The Transmission Control Module (TCM) on a Volvo XC90 AWD 2.9 is located under the driver's side dash, attached to the underside of the steering column. It is mounted behind the steering wheel and can be accessed by removing the lower dashboard panel.

If you mean the transmission take it to a tranmission shop to be check out,

The P0700 is not a true fault code, it just means that the powertrain control module has requested the Transmission control module to turn on the check engine light to alert you of a fault. The P0717 is the one you need diagnosed, it is the real problem,.

CODE P1618 - CABLE FAULT BETWEEN AW 50 Q2 TRANSMISSION CONTROL MODULE AND MOTRONIC 4.4 ENGINE CONTROL MODULE. YOU CAN CHECK FOR RECALLS BUT I DONT THINK THERE IS RECALL FOR YOUR PROBLEM. YOUR PROBLEM IN TRANSMISSION CABLE COULD BE LOOSE OUT OF PLACE DAMAGED OR YOU HAVE TCM ECM FAULT.

810 neutral check, incorrect connection

Check the transmission and control module connectors. Check for contact resistance and oxidation according to Checking wiring and terminals. Permanent faults

1132 front o2 sensor signal too high
1618 dtc is in another module
Volvo does not provide information regarding DTC P1633 for many of their models.
However, it has been reported that various Volvo engine control modules will produce this code. The code is associated with a missing or inaccurate vehicle speed signal from the ABS control module and may be accompanied by DTC P0722 or P1618.

Possible causes:
- Defective vehicle speed signal to the ABS control module
- CAN connection problem
- Defective ABS control module
- Defective engine control module

Manufacture codes associated with this P code may include ECM-510f, 530d.

Most likely the transmission range switch is failing.
Have someone check the transmission computer for codes.

These Central Electronics Units(CEMs) are available from used car parts dealers. You need to note all the numbers on your unit(from the label on top). You don't have to completely remove the unit to see these, just remove the trim. You run a risk of course because you will get very little in the way of warranty but it's a whole lot cheaper than paying through the nose for a 'genuine' Volvo spare.
