Automatic / CVT Transmissions

If you’re experiencing the following problems with your American-made, foreign, or European car or truck, it may be your automatic transmission:

Common problems:

  • Burning smell
  • Check engine light
  • Gear slipping
  • Grinding
  • Lack of response
  • Leaking or low fluid
  • Noisy in park or neutral
  • Refuses to go into gear
  • Shaking
  • Shifting delay
  • Transmission light
  • Whining, clunking, or humming

The transmission connects to the engine at the bell housing which contains a torque converter. The torque converter is a fluid coupling that connects the engine to the transmission. The automatic transmission contains planetary gear sets, clutches, and bands to provide different gear ratios. Newer vehicles accomplish this through computer controls. Older vehicles are hydraulically controlled.

CVT transmissions do away with gears entirely. Instead of two gears, there are two pulleys connected by a belt. The engine turns one pulley and the other is connected to the rest of the transmission to the to the wheels. The advantage of the CVT is that the size of the pulleys can change from small to large. It gives infinite gear ratios.

Transmission problems come from many causes like low fluid levels from a leak, overheating, and not changing fluid at recommended intervals. Sometimes it’s simple to determine the problem like design flaws from the manufacturer or not coming to a complete stop when going from reverse to drive.

Other times problems can be more complex like electrical issues, driver abuse, or problems that show up intermittently.

Transmission Diagnosis

An experienced transmission technician properly evaluates the root cause of the problem. He has thorough knowledge of how transmissions operate, and cross-references technical information in service bulletins, repair manuals, and technical repair services.

Troubleshooting | Diagnosis

Using up-to-date computer diagnostic equipment, technicians record any codes found that are stored on the vehicle’s computer. This helps to pinpoint the cause of the problem like a faulty pump, clutch, band, or sensor. Then, the vehicle is taken on a road test and the transmission is monitored.

Following a code scan and road test, an experienced transmission technician evaluates the root cause of the problem be it a solenoid, valve body, or fluid. Then he researches service bulletins, repair manuals, and technical repair services. This accurate diagnosis leads to the correct repair the first time.

Repair | Replacement | Service

Automatic transmissions robotically change gear ratios as the vehicle moves, freeing the driver from having to shift manually. It accomplishes gear changes by hydraulically locking and unlocking a system of planetary gears, clutches, and bands. When something goes wrong, count on Hershey Bros. to give you an accurate diagnosis and fix the problem. Keep your transmission in working order with our services.
