TTC Auxiliary Transmissions

Auxiliary transmissions provide maximum versatility for on-/off-highway applications when teamed with a TTC manual transmission. TTC manufactures six models, including two pneumatic (air-shifted), and four manually shifted units. Both air-shifted models feature a single selector with a "no-repeat" shift lever design.

Providing maximum flexibility, all auxiliary transmissions have four speeds, with a .81 overdrive ratio. Standard PTO mountings include: side-mount 6 and 8 bolt openings. A top mount PTO model is also available.

Auxiliary transmissions are used in a wide variety of applications including: drilling-rigs, mining, lumber, and stationary equipment.
