Is the Suburban's gear shifting violently? Or does it disengage when shifting, causing jerks and delays in movement? The question that is always repeated to us: Why does the GMC gear break suddenly even though the oil has been changed? The reason is often not just the oil alone. In GMC and Suburban, many problems arise from the gear's heat, internal leaks, or using the wrong oil. Over time, leaks start inside the clutches, weakening the torque during shifting. 📌 The problem is that some workshops change the oil and do a temporary programming, the car runs for a few days, and the same problem returns. Inside the workshop, we inspect the entire gear before any judgment: * Computer inspection and programming * Measuring gear pressure * Checking for metal shavings inside the oil pan * Test drive before and after And if it needs overhauling: Original parts + complete work inside the workshop + cleaning the gear cooler + full programming after installation. The warranty is clear and written, and the work includes disassembly, installation, and oil. A radical and guaranteed solution, and if the problem is not solved, the customer is not obligated to pay. Our goal is to fix the real defect before anything else. #GMC #Suburban #
