A system that when activated would fully release all of the compressed high-density GN Particles accumulated in the mobile suit, enhancing its mobility and defensive capabilities as well as boosting its output for a limited time. Additionally, the entire mobile suit appears red and afterimages are generated when moving. However, once Trans-Am ends, the mobile suit's performance will drop as all its GN Particles are used up.[ The Gundams deployed by Celestial Being since AD 2312 were designed on the premise of using the Trans-Am System, thus the drop in performance would not be that severe until they could not battle. Furthermore, these Gundams could deactivate the system at any time. As demonstrated by the 00 Raiser, when a machine with a stable Twin Drive System enters Trans-Am mode, it gained a boost in output exceeding Trans-Am's usual three-fold increase, with the amount of GN Particles produced and emitted being far beyond squaring, even surpassing theoretical limits. The amount of GN Particles released by 00 Qan[T] during Trans-Am is said to surpass all other Gundams[15], and this likely remained unchanged for the 00 Qan[T] Full Saber.
