There could be a few potential issues that could be causing your GMC Envoy XUV to have trouble shifting into third gear. One possible cause could be a malfunctioning transmission solenoid, which is responsible for regulating the flow of transmission fluid and can cause shifting problems if it is not working correctly.
Another possibility could be an issue with the transmission itself, such as worn or damaged gears or a faulty torque converter. The whistling sound you hear could indicate a vacuum leak or a damaged gasket, which could also contribute to shifting problems.
It is also possible that the issue could be related to the vehicle's computer system or wiring, as these components can sometimes malfunction and cause shifting issues.
To determine the exact cause of the problem, it is best to have your vehicle inspected by a qualified mechanic who can diagnose the issue and recommend the necessary repairs.
