10-Speed RT, RTO and RTX Models

Eaton Fuller 10-speed deep-reduction transmissions have a 5-speed front section, and a 2-speed rear-range section, with a deep reduction gear. The low-low, deep reduction gear is used only when operating under adverse conditions. Low gear in the front section is used only for rough, off-highway conditions, as a starting ratio. The remaining four forward positions are used once in the low range and once in the high range. See Fig. for the shift pattern.

15-Speed RT, RTO, and RTX Models

Eaton Fuller 15-speed deep-reduction transmissions have a 5-speed front section, and a 2-speed rear-range section. They also have five additional deep reduction ratios. The 5-speed front section, and the low and high range sections provide ten evenly and progressively spaced forward speeds. The five deep reduction ratios are also evenly and progressively spaced; however, they do overlap the low range ratios, and should be used only when operating under adverse conditions. See Fig. for the shift patterns.
