JA: Sometimes things that you think will be really complicated end up being easy to fix with a Chevy. The Chevy Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: Also transmission will shift hard when starting from standing stop
JA: Are you hoping to fix this yourself?
Customer: No
JA: OK! The Chevy Mechanic will help you with the diagnostics so you are sure to get this fixed right. Is there anything else the Chevy Mechanic should be aware of about your Chevy?
Customer: Several steps have been taken. 106K. maintenance was performed. Transmission fluid disappeared. Mechanic advised me the gasket between the transmission and the box behind was damaged. It was replaced A valve was replaced, I believe the tcc pwm, but I am not sure

to test them you push the brakes while giving it throttle and you can hear a definate increase of rpm, sounds like a up shift, or let off throttle and get back on, the RPM's will be raised but right away drop (TC locking up).
