Cotta Transmission’s TR2205 three gear transfer case is being used in workover rigs, and other custom chassis where standard offerings from other manufacturers just aren’t strong enough.  What sets this gearbox apart from others is that it is designed to handle more load, and keeps going as others run out of steam.

Cotta designed the transfer case for maximum application flexibility. The T-case has mirror symmetry and provides four identical input/output stations.  Each station has a 2.75 x 10 splined shaft, and can be fitted with yokes or flanges.  A disconnect (de-clutch) can be fitted to the I/O stations to provide power interruption.  An optional line of disconnects features SAE pump pad outputs.  A special version of this model can be configured as a transfer case, drop box, PTO, or pump drive. Most options are available for field retrofit without having to return, remove, or disassemble the gearbox.
