ECU & TCU Programming
Modern vehicles rely on software to control how the engine and transmission operate. When ECU or TCU software becomes corrupted, outdated, or incorrectly configured, it can lead to poor performance, warning lights, or transmission faults even when mechanical components are in good condition.
At Central Gear Transmissions, ECU and TCU programming ensures that control units communicate correctly with the transmission and engine, restoring proper operation after repairs, replacements, or software-related failures.
Programming is often necessary after component replacement or when software issues interfere with normal vehicle operation.
