Check the drain pump (attached to front of motor) to be sure there's nothing stuck in there, the pump impeller should turn freely both direction's (use a socket drive extension to insert on the back side of pump to rotate impeller). Also, check the tub to pump hose (fat short hose) to be sure nothing is stuck in there.
Manually rotate the Basket (grab the upper metal rim) to see if it will turn either CW or CCW. If it doesn't rotate in one direction, you may have some fabric items stuck between the basket and outer tub which can cause drain and spin issues.
With Motor removed, you can manually turn the motor coupler attached to the front side of Gearcase/Transmission. The Basket & Clutch (round silver metal object above transmission) should rotate when turning either CW or CCW direction. While the Basket rotates, the Agitator should not be rotating in the back and forth direction (if it does then transmission is bad). Most of the Water should drain before it starts to spin (if it doesn't then possibly related to the neutral drain kit that fits inside transmission). You could bypass the lid switch (jump the L1 & Neutral Wire located on wiring diagram inside the control panel) so you can view the drain/spin cycle with lid open.
