A family-owned and operated business with a stellar reputation for specializing exclusively in GM vehicles. They are known for their technical expertise, particularly with complex diesel and transmission systems, and for providing a dealership-level of knowledge with independent shop pricing and personal service.
While "Transmission" is in their name, this well-established shop offers comprehensive automotive care with a recognized specialty in 4WD, AWD, and truck services. They are a go-to for Allison transmission rebuilds and heavy-duty suspension work on trucks used for towing and hauling.
This shop explicitly markets itself as an auto *and truck* repair center, making it a strong candidate for owners of GMC Sierras, Sierras HD, and Yukon XLs. They handle a wide range of services from routine EcoTec maintenance to more complex drivability and electrical issues on heavy-duty platforms.
** The GMC repair market in the immediate Highland Lakes area is limited, with no dedicated GMC-specific specialists located directly within the town's small commercial footprint. Therefore, residents typically rely on reputable service providers in neighboring communities such as Vernon, Sussex, and Augusta. The competition is moderate, characterized by a few high-quality, long-standing independent shops that have built trust through generations of local service. The average quality is high among these established players, as they survive on reputation in a close-knit area. Pricing is typically 20-30% lower than dealerships (like the ones in Morristown or Wayne) but reflects the specialized expertise and overhead of independent businesses. For highly specific issues, particularly with Denali electronics or complex Duramax emissions systems, customers may still consider the dealer for the absolute latest diagnostic software, though the shops listed above are well-equipped for the vast majority of repairs and services.

Common questions about gmc repair services in Highland Lakes, NJ
Due to our local climate with cold winters and road salt, common repairs include brake system corrosion, suspension wear from uneven rural roads, and battery failures. For GMC trucks and SUVs specifically, issues with the 4WD/AWD systems and exhaust components are also frequent visits to local shops.
Look for shops in Vernon, West Milford, or Sparta that are ASE-certified and have specific GMC/GM diagnostic tooling. Check for online reviews and ask if they specialize in domestic trucks and SUVs, as many local shops have expertise suited for the popular GMC models in our area.
Labor rates in Sussex County are typically competitive, but parts costs for GMC trucks and SUVs can be significant. Getting multiple estimates from local shops is advised, as pricing can vary between a dedicated GMC specialist and a general repair shop.
Seek immediate local diagnostics if the light is flashing, indicating a severe misfire that could damage the catalytic converter, especially important given our hilly terrain. For a steady light, a reputable local shop can read the code and advise if it's a critical issue like an oxygen sensor, common in older GMCs, before a long commute.
The hilly, wooded terrain and seasonal potholes necessitate more frequent suspension and alignment checks. Also, given the heavy snowfall, ensuring the 4WD system is serviced and brakes are in top condition before winter is crucial for safety on local roads like 515 and Echo Lake Road.
