High rpms no speed

[penalty333]

Ok i just bought a 3.3 to replace my 2.5r and i installed it and started break in process i got up to tank four and when i gave it full throttle the engine rpms just went up like crazy but the truck was barely moving i stopped and I'm waiting for an answer so i dont ruin my new engine. Also when i start it the truck rolls forward how can i stop this. I would really like an answer soon thanks its a tmaxx

If it rolls forward the idle is too high or the springs are weak in your clutch bell.
If it revs and barely moves your slipper clutch needs to be tightened. If that doesn't help you have a broken pin somewhere in your drive train.

+1 on the slipper adjustment, I like it that when I pull the throttle, it moves immediately! No "spool" up time.
