Auto Repair Services in Fort Worth, TX
Engines, transmissions, brakes, electrical, AC — if your car needs it, we handle it. One shop. No runaround.
Built to Handle Whatever You're Driving
D.M.X Performance is a full-service mechanical shop. We've got the tools, the experience, and the work ethic to fix it right the first time.
Engine Repair & Rebuilds
Misfires, oil leaks, blown head gaskets, or a full rebuild — we diagnose before we recommend and fix the actual problem. We're not guessing with your engine.
Transmission Work
Slipping gears, hard shifts, no reverse, fluid leaks — automatic or manual, we work on transmissions. Repairs and full rebuilds when it comes to that.
More about transmission repair →Brake Jobs
Pads, rotors, calipers, brake lines, master cylinders. We inspect the whole system and tell you exactly what's worn — then fix what needs fixing, nothing more.
More about brake repair →Suspension & Alignment
Pulling to one side, vibrating steering, clunking over bumps — we find the worn part, replace it, and align the wheels so the car drives the way it should.
Electrical Diagnostics
Electrical gremlins are some of the hardest problems to trace. We use professional diagnostic equipment to find the fault and fix the root cause — not just reset the light.
AC & Heating
No cold air, no heat, weak airflow, bad smells — we diagnose and repair the full HVAC system. Recharges, compressors, heater cores, blend doors, all of it.
More about AC & heating repair →Oil Changes
Conventional, synthetic blend, or full synthetic with the right filter for your engine. In and out — no upsells, no waiting around.
Exhaust
Loud exhaust, failed catalytic converter, cracked manifold, exhaust leaks — we repair and replace. Welded right, not patched and hoped for the best.
Check Engine Light
We pull the codes and actually diagnose what triggered them. You'll know exactly what's wrong and what it costs before we touch anything.

Overheating, coolant leaks, water pump, radiator, thermostat, head gaskets — we find where the cooling system is failing and fix it before it takes out your engine.
Pre-Purchase Inspections
Buying a used car? Bring it to us first. We'll go over it top to bottom and give you a straight answer on what it's worth and what it's going to need.
Batteries, Belts & Tires
Battery testing, replacement and terminal cleaning; serpentine, timing and accessory belt inspection and replacement; and flat or spare tire swaps done safely at the shop.
