Why won't Plymouth Voyager Transmission get out of second gear?

If a Plymouth Voyager transmission won't shift out of second gear, it could be due to several issues, such as low Transmission Fluid levels, a faulty transmission control module, or a malfunctioning shift solenoid. Additionally, problems with the throttle position sensor or a clogged filter can affect shifting performance. It's advisable to check the transmission fluid and inspect for any error codes before seeking professional diagnostics and repairs.
