It is your mechanic's responsibility to pinpoint the problem to the TCM. Solenoids and wiring harness must be tested for possible failure or short. Faulty transmission control modules will ALWAYS illuminate AT light and/or check engine light and produce trouble codes. If you or someone else tried to repair your transmission control module, we can evaluate and possibly repair it, but only in the case that no additional damage was created. Please note, not all modules are repairable.

The repairs made to your moudle are covered by our Limited Lifetime Warranty. Please read full warranty terms and conditions.

After our repairs have been made, your module will be ready to install back on your vehicle, no coding or programming required.
