The only thing I could think of would be either it is starting out in second (we can test in a min), or the torque converter is locking up.

Lets do some testing to see if you are starting out in second gear. First put your truck in second gear and start to pull off to around 5 mph or so. Make sure your truck does not shift out of what ever gear you are in. If it does stop and restart. Next were going to yank the lever down to first gear. The truck should still be in first gear at 5 mph (mine doesn't shift till 10mph) so you should not hear a shift and nothing should change. if it does, it means your trans is starting out in the wrong gear.

lets test to see if the torque converter is locking early. to do this test I want you to put it in drive and start giving her some gas down the road. if she pulls off slowly like you said, this is good because you will notice it more. If she is going slowly and still holding that slow first gear, with your foot still on the gas i want you to push on the brake and hold for a few seconds. Im not saying slam on them or anything, but rather just enough for your brake lights to light up. If your rpms jump 200 or so rpm when you did this, then your torque converter is locking early.

I am no trans expert so take this advise lightly, but those would be my two guesses as to why your truck would take off slowly in drive. As to why it is doing it in drive and not any other time, you honestly got me. If your really concerned about it, i would take it back to the place who rebuilt as you are hopefully still under warranty with 10k and ask for advise.

I hear ya. Yeah I mean there are a couple sensors in the transmission but I just know if I was in the same boat as you, I would perform those two tests on my truck to help narrow it down a bit so you would know what specifically is happening. We did have a tranny expert on here a while back but I haven't seen him around in a while. (username MonteC).

Especially with an F-ed up tranny lol, If the work was recent I would make them haul it up. Hopefully its still under waranty.

maybe someone removed the check valve?....if so it would take ten secs or so in gear to fill the torque converter with fluid I believe ffrom what they say on the threads about it....

after you drive about 50 feet, or if you have it in gear or neutral for a few seconds after you start it then the torque converter will stay full until it sits for a few hours or more again. mine is one of the trucks that has the drain back issue.
it sounds like his truck is starting out in 2nd while in D, all the time.

My truck takes awhile to start moving when I first start it up.Is that the reason?once I am moving its fine but when it sits awhile i have to let it warm up or it will not move.

My trans was rebuilt right before i got it.
