Maintenance and repair of IVECO 35S gearboxes

To help you maintain your Iveco 35S, EDEN BOITES provides a complete gearbox maintenance guide.

How do I keep my IVECO 35S gearbox?

Understanding how it works

A vehicle's gearbox transmits engine power to the drive wheels. It adapts engine torque to the needs of the drive shaft.

This transmission can be either front-wheel drive or rear-wheel drive, as on theIveco 35S11 V12 3.5T, or all-wheel drive.

In terms of gearbox type, the first distinction is between a manual gearbox: the driver controls gear changes using the gearshift and clutch pedal. A five-speed gearbox is available for theIveco CHASSIS DOUBLE CABINE 3.5T 35S14D EMPAT. 3750 and with six gears for theIveco DAILY PLUS CHASSIS-CABINE 4X2 35S15/2.3/P EMPAT. 3000 BV6. The automatic gearbox can be found on models such as theIveco V 2.3 33S11 AGILE V12 H2 3250L.

Taking care of your box 

Iveco Daily 35S gearbox failure prevention starts with flexible driving. A manual gearbox requires special attention: the risk of damage is greater, since the driver is the one who calls on the gearbox to change gears. Here are a few tips on how to keep your manual gearbox: 

• Do not rest your hand on the gearshift lever as this may cause premature wear of the transmission forks;
• Use the neutral position when the vehicle is stopped at a traffic light or in heavy traffic;
• Do not leave your foot on the clutch, even with light pressure, as this may cause rapid damage to the clutch release bearing;
• Don't rush through gear changes to give the synchronizers time to perform their liaison role;
• Avoid using the engine brake too often : note that it costs less to replace brake linings than an engine, transmission or clutch disc.

For automatic gearboxes, remember that it is absolutely crucial to bring your vehicleto a complete stop before engaging Park or reverse.

Watch for signs of failure

One of the first signs of failure in your Iveco Daily 35S gearbox is the appearance of unusual noises such as whistling, crackling or rubbing. Resistance when operating the gearshift lever may indicate a mechanical problem, such as incorrectly adjusted control cables or worn parts.

The sensation of gears jumping or disengaging may indicate a problem with the gearbox's internal locks. Finally, a drop in your vehicle's overall performance should also alert you.

Check transmission oil level

One of the most common reasons for gearbox malfunction is a lack of transmission oil, sometimes caused by a visible leak under the engine. A regular check of the oil level and appearance will help determine whether or not an oil change is necessary.

The oil change is more frequent for an automatic gearbox, since it is recommended every 60,000 kilometers by the automakers. It is often advisable to change the oil in a manual gearbox after 250,000 kilometers.
