Spoke to someone who suggested it is a hydraulic problem. Was it fine before the valve body etc was changed? If so, then almost certainly a mechanical issue you can't tune out.

Also has it been tuned? They suggested that if so, return it to stock as most rebuild kits are for a stock tune.

it hasn't been tuned at all.. doesn't do it in manual mode or when its cold... when you have the scan tool on you can see in active data that it selects 2nd then jumps between 1st thats why i'm thinking its software..... and only light throttle it does it stick your boot in and its perfect..... its had the early oil pump fitted and running the 4l60e pressure reg
