Replaced TCM and new speed sensor. Code P0700 and P0722 and ABS/Brake lights will still throw. What is it?

Replaced TCM and new speed sensor. Code P0700 and P0722 and ABS/Brake lights will still throw. What is it? Mechanic says the wiring and everything looks great. Is it my ABS brake module? Should I buy that used/new? Should I remove it and send it to get repaired?

How easy is it to locate the module and take it out on my own from a 2001 Volvo S40?

UPDATE: The swapped TCM caused the car to not shift out of 1st gear. Mechanic put the original TCM back in. Now the car cannot get out of 1st gear regardless. I do not know what to do. Do I take the car at a loss and drop this mechanic and suck it up. Run to a Volvo Dealership and pay out the bum just to get the vehicle to work again? I've never been to a dealership but I am prepared to pay money in order to have it running again.

FWIW, the dealer service that I referred to in the other thread cost $411.
I've never taken any of my cars to an outside mechanic or a dealer, but that time I sucked it up.

Looking back, I'm glad I did. To get another 50,000 miles (and counting) out of the car for $411 was worth it to me.
I rolled the dice and won -for a change!

It was the ABS Module in case anyone else has a similar problem. I pulled it out myself and sent it to ModuleMasters. They were quick and did great work. Put it back in and my car is good as new.
