Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. There is a big difference between a vacuum leak and a transmission failure. Can you tell me what the vehicle is doing.
Thank you. When you say it would take forever to shift would the engine rev really high before it shifted or did the engine seem to lack power and that would delay the shift?
Thank you. From what you are saying it does sound like the transmission may be failing. If the fluid in the transmission looks perfectly fine and is not dark at all then it may not need a complete transmission. It may be a problem with the pressure due to a valve body problem. A valve body is a much cheaper repair. A faulty air flow sensor or a bad throttle position sensor can also cause this. These would need to be monitored with a scan tool to see what they are reading to determine if they are causing it.
