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.

A number with the letter P at the start - how do you compare it?
Exactly as it appears on the sticker, character by character. We offer a used, working, original ABS unit for a Jeep with a part number (OEM) and an ATE number.
Jeep ABS unit - P68443423AD / ATE 28.5173-3502.3
A question from a customer: ‘There is a number with the letter P on my part. Is this the one?’ This unit has part number (OEM) P68443423AD and ATE number 28.5173-3502.3. Copy both exactly. We do not state the model; the numbers are what count. The Jeep unit is used, working and original.
OEM and ATE numbers
- P68443423AD - part number (OEM): P68443423AD
- 28517335023 - ATE number: 28.5173-3502.3
In the part number, the letter at the start, the digits and the AD suffix all count. Read the ATE number with its full stops or as a string. If anything differs, write to us rather than guessing. We do not assign roles.
When it is worth looking at this listing
Most often with symptoms like these:
- ESP and ABS faults displayed at the same time,
- no brake assistance during emergency braking,
- the module fails its self-test after the ignition is switched on,
- a persistent pump fault code despite clearing.
A fault that returns after clearing needs a thorough diagnosis. Check the sensors, the wiring harness and the earth. Make sure the battery holds its voltage. Only then order the unit. After fitting, bleed the system and ask about module configuration.
