Chevrolet Equinox engine RPM revs during gear shifts at 40 mph after transmission fluid flush on Chevrolet Equinox

Some Chevrolet Equinox owners report experiencing engine RPM revving during gear shifts at 40 mph after a transmission fluid flush. This issue may be linked to low transmission fluid levels, which can cause improper gear shifting. Additionally, transmission leaks could lead to difficulties in gear changes, resulting in the engine revving during shifts. Some owners also report transmission slipping, where the engine revs without the expected acceleration. Furthermore, unusual noises such as grinding, humming, or whining during shifts may indicate internal transmission problems that require repair or replacement. It is recommended that owners check the transmission fluid level, inspect for leaks, and listen for any unusual sounds. If the problem persists, consulting a mechanic or dealership for a thorough diagnosis and potential repairs is advisable.
