox is fitted to an elegant family saloon that arrived in 2005 as the successor to the 156. Sporting by nature, the 159 is not immune to transmission wear over the miles. At EDEN BOITES, specialists in exchange and reconditioned gearboxes, we help you prevent breakdowns and choose the right solution when the time comes.
Preventing Alfa Romeo 159 Gearbox Faults
The best repair is the one you never need. Understanding your 159's transmission and adopting good habits can significantly extend its service life.
Getting to Know the 159's Transmissions
Over its production run, the Alfa 159 was offered with eight engine options — five petrol and three diesel. The petrol units use the JTS combustion system: the 1.9 and 2.2 JTS come with a 6-speed manual gearbox, and the 2.2 JTS can also be paired with the Selespeed automated manual gearbox. The 3.2 JTS V6 is available with four-wheel drive and either a 6-speed manual or the Q-Tronic automatic gearbox. On the diesel side, all versions come with a 6-speed manual gearbox, with the Q-Tronic automatic offered as an option on the 1.9 JTDm 16V and 2.4 JTDm 20V.
Adopting a Smooth Driving Style
A manual gearbox requires more care than an automatic, as gear changes depend entirely on the driver. A few principles help minimise wear:
- press the clutch pedal fully before changing gear, to protect the clutch disc and release bearing;
- release the clutch progressively while easing on the accelerator;
- select the right gear by listening to the engine, ideally around 2,500 rpm;
- use neutral when stationary for extended periods;
- avoid skipping gears when changing down.
On automatic versions, an anticipatory driving style — avoiding harsh braking and sharp acceleration — protects the entire mechanism.
What to Do When the 159's Gearbox Starts to Struggle?
Crunching noises, resistance when changing gear, or a general loss of performance are all warning signs. A few checks can help pinpoint the source of the problem.
Inspecting the Components
Check the gearbox oil level and condition using the dipstick, taking care not to confuse it with the engine dipstick. Inspect the transmission oil seals for leaks, as deterioration causes fluid loss. Once dismantled, the condition of the synchromesh rings, gear teeth, selector forks and gear linkage will indicate how serious the wear is.
Considering an Oil Change
Over time, the oil loses its properties and becomes contaminated with metallic particles that compromise lubrication. An oil change may restore correct operation, provided the fault is not caused by a damaged component.
The EDEN BOITES Solution
When replacement becomes necessary, a brand-new gearbox is not always the most sensible option. The exchange basis allows you to fit a reconditioned, tested gearbox without having to deal with the old unit — we collect it from you. To compare references, browse our gearbox catalogue and the Alfa Romeo range.
Simply identify the reference number stamped on your gearbox and check that it matches the technical details of the product you have chosen. For further guidance, see our general article on repairing your Alfa Romeo gearbox and our guide to the Alfa Romeo GTV gearbox. Our article on the differences between manual and automatic gearboxes can also help you choose the right transmission.
Frequently Asked Questions
Which gearbox does my 159 have?
It depends on the engine: a 6-speed manual on most versions, with the Selespeed automated manual or Q-Tronic automatic available as options. The reference number confirms the exact model.
How often should the gearbox oil be changed?
An automatic gearbox requires more frequent oil changes than a manual. In the event of a fault, an oil change may also be worthwhile to flush out oil contaminated with metallic residue.
Does a smooth driving style really make a difference?
Yes. Careful use of the clutch and gears noticeably reduces gearbox wear and delays the need for major work.
How does the exchange basis work?
You receive a reconditioned gearbox matching your reference, and we collect your old unit at the time of delivery.
