The Italian TL series of New Holland was replaced by the TLA in 2004. Alongside the modernization of its appearance, the biggest change was a new engine. The outdated Ivecos were replaced by EEA’s NEF engines meeting Tier II requirements, which Iveco manufactured for New Holland in Turin. The long-stroke engine had a displacement of 4.5 liters. In the two most powerful models, the engine was turbocharged. Torque increased by 35-37%. However, the figure was enhanced by the engine’s rated speed of 2500 rpm.

The base transmission across the range was a 12+12 gearbox, used since the Fiatagri 90 series, but in Finland, creeping gears were standard, resulting in speeds of 20+12. The long mechanical direction changer lever was still located to the left of the seat. The 24+24 Dual Command version featured a hydraulic direction changer behind the steering wheel and an electric shuttle shift. The shuttle shift buttons were integrated into the main gear lever, as was the button clutch from 2006 onward. The shuttle step was relatively small at 18%. The range shift was still unsynchronized.

Most models offered PTO speeds of 540, 750, 1000, and ground speed PTO. PTO, four-wheel drive, and differential locks were engaged electrically/hydraulically. The front axle had a traditional solid gear lock. Three hydraulic valves were standard. The TL90A and TL100A models also included a trailer brake valve. Lifting capacity was 4450 kg. An electronic lift control was optional. The cab noise level was 75.5 dB. A pillar exhaust pipe was standard. The Dual Command model featured a trip computer. Compared to its predecessor, weights and dimensions had grown noticeably. The listed length, however, now included front weights. Differences between models were reduced, so even the smaller models now had, for example, the same lifting capacity and front axle as the larger ones.
