2020 Chevy Silverado 1500 Transmission Repair in Bowling Green, KY

When you drive a newer style Chevy truck and start feeling that dreaded "Chevy Shimmy," you already know it’s going to be a bad day. These trucks use the 6L80 transmission, and when the torque converter (TC) starts to fail, it often takes the entire transmission down with it. That vibration you’re feeling? That’s the torque converter clutch engaging—and every time it happens, clutch material is breaking down and circulating through the system. As the damage spreads, metal shavings work their way into the transmission, causing even more failures down the line.

Now, every once in a while, someone gets lucky. A customer recently brought us his Silverado with a nasty shudder, reading almost 150 RPM variations on the scanner. That’s a telltale sign that the transmission may have more significant damage beyond just the TC. So, we gave him a heads-up that there was a good chance we’d find more issues once we tore into it. But this customer? He hit the jackpot. His torque converter had just started failing, and to our surprise, there was almost no metal inside the transmission.

So, what did we do? Well, this customer got a deal. We installed a new PR valve, updated the TECHM to disable lockup in lower gears, replaced the filter and TC, and that was it. No internal hard part damage—this transmission was spotless inside. Why hit a customer with unnecessary repairs when their transmission is already in great shape? Instead, we made sure it stayed that way. Now, he’s back on the road, cruising with confidence after getting transmission repairs in Bowling Green, KY.
