Transmission Overview
Transmission components — shift linkage, seals, gaskets, and hardware — keep the gearbox shifting cleanly and leak-free; worn parts cause hard shifting, jumping out of gear, and leaks. Van Horn Truck Parts carries transmission parts cross-referenced to Eaton Fuller, Meritor, and OEM part numbers.
Match by your transmission make and model and the specific component.
Mechanic & Fitment Specs:
- Match by: Transmission make/model, component
- Cross-references: Eaton Fuller, Meritor, OEM
- Buying tip: Confirm your transmission model/ratio before ordering internal parts
