Understanding the Basics
The Selespeed transmission is essentially a manual gearbox with automated clutch and gear changes. While this sounds straightforward, it’s a complex system with numerous components that can potentially fail. When working correctly, it should provide smooth, automated shifts with the option of manual control via the paddles or gear lever. The system uses hydraulic pressure generated by an electric pump to operate both the clutch and gear selectors.
Common Warning Signs
Early detection of Selespeed issues can save you from catastrophic failure and eye-watering repair bills. Here are the main things to watch for:
The dreaded “Selespeed System Failure” warning light is often your first indicator of trouble. While this can sometimes be triggered by something as simple as a faulty paddle shifter, it can also indicate more serious underlying issues. Don’t ignore this warning – get it checked immediately.
The Selespeed pump can signal its impending failure through distinctive clicking noises. Any clunking sounds during operation are also serious red flags. Keep an eye out for oil leaks from the Selespeed system, as these can indicate seal failures or other problems that need immediate attention.
Maintenance Essentials
Regular fluid changes are crucial – the system uses a specific type of hydraulic fluid that degrades over time. Many problems stem from owners using incorrect fluid or stretching change intervals too far. The official recommendation is every 2 years or 20,000 miles, whichever comes first. Some specialists recommend more frequent changes in high-mileage cars.
The actuator can be another weak point. If you notice slow or hesitant gear changes, particularly when cold, this could indicate actuator wear. The clutch position sensor can also fail, leading to rough gear changes or failure to select gears properly.
For Potential Buyers
If you’re considering purchasing a 147 Selespeed, here’s what to check during your test drive:
Take the car through all gears, testing both paddle shifters and the gear lever. The transmission should automatically shift down as you slow down – if it doesn’t, there’s a problem. Watch out for random gear changes or slipping, and if the car struggles to get out of any gear (particularly neutral), walk away.
Pay attention to the priming time when you first start the car. While it’s normal for the system to prime before allowing gear selection, excessive priming time can indicate pump issues. If this is combined with any other symptoms, it’s best to look elsewhere.
For Current Owners
Regular maintenance is crucial for Selespeed longevity. Keep an eye on fluid levels and condition, and don’t ignore any unusual behavior from the transmission. Parts can be difficult to source and are often only available through Alfa Romeo, which can make repairs expensive.
Consider joining owners’ forums and finding a specialist familiar with the system. Many problems that dealers might quote thousands to fix can be resolved more economically by experienced independent specialists. Keep detailed records of all maintenance and repairs – this will help both with diagnosis and future resale.
Cold Weather Operation
Selespeed systems can be particularly troublesome in cold weather. The hydraulic fluid thickens, leading to slower operation and increased strain on components. In very cold conditions, let the car warm up for a few minutes before selecting gear, and be gentler with gear changes until everything’s up to temperature.
The Bottom Line
For those in the market for a 147, the manual transmission versions generally offer a more reliable ownership experience. However, if you’re set on a Selespeed, look for examples with documented maintenance history and recent system rebuilds. Current owners should maintain a repair fund and address issues promptly to prevent more serious failures.
