2008 Malibu LT 2.4L 101,000 miles

Last week, I had the MAF sensor replaced due to several codes (most of which were pointing towards the tps - none listed for actual MAF sensor) and the codes cleared afterwards.
This week the following codes remain:

P0102 Mass or Volume Air Flow A Circuit Low Input
P0700 Transmission Control System (Malfunction Indicator Lamp Request)
P2544 Torque Management Request Input Signal "A"
U0073 Control Module Communication Bus Off
U2143 Loss Communication with Steering Angle Sensor SAS

I have put dielectric grease on the MAF sensor connector as well as the BCM (I had already experienced issues with the traction control light coming on and the brake lights remaining engaged at all times GM Chevrolet Malibu Brake Lights On When Brake Pedal Up Problem Repair Guide - Pictures Illustrated Automotive Maintenance Instructions

The pigtail for the MAF sensor has already been ordered (BWD part # PT1338) just in case I need to have this replaced. I have searched through recalls and have found some for the "spacer" that is to be put in by the BCM to rid the traction control issue. However, at this time, my VIN is not included in this or any other recall.

Please help if you have information.
