I bought a new 3.5 L V6 2004 Chrysler Pacifica engine and everything went as expected when installing it. I torqued everything to specs and attached the engine to the transmission. I used a socked and a breaker bar to turn the crankshaft pulley and it only turns around to 350 degree and stops on both sides. (Clockwise and counter clockwise as well). I know that this sounds dumb but does the crankshaft spins freely indefinitely (continuously) or it supposed to stop spinning at 350 degrees when the engine is off? The serpentine belt is still out and the engine is on neutral. (I was thinking that the transmission might be locked?) Any help is very much appreciated. Thank you!
