About the PACCAR TX-18 PRO (heavy-haul AMT)
The PACCAR TX-18 PRO is PACCAR's heavy-haul AMT — 18 forward gears, 2,050 lb-ft torque capacity. Launched 2023 as PACCAR's first heavy-haul-specific AMT (the TX-12 covers regional/highway use). Designed for Kenworth W990, Peterbilt 389, and severe-duty vocational applications where the TX-12's 12 ratios aren't enough. Direct competitor to Eaton Fuller 18-speed manual + Eaton Endurant XD Pro AMT.
