v1.4 Real Mack Maxitorque ES T300 Series Transmissions for SCS Mack Anthem

Mack Maxitorque ES T300 series transmissions for the SCS Mack Anthem and Redd's Mack CHU613.

In addition to Mack mDRIVE, Mack mDRIVE HD, Allison RDS, and Eaton-Fuller transmissions, Mack Anthems are built with Mack Maxitorque ES T300 series manual boxes, featuring triple countershaft design, PTO mounting options for heavy duty and vocational jobs, torque ratings up to 2100 lb. ft., and 9-18 speed options.

Mack is the only truck manufacturer to provide single-source integration of engine, tranmission, and chassis, as well as the only manufacturer of transmissions with lightweight, high strength, one-piece aluminum alloy casting. The compact, triple-shaft design distributes the load among three forged alloy steel shafts. Easy Shift ES design permits smooth transitions in and out of neutral with each shift, while fine pitch sliding clutches permit quicker and smoother shifts. The top gear in all T300 series transmissions is an overdrive, allowing highway speeds at lower driveline torques.

Model numbers take the format [T3/two digits/letter codes/21 if applicable]. T3 designates the modern T300 series. The next two digits indicate the number of forward gears. Subsequent letter codes denote: multispeed reverse (M), low range (LR), and extended output for optional ratio rear power take-off (E). If applicable, 21 indicates 2100 lb. ft rating. Otherwise, 9 speed transmissions are rated for 1700 lb. ft., and 10-18 speed boxes are rated for 1800 lb. ft.
