Did you do an air pressure test before putting the valve body on?
Is it a little sluggish on take off?

I just applied air to the ports that make the front and rear band tighting and lossen. If I put it in manual 1st its not sluggish at all if I put in drive it like it slips and doesnt hardle move and whennit does it like the brakes on
