Cleaning the sensor may not have fixed problem --also check connections with abs and speed sensors but recheck code and if still maf possible wiring ir sensor failure

The torque converter clutch circuit may be at fault. The best way to determine the problem is to have a scanner/computer to read check engine codes.

No you don't need any transmission work, the parts you listed are part of that. You either have a bad wheel speed sensor or more likey a bad connection at one of the sensors. Sometimes the cables get damaged. The cables are supposed to remain flexible but sometimes the wires inside break. These cables go from the wheel speed sensors and feed information to the ABS system.

The problem is almost certainly NOT the MAF sensor.
This problem can be caused by any one of the following
A faulty or dirty ABS wheel sensor...situated at each one of the 4 hubs
although the ABS light would usually illuminate if one of these sensors is faulty.....but NOT always
A faulty ESP switch The switch may be stuck in the open position, which
WILL illuminate the ESP light and turn OFF your traction control.
Some models are also fitted with a YAW sensor, which detects side slip
while driving. If this goes faulty it will also Illuminate the ESP
light.
This sensor is bolted to the center of the floor panel..under the rear seat.
So as to save time and money..You should have the OBD codes scanned. This will pin-point the problem in minutes.
All the best

SOURCE: mass air flow sensor
The mass airflow sensor is very important...it uses tiny diodes mounted in the flow path of the incoming air to the throttle body in units called CFM. It sends that information to the engine computer and the program calculates the proper amount of fuel needed to mix with the volume of air coming in. It is vital to your car that this sensor is properly maintained. If it's diodes are allowed to get dirty such as by having a dirty air filter, then the readings it takes will be inaccurate and the cars' performance will suffer. If the diodes break, you will not be able to drive the car and a new sensor is expensive.
DO NOT buy into snake-oil products like MAF cleaner...it is an expensive gimmick plus spraying anything under pressure into the sensor can break the diode filaments, some of them are barely .010" thick. Just remove the sensor with the proper bit and carefully poor a stream of isopropyl alcohol (isohol, rubbing alcohol) over the diodes until they shine. Then rinse with water and let air dry.

Yes, your intercooler is a problem cos it cools down the turbo charger. The turbo is what gives you your extra power, and when it overheats, it loses pressure and thatcauses loss of power.
