ok i very recently got a GM Reman tranny. im wondering if this is normal, at half throttle, there a slight pause between the 1-2 shift, 3-4 no pause at all.....at WOT there is no pause at all in 1-2 2-3 etc..... its not a slipping type pause where it revs up, its literally a 1 second pause its like 1st rrr then goes to second

im paranoid abut this tranny, hoping that it isnt flawed, so if this sounds like a error thatll get worse, i need to send this sucker back .

Any insight?
