About GCP
More than a repair shop
GCP combines a heavy duty shop, an advanced diagnostics and programming center, a performance shop and a systems integration specialist — so a project that needs mechanics, electronics and software does not have to travel between three businesses to get finished.
GCP in New Hyde Park
Built around trucks, diagnostics and technology
More than a repair shop
Engineering-level solutions for trucks and heavy duty equipment
Our goal is not simply to replace parts. It is to correctly identify the cause of each problem and deliver a complete solution — from a conventional mechanical repair to advanced programming, wiring and electronic integration projects.
GCP aims to be the place customers, transport companies and other repair shops come to when a problem needs mechanics, electronics and programming working together.
Diagnose. Repair. Program. Integrate. Perform.
What makes GCP different
- MechanicalRepair and maintenance.
- DiagnosticsAdvanced diagnostics to find the real cause of the problem.
- ProgrammingProgramming and configuration of electronic modules.
- PerformanceTuning and optimization of how the vehicle runs.
- IntegrationAdapting engines, transmissions, harnesses, modules and electronic controls.
- TechnologySpecialized tools, software and equipment to solve complex problems.
The Difference
Integration is where projects succeed or fail
Anyone can bolt an engine in. The hard part is everything after: getting the ECM to talk to the transmission, the dash to read correctly, the throttle pedal to be recognized, the sensors to report real values, and the cab switches to control what they're supposed to control.
That's the work we specialize in — and it's why projects that stalled somewhere else end up here.

Configured, programmed and validated until the whole assembly behaves as one system.
Our Approach
Diagnose. Repair. Program. Integrate. Perform.
From a conventional repair to a complete engine conversion, harness modification, module programming or electronic integration — a professional solution from the initial diagnosis to final commissioning.
Evaluation
We listen to the history of the unit, scan every module and map what the vehicle is actually reporting — not just the first code.
Diagnosis
Circuit, sensor, network and bench testing to isolate the true root cause before a single part is ordered.
Solution
Repair, wiring, programming or full integration — with the scope, timeline and cost agreed before we start.
Validation
Parameters set, adaptations run, codes cleared and the unit tested under load until it performs the way it should.
