99 Avenger, 2.5, 4speed automatic: Car started shifting bad then stuck in 2nd rear. Read in might be input speed sensor. Went to replace it and found that mice had chewed through the 2 wires leading to the input sensor. I correctly spliced the wires together, replaced the input sensor. Car drives great for 1/2 mile the it bumps, reeves up then sticks in 2nd gear. Check eng light comes on. Codes po700, p0733, p0734. Help
