LOS232037 Transmission Case

The LOS232037 Transmission Case is a factory replacement gearbox housing used in Losi’s 22S platform vehicles (including 22S SCT, 22S ST, and related variants).

It is essentially the plastic left/right transmission case halves that house the internal gears, diff components, and motor mounting structure. If your RC takes a hit and cracks the gearbox or strips the mounting points, this is the part that restores the structural “core” of the drivetrain.

Community Feedback:

RC owners generally view this part as a straightforward “repair-only” component rather than a performance upgrade. It’s commonly replaced after hard impacts that crack the gearbox or strip mounting bosses. Many users note that while the case itself is durable for normal bashing, repeated heavy crashes can stress the mounting points over time. Once replaced, drivetrain alignment and smooth operation are typically restored back to factory condition.
