Maintenance of the Iveco Daily 70c gearbox

What makes the Iveco 70c so special?

As with most Iveco Dailies, the Iveco 70c is equipped with a rear-wheel drive transmission: engine torque is transmitted to both drive wheels at the rear axle.

The manual gearbox is available on all models: six speeds on the 3.0 70C21 3450 and the 3.0 70C21 3750 , for example. The new Iveco Daily Hi-Matic is equipped with an eight-speed automatic gearbox: its technology ensures smooth gear changes in less than 200 milliseconds. It is also found on theIveco 70c18A8P.

How can I prevent my gearbox from breaking down?

Correct gearbox use is the first reflex to adopt in order to preserve the vehicle's transmission system. Regardless of the type of gearbox chosen, the driver must pay particular attention to the surrounding environment and other motorists to anticipate behavior and avoid untimely acceleration or braking.

The Iveco Daily 70c, renowned for its sturdiness, is capable of carrying a heavy load: nevertheless, it is important not to exceed the seven-tonne limit , at the risk of impacting the gearbox and causing it to deteriorate.

How to deal with a faulty 70c gearbox

How do I check the transmission oil level?

Insufficient or deteriorating transmission oil levels prevent effective lubrication of gearbox components, and can lead to premature wear.

To check the oil level, you first need to drive for a few minutes and shift gears one at a time, so that the oil can distribute itself properly in the gearbox. Then open the hood and locate the dipstick, generally located behind the engine compartment. Simply remove the dipstick, wipe it with a clean cloth and reinsert it into its container. 

Finally, you can take it out again to check that the level is as close as possible to the highest mark: depending on the result, you can top up the oil with a funnel to the required quantity.
