2013 Chevrolet Impala GM TEHCM Solenoid-Pack TCM Clone

2013 Chevrolet Impala — what this service covers

We clone GM TEHCM (Transmission Electro-Hydraulic Control Module) data onto a new or donor solenoid pack so a replacement is effectively plug-and-play. On these transmissions the TCM is not a separate box — it is integrated into the valve body / solenoid pack, so replacing the pack means the module goes with it and the car sees a stranger. We copy your original TEHCM's identity: VIN, calibration, and the learned shift adaptation onto the donor, letting you avoid a dealer SPS (Service Programming System) session. Covers the RWD 6-speeds — 6L45 and 6L50 (Cadillac CTS, ATS, SRX, Camaro V6, Colorado / Canyon) and 6L80 and 6L90 (Silverado and Sierra 1500 through 3500HD, Tahoe, Suburban, Yukon, Yukon XL, Avalanche, Escalade, Express / Savana, Camaro SS, Pontiac G8, Chevrolet SS, Cadillac CTS-V) — and the FWD / AWD 6-speeds — 6T70, 6T75 and 6T80 (Malibu, Impala, Equinox, Terrain, LaCrosse, Regal, Traverse, Acadia, Enclave), roughly 2006-2020 depending on platform. $250 flat. This is module DATA transfer, not a transmission rebuild: the donor solenoid pack must match the family and part number, a shift-adaptation relearn drive cycle is completed at the car after install, and mechanical valve-body wear is a separate repair. A technician verifies the part number by VIN and module label before you ship anything.

What you get

• Your original TEHCM's VIN, calibration, and learned shift-adaptation data cloned onto the donor solenoid-pack module
• Donor part-number and family compatibility verified by VIN and module label before you ship
• Bench read + verify of both units before anything is written
• Bench communication test on a stable, regulated power supply before return
• Clear install notes — including the shift-adaptation relearn drive cycle to complete at the car
• Straight answer up front if your donor is not a compatible match, before you pay

Common 2013 Chevrolet Impala symptoms this fixes

• ✓Harsh, delayed, or no shifts after a solenoid-pack swap on a 6L or 6T six-speed
