A Heavy Duty 18 Speed Transmission 872236

The development of a range type transmission that splits both the low and the high range has led to some unexpected benefits of simpler and easier shifting.
Employing fewer and simpler parts, an eighteen speed transmission has been developed that allows pre-selection of all splitter shifts and eliminates special shift sequencing that has been required on traditional products.
Spin-off of these techniques can be extended into many other configurations that are popular in the trucking industry.
