Hi, my transmission is a 4L65e with a 4600rpm stall converter. The problem is; I do a big burnout to warm up the tyres, then when I stage and go to take off, I dont have 1st gear. The car will take off from 3rd, then after 1-2 seconds it kicks back into 2nd and continues nicely. When this happens, the speedo stops working everytime.

If I do a smaller burnout it's usually ok. Any ideas? There are no lights or warnings from the car. I'm thinking maybe the p0068 tps vs airflow values need to be maxed out.
Anyone experienced this before? Thanks
