lost speedo& 2,3&4th gears,have dtc,s

1997 S420 - ASR,ABS,Brake pad wear lamp,Brake fluid level lamps all on. Lost speedo fuel economy gauge and trans wont shift into 2,3 or 4 th gears.I obtained DTCs as follows:
105 - data link connector
141-o2 bank 1 sencor 2
720- output speed sencor circuit
1605- body acceleration sencor
600- serial link
traction control :
can-traction system communication faulty
can-altitude correction factor from me
can- esp distorted

I checked battery and altinator voltage,good.I pulled the plugs on the wheel speed senders and checked with ohm meter.3 @ 1700 1@ 1800 ohms.
I think the computer is not sending a speed message to the trans,the speedo or the brake system.
Where do I go from here?
