ECM / PCM / TCM Modules in Houston — VIN-Matched, Local
Engine, powertrain and transmission control modules matched to your VIN — from a real Houston yard, not an out-of-state mail-order shop.

When an ECM, PCM or TCM fails, the car is dead in the water — and most module sellers online are out-of-state mail-order shops, so you wait on cross-country shipping before you even know if the part is right. Ultra Auto Parts TX sources engine, powertrain, transmission and body control modules through our nationwide salvage network, matched to your exact VIN, with local Houston pickup and delivery. Here's how module replacement actually works and how to buy the right one the first time.
Why the VIN matters more than the part number
Modules are the most fitment-sensitive parts on a vehicle. The same year/make/model can use different calibrations by engine, transmission and emissions package — and a module that physically plugs in can still refuse to start the car if the software doesn't match. We decode your 17-character VIN and match the module by the exact application, not just the part number stamped on the case.
Programming: what really happens after you buy
Depending on the vehicle, a replacement module either needs to be flashed to your VIN before install, programmed at the vehicle with a J2534 pass-thru or dealer tool, or needs a security/relearn procedure (crank relearn, immobilizer sync, throttle relearn). We tell you up front which case applies to your vehicle so your installer isn't surprised — no 'plug and pray'.
Local vs mail-order
Buying a module from an out-of-state web shop means shipping days each direction — and if the calibration is wrong, you do it all again. Buying local in the Houston area means you talk to a real yard, the module is VIN-matched before it moves, and returns cost 0% restocking — ever. We're at 5041 Spencer Hwy in Pasadena, and we deliver locally with our own drivers.
What we cover
ECM/PCM (engine & powertrain), TCM (transmission), BCM (body), fuel pump control modules and transfer case control modules — used, tested units sourced through our nationwide network for domestic and import applications, with our Standard 6-month warranty. If your module failure turns out to be a deeper engine or transmission problem, we're drivetrain specialists first — we diagnose honestly and quote the real fix.
