New Holland was required by competition authorities to give up Versatile when merging with Case IH. The new large tractors for 2002 were added to the NH lineup simply by painting the Case IH STX Steiger models blue.

The engines used were the company's own 8.3- and 8.9-liter engines as well as Cummins' new 15-liter engine. All engines had a rated speed of 2000 rpm, and peak power was reached at 1850 rpm. Torque increases ranged from 35 to 43%. The smaller engines featured four-valve technology and wastegate turbocharging. The basic transmission was a 24+6 Syncroshift with a 2-speed powershift, which Case IH offered in only one model. However, the more common choice was the 16-speed Fuji Univance full powershift, in which every other gear could be skipped when accelerating if desired. The hydraulics were load-sensing, and the MegaFlow version had a capacity of 340 liters per minute. The cab was newly developed by Case IH and was said to be 23% more spacious than the next most spacious competitor. Controls and instruments were centralized on the right side and the pillar.

In the fall of 2003, the 500-horsepower TJ500 was introduced, which was otherwise similar to the TJ450 model.
