How It Works

1. Purchase the cloning service.
2. Mail us your original TCM and compatible replacement TCM.
3. We read and back up the required data from your original module.
4. The original data is transferred to the replacement TCM.
5. We verify the clone and return both modules to you.

What You Need to Send

Required:

• Original 6T30 / 6T40 / 6T45 / 6T50 TCM
• Compatible replacement/donor TCM

We strongly recommend matching the part number and hardware version of the replacement module to your original whenever possible.

Not sure if your replacement is compatible? Send us clear pictures of the labels or identifying numbers from both units before shipping and we can help verify compatibility.

Original TCM Failed?

A TCM that no longer operates correctly in the vehicle may still contain recoverable programming data. We can attempt to read the original module directly using our programming equipment.

If the original TCM is too severely damaged to retrieve the data necessary for cloning, we will contact you before proceeding.
