When slowing down, the transmission (at about 5-10 mph) downshifts sharply into 1st. Doesn't make a noise, but you can feel it.

Sounds like your bands may be wearing or your shift solenoid may be burning out.

Once I seen that the brakes was locking up at lower speeds causing it to down shift pretty harshly.

Try some lucas transmission fix, after draining out a quart of tranny fluid, see if that helps it.

If not bring it to a transmission shop.
