The Cat C-15 was derated on torque when paired with the Allison.
Most Newells in the 07/08 time frame had the 600 HP C-15 with 1850 lb-ft of torque when mated to the Allison. A few had the 625 HP with 1900 lb-ft of torque with the Allison in late 2008 and typical in 2009. With the ZF transmission, the 625 HP C-15's torque was typically 2050 lb-ft throughout the 07/09 time period.
