4r70w problems
I have an 02 ford f150 lariat 4x4 I rebuilt the trans. And now it won't move at all unless u put the petal to tge floor then it will only move about 6 inches.. Any possible ideas of the problem? 1-2 accumulator an piston maybe or a torque converter issue???

There was something wrong, it might have been repairable. Putting the pedal to the floor made sure that the trans needs to come out and get rebuilt. It's toast.

I know you rebuilt it. Then it didn't work and might have been repairable. But now that you floored it and moved it six inches you've wrecked the trans. Take it out and rebuild it again. That kind of abuse will destroy a transmission in a couple seconds. This trans is done.
I realize there is no magic crystal ball here that will pin point the issue for the OP. But, maybe give some pointers to watch for as it comes out again and go through it all over.

There are many problems that could have occurred inside the trans. One that's common when installing the trans is allowing the torque converter to slide forward and disengage the pump. Then when the trans is bolted to the engine without the torque converter properly seated in the pump, the end of the converter crushes the pump.
