Mercedes TCU Programming & Cloning – Plug & Play with No Hassle

At Prestige Performance Group, based in Newtownards, Northern Ireland, we specialise in advanced Mercedes-Benz diagnostics and control unit programming — including expert Transmission Control Unit (TCU) cloning and replacement services.

Whether you're a local customer needing on-site support or a trade client posting your TCU from across the UK, we’ve got you covered.

⚙️ What Is a TCU and Why Does It Matter?

The Transmission Control Unit (TCU) is the electronic brain that manages your automatic gearbox. It works with your engine ECU, ABS, and other modules to ensure smooth gear changes and optimal performance.

When it fails or isn't coded correctly after replacement, you may experience:

• ❌ Gearbox stuck in one gear

• ❌ Jerky or delayed shifts

• ❌ Dashboard warning: “Transmission Visit Workshop”

• ❌ Non-start conditions after gearbox or TCU swap

• ❌ VIN mismatch or coding errors

• ❌ No communication with diagnostics tools

💸 Why Dealer Replacement Can Be Expensive

A main dealer will typically charge:

• New TCU unit: £800–£1,500

• Labour & SCN coding: £250–£500

• 🔧 Total: £1,000–£2,000+

Dealers also usually won’t install used TCUs due to security protocols, leaving you with limited and costly options.
