2001 Corvette - A4 stage II from thunder racing with vig 3200 stall
I was driving down the road at 30-40mph, and gave it a *little* bit of gas to get my speed up and all of a sudden a "check" light came on. I immediately pulled over, and called Horsepower Engineering to help me diagnose. It came up as P0757 which is the 2-3 solonoid for the trans. I reset it, drove down there, and had them test drive the car for 10-15 minutes - it never came on again! I drove it for 20 minutes or so after and it still never came on. It was shifting fine the whole time and even the shop said it was shifting fine. Is this weird???? Has anyone else experienced this? What are your thoughts??

Sound like the code sometimes set with high stall converters, There is actually nothing wrong but the PCM becomes confused due to the stall RPM and thinks the 2-3 shift did not happen even though it did. I would ask your tuner to delete the test for this code as this is a comon fluke code with a high stall converter.

Not always true. When I recieved the light and got P0757 it threw my car into limp mode. I only had two gears available. I had to turn the car off, let it sit, restart and I had all 4 gears back.

That's what happened to me. I couldn't figure out what code to delete so unless I'm on the freeway driving the same speed, above 50 MPH, I just leave the shifter in "D" and haven't had a problem.
