Peace, mercy, and blessings of God be upon you. Does your Avalanche hesitate when shifting? Do you feel a clunk between gears? Or does it suddenly shift late, making the car feel sluggish? The question we are always asked: What is the real cause? Some people change the oil and drive for two days, and the problem returns. Why? Because the issue isn't always just the oil. In Avalanches, we often see: A worn-out transmission control module (TCM) Burnt oil due to heat Internal clutches Or metal shavings in the oil pan causing the jerking and delay. If the problem is neglected, the harsh shifts will increase until the transmission requires a complete overhaul. 📌 We inspect before any work: Computer diagnostics Road test And dropping the oil pan to diagnose the condition of the oil and shavings. If an overhaul or replacement is needed: All work is done in-house Removal and installation Inspection before and after operation With genuine parts and a clear warranty. We don't give a price arbitrarily before knowing the real cause of the fault. A radical and guaranteed solution. And if the problem is not resolved, the customer is not obligated to pay. #Avalanche #Chevrolet #Avalanche_Transmission #Avalanche
