This is very strange. Me and a friend of mine were driving the car and we parked it in my garage, then we went to home depot and got food. Then we came back and put some new clamps on the boost tube, making sure not to hit or damage any wires or anything.

Then we started the car to test the pipes, car had weird idle. When you give it gas the RPMs drop really fast to normal idle. In park car tries to move forward but gets stopped by it being in park, then when put in R the car doesn't move, then when put in N car moves forward, D,1,2,3 act correctly.

Now when I checked the lines to make sure the pump was working, i found out that nothing was coming back out of the radiator, so i bypassed radiator trotally and i ran the trans lines directly into my trans cooler, bypassing radiator totally, and fluid moves correctly. Now,when I stuck the one end into a bottle to make sure pump works. I ran air into the radiator and chunks came out, seems like pieces from the old trans were in there. I need a new radiator anyway, so i'm not worried about that.

My question is: do you think some old trans pieces got into it and jammed a valve or something? I'm about to flush the whole system and just clean it all out and replace the trans filter. We didin't mess with tuning or anything, this just happened when we came back from about an hour.

When this happened there wasn't any strange smells, sounds or anything just didin't work. Trans temp wasn't overheated or anything either. This is a Stage 4 FLP transmission with 3200 stall. Now only thing original from other trans was the stall, maybe the stall went bad? I have to drop the transmission anyway due to i think my rear main seal is leaking badly, so either way trans comes down. I'm just hopeing it's not something huge.
