Serving Lewisville, TX — Reliable service, clear pricing, written warranty
Overview
JC Auto Repairs provides professional engine and transmission replacement services for passenger vehicles and light trucks in Lewisville, TX.
Our approach focuses on accurate diagnosis, documented repair plans, and open communication so vehicle owners understand the work, timeframe, and cost before any parts are ordered or labor begins.
If you're experiencing major drivability issues, frequent overheating, loss of power, or repeated transmission failure, replacing the affected assembly may be the most cost-effective and durable solution.
Persistent knocking or loud tapping from the engine at idle or under load.
Repeated transmission slipping, hesitation, or failure to engage gears.
Excessive smoke from the exhaust that does not clear with routine maintenance.
Oil or coolant mixing, indicating internal engine damage.
Check Engine light or transmission warning codes that return after repairs.
Not every symptom requires a full replacement. Our technicians perform a staged assessment that begins with diagnostics, fluid analysis, and test driving to confirm whether repair, rebuild, or replacement provides the best long-term outcome.
Replacement process and what to expect
The process begins with a complete inspection and diagnostic scan. After diagnosis we prepare a written estimate that lists the parts, labor, anticipated timeline, and warranty coverage.
Steps we follow
Initial inspection, diagnostic codes read, and test drive notes documented.
Detailed estimate with labor and parts options — new, remanufactured, or salvage where appropriate.
Scheduling and procurement of parts; we prioritize OEM or high-quality remanufactured components based on the vehicle's needs and the owner's budget.
Qualified technicians remove the old assembly, install the replacement, and conduct system calibrations and fluid flushes as required.
Post-replacement validation: extended test drive, re-scan for codes, and a customer review of the work performed.
We document all work with before-and-after photos and provide clear guidance about post-service care and any break-in procedures for rebuilt or replaced components.
Benefits of professional installation
Proper removal and installation reduce the chance of related failures. When replacement is handled by experienced technicians:
Engine and transmission mounts are checked and replaced if necessary to prevent stress on the new assembly.
All fluids are replaced with the correct specifications and filters are changed to protect the new unit.
Associated systems (cooling, fuel delivery, electronic controls) are verified for compatibility and operation.
This level of attention shortens downtime and lowers the likelihood of repeat visits for the same issue.
Warranty and parts options
We offer warranty options depending on the parts selected. New components usually carry the manufacturer's warranty. Remanufactured units commonly include a limited labor and parts warranty. We review warranty terms with each estimate and provide the warranty in writing.
Transparent pricing and financing
Replacing an engine or transmission is a significant investment. Our written estimates itemize labor hours and parts so you can see where costs are allocated. When financing makes sense, we can discuss options to spread payments.
Frequently asked questions
How long will a replacement take?
Typical turnaround varies with vehicle make and parts availability. Most jobs complete within several business days; for complex or rare parts the timeline may extend and we will communicate expected dates in advance.
