When we spin the input shaft from the front of the transmission by hand while looking at the output shaft from the rear tail of the tranny - IT DOES NOT SPIN! We tried on all gears and it doesn't spin - ONLY just a centimeter of movement. Now when i put it on park i shouldn't be able to spin the input shaft... well this tranny you can STILL spin the input shaft by hand in park but output shaft still has the same problem as mention above.
