MANUAL TRANSMISSION DIAGNOSTICS MARIETTA
We Identify the Real Problem - Not Just the Symptoms
Our Systematic Approach Ensures Accurate Diagnosis and Precise Repairs
Before recommending any manual transmission repair, we conduct a comprehensive diagnostic process that typical shops rush or outsource. Our manual transmission specialists begin with a thorough test drive, assessing clutch engagement, gear selection ease, and synchronizer performance across all shifting points. Next, we perform a detailed mechanical inspection, checking linkage adjustments, clutch hydraulics, and input shaft play.
Finally, we examine your transmission fluid for metal particles and conduct specialized tests to isolate internal issues. This methodical approach means we can often save you from a complete rebuild when a targeted repair will resolve the problem.
