A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Automatic Transmission Control Unit 1267017170 – Iveco Daily
The automatic transmission control unit (TCU) decides when to change gear: based on road speed, engine load and accelerator position it chooses the shift point and controls the solenoid valves in the gearbox. This unit fits: Iveco Daily with 2.3 HPI engine.
Part numbers to compare
- 1267017170 – control unit manufacturer number, on the label: 1 267 017 170
- ZF0501230008 – additional marking
The same numbers should appear on the control unit in your car. The car model alone is not enough – control units differ in software version and configuration.
Signs of a faulty transmission control unit
When the transmission control unit starts to fail, the most common signs are:
- limp mode – driving in one gear only,
- jerky or delayed gear changes,
- a gearbox warning light or message,
- no communication with the control unit in the diagnostic tool.
Before replacing it, check the gearbox oil level and condition, the power supply, earth connections and connectors, and read the fault codes – faulty sensors and solenoid valves cause similar symptoms. After replacement, coding or adaptation with a diagnostic tool may be required.
