Improved Car Automatic Transmission

A plugin that makes the automatic gearbox behave like a modern car's automatic transmission instead of a truck's. Originally written for car mods, but applies to every vehicle.

Features

• Realistic Dual-Clutch (DSG) Simulation: Independent shafts (K1 odd / K2 even) with seamless, zero-torque-interruption crossover shifts. Dynamic shift physics with authentic shift punch, automatic rev-matching downshifts, and two-stage same-shaft skip-shifting.
• Realistic Flywheel Physics: Car engine inertia with rapid, responsive free-revving in neutral, authentic internal friction, rapid rev-drop off-throttle, and a redline fuel-cut limiter with recovery hysteresis.
• Adaptive Shift Logic: Smart shift windows that dynamically scale shift points based on throttle position, pedal application speed, and road demand. Holds gears during rapid throttle lift-off in corners, prevents overdrive upshifts while coasting, and locks lower gears on declines for engine braking.
• Drive Modes & In-Game UI: Four selectable profiles (Normal, Sport, Comfort) via hotkey (default F8) with on-screen HUD notifications. In-game configuration window (F9) to customize shift maps, delays, and flywheel mass in realtime. Live telemetry dashboard for active gears, G-forces, K1/K2 clutch pressure, propshaft torque, and active shift phases.

Installation

Copy the "bin" folder from the archive into your game installation directory so the DLL ends up at bin/win_x64/plugins/car_automatic_transmission.dll. Create the "plugins" folder if it does not exist. After launching the game once, the folder car_automatic_transmission containing car_automatic_transmission.cfg will appear next to the DLL.

Notes

Single player only. Do not use with TruckersMP or Convoy. The DLL writes to the game's code in memory, which some antivirus scanners may flag. It is unsigned, but the full source code is included so you can review and build it yourself.
