Hello everyone, my 2005 Corvette automatic is giving me problems. I was driving my car and when I get to about 20-30mph the motor begins to rev but no forward movement unless I let off the gas and rpms fall to about 2000 then hit the gas again, or by accelerating which the rpms begin to climb no forward movement and then will shift after 2-3 seconds but much more aggressively. This happens again around 50-60mph.

I have searched google, looked up problems with the 4l65e transmission, searched youtube but I can't find whats causing this problem. Has anyone ever had this problem? I did see many GM forums post about this same problem but to my luck I didn't see anyone state what fixed the issue. All help is deeply appreciated. Im located in Maryland if anyone knows a shop that could help fix this problem. Thanks

I have a 2005 same tranny. Its had a tune and shifts firm no issues with drive-ability but its got a leak and was quoted 2k to fix the leak which involves removing the trans and differential. Good luck
