For Applications in Mexico Only
Heavy-Duty Transmissions: High-Performance 14-Speeds, Super Mega 16-Speeds and Super Mega 18-Speeds |
The Multi-Speed transmissions include the High Performance 14-Speeds, Super Mega 16-Speeds and Super Mega 18-Speeds. They were specifically developed to handle heavy-duty hauling and changing application needs. They feature deep starting gear ratios to get you moving with a full-load and an overdrive to enhance top-end speed and fuel economy.
Features:
- No-repeat splitter-shifted design
- Four reverse gears for safe, controlled backing
- Small, manageable steps between gears for performance and flexibility
- Curvic clutch collar design eliminates expensive synchronizers and contributes to greater reliability and longer life
