TCM Cloning & Programming Service San Antonio

TCM (Transmission Control Module) Cloning & Programming San Antonio

S.A. Locksmith & Security offers professional Transmission Control Module (TCM) cloning and programming in San Antonio, Texas. The TCM controls your automatic transmission’s shift points, torque converter lockup, and adaptive shift strategies. When a TCM fails, your vehicle may be stuck in limp mode, refuse to shift, or throw harsh shifts. We clone your original TCM data to a replacement unit — preserving shift adaptations, VIN, and calibration — so your transmission operates exactly as designed.

What Is TCM Cloning?

The Transmission Control Module (TCM) is the dedicated computer that manages your automatic transmission. It controls shift timing, shift pressure, torque converter clutch engagement, and learns your driving style over time. TCM cloning copies all this data — including adaptive shift tables, solenoid calibrations, and VIN encoding — from your failed unit to a replacement.

Symptoms of TCM failure:

Transmission stuck in limp mode (single gear)
Harsh or delayed shifting
No shifting / transmission slipping
Check engine light with transmission codes (P0700, P0715, P0720)
Torque converter shudder or lockup issues

TCM (Transmission Control Module) Cloning & Programming FAQ

How much does TCM cloning cost?

TCM cloning typically ranges from $300-$700 depending on the transmission type and vehicle. Luxury vehicles with ZF 8HP or dual-clutch transmissions may be higher. Call (210) 348-3677 for a quote.

Can you fix a TCM in limp mode?

Yes. If the TCM has failed internally, we clone the data to a replacement unit and restore full transmission function. If the issue is software-related, we can often reprogram the existing TCM.

What is the difference between TCM and PCM?

A TCM is a standalone transmission controller. A PCM (Powertrain Control Module) combines engine and transmission control in one unit — common in Ford and GM vehicles. We service both.

Do I need to remove the TCM myself?

No. Our mobile technicians handle everything — diagnosis, removal, cloning, reinstallation, and verification — at your location in San Antonio.

Will my transmission relearn after TCM cloning?

A cloned TCM retains all original shift adaptations, so no relearn is needed. The transmission should shift exactly as it did before the failure.
