Common Signs of Transmission Problems

Transmission problems start small but get expensive fast. Here's what to watch for:


  • Shifting Issues: Hard shifts, delayed engagement, or slipping usually mean clutch problems or low fluid. In automatics, these symptoms often point to internal wear or electronic control issues.


  • Noises: Grinding during shifts typically means gear or synchronizer damage. Whining or humming while driving can indicate bearing problems or low fluid.


  • Leaks: Red or brown puddles under your truck mean transmission fluid is escaping. This drops fluid levels and can lead to overheating and damage.


  • Overheating: Burning smells usually mean fluid is breaking down from heat or contamination. Low fluid levels make this worse.



  • Warning Lights: Check engine lights can be triggered by transmission problems, especially in trucks with electronic controls.

    Yes, our experienced technicians are trained to service both manual and automatic transmission systems in heavy-duty vehicles. We have the specialized tools and expertise needed for comprehensive diagnostics and repairs on all transmission types, from clutch systems to electronic controls.

  • Can you perform complete transmission rebuilds on-site?

    While we can handle many transmission repairs on-site, complete rebuilds typically require our shop facilities because of the extensive disassembly and precision work required.
