Hauling heavy loads puts extra strain on your truck’s transmission. Did you know that nearly 90% of transmission failures are caused by overheating, poor maintenance, or not changing the fluid regularly? Watch for these five signs your truck may need transmission repair: Difficulty shifting gears, burning smells from the engine, slipping gears with sudden power loss, leaking fluid under your truck, or shaking and grinding noises while driving. Each of these symptoms can mean your transmission is wearing out and needs attention to avoid more costly repairs. Don’t wait until a small issue becomes a big problem, take care of your truck and stay safe on the road. For more tips or to schedule service, visit our website today.

The customer noticed that the converter was shuddering, so we looked at it more closely. The problem turned out to be a worn-out pressure regulator valve in the 6L80E. These 6L80E and 6L90E transmissions never make for a quick and easy repair.

Sometimes, components may appear to be in good condition, but upon closer examination, we find they are actually worn out. Our goal is to ensure quality and perfection in our work, and we appreciate your patience as we strive to deliver the best results.
