Signs of a Bad Transmission

Recognizing the signs of a bad transmission early can help prevent costly repairs. If you notice any of the following symptoms, it may be time to visit Ram Transmissions:

  • Slipping gears – If your car unexpectedly shifts out of gear or struggles to stay in gear, this could indicate a transmission issue.
  • Unusual noises – Grinding, whining, or clunking sounds when shifting gears may signal internal damage.
  • Delayed engagement – If there’s a delay when shifting from park to drive or reverse, it could be due to low transmission fluid or worn-out components.
  • Leaking fluid – A red or brown puddle under your vehicle is a clear sign of a transmission fluid leak.
  • Burning smell – Overheated transmission fluid can cause a burning odor; check it immediately.


If you’re experiencing any of these transmission problems, don’t wait,bring your vehicle to Ram Transmissions for a full inspection and free diagnostic.

Common Transmission Issues

Transmission issues can arise for several reasons, and early detection is key to avoiding major repairs. Some of the most frequent transmission problems we encounter include:

  • Low or dirty transmission fluid – Regular fluid changes help maintain smooth operation and prevent overheating.
  • Worn-out clutch (manual transmissions) – A slipping clutch can make shifting difficult and reduce performance.
  • Torque converter issues – A faulty torque converter can lead to rough shifting and poor acceleration.
  • Faulty solenoids – These electronic components control fluid flow within the transmission. If they fail, shifting can become erratic or sluggish.


Our skilled transmission experts will diagnose the issue for free and recommend the best repair options for your vehicle.
