GM 6L45 / 6L50 / 6L80 / 6L90 TCM Clone Service | Plug & Play Transmission Module Programming

Replace a failed GM transmission control module without dealing with unnecessary programming headaches.

LaCorte Automotive's 6L45 / 6L50 / 6L80 / 6L90 TCM Cloning Service transfers the required programming and vehicle-specific data from your original transmission control module to a compatible replacement unit.

How It Works

1. Purchase the service.
2. Mail us your original TCM and compatible replacement TCM.
3. We read and transfer the necessary data from the original module.
4. The cloned replacement module is tested and returned to you.
5. Install the replacement unit back into the vehicle.

Why Clone the Original TCM?

Installing a used replacement transmission module can result in programming or compatibility issues because the replacement module contains data from its previous vehicle.

Cloning allows us to transfer the required information from your original module to the replacement, making the replacement unit match your vehicle as closely as possible.

What You Need to Send

Standard Clone Service:

• Original TCM
• Compatible replacement TCM

If you do not already have a replacement module, contact us before ordering. We may be able to supply a compatible replacement depending on availability.

Important Compatibility Information

The replacement TCM must be compatible with your original unit. Matching hardware and part numbers are strongly recommended.

If you're unsure whether your replacement module will work, send us clear pictures of the labels on both modules before shipping and we can help verify compatibility.

Failed or Damaged Original Modules

In many cases, data can still be recovered from a module that no longer operates correctly in the vehicle. However, severe electrical, water, or physical damage can make the original data unreadable.

If the original TCM cannot be read, we will contact you before proceeding with any alternative programming options.

Professional Mail-In Service

Every module is handled using professional automotive programming equipment and the original data is preserved whenever possible.

This listing is for programming/cloning service only unless a replacement TCM is specifically included as an option.
