^ Okay, this is justâŚwrong.
Motorized vehicles must have a transmission system to operate. These come in two main varieties:
- Manual transmissions lower fuel efficiency while cruising and require periodic driving skill checks to avoid stalls and damage to the engine or transmission.
- Automatic transmissions lower acceleration speed & fuel efficiency during acceleration, and are more fragile than manual transmissions, but do not require said skill checks.
Your transmission part must be adequate to the output of your engines, or they will strip, destroying the transmission.
Larger transmission systems are less efficient and require higher and more frequent skill checks to operate. Automatic transmissions become increasingly rare as tolerable power levels increase.
Multiple transmissions can be installed, but require 16 levels of mechanics skill per additional transmission.
Crafting blueprints for ultra efficient automatic continuously variable transmission systems and ultra-high-torque nested-sun-gear transmissions can be found in labs. These require CVD machines to craft and weigh several hundred pounds.
Repairing either variety of transmission requires 16+ mechanics, 8+ fabrication, 8+ bashing weapons, 12 intelligence, and a serrated disk per notch of health. Transmissions must also be provided with transmission fluid. With 8+ cooking, Lard or cooking grease can be substituted for transmission fluid, but reduces the hp of the part and adds a periodic check to see if the part bursts into flame during heavy operation.
