You may want to have someone else take a look at it. The Nissan P1800 trouble code is not a transmission control problem. It is described as follows:

Trouble diagnosis name: VIAS control solenoid valve circuit.
Component Description:
The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator.
DTC detecting condition:
•An excessively low or high voltage signal is sent to ECM through the valve.
Possible cause:
•Harness or connectors (The solenoid valve circuit is open or shorted.)
•VIAS control solenoid valve

Check your vacuum hoses to make sure they are in good shape and are securely attached Aslo check the wiring harness is ok and securely attached as well. If they are, you’ll probably need to replace your VIAS. It's right next to the throttle body.

My 05 Altima 3.5L popped up ABS, O2sensor, P1800 &P1273 frm the Auto Scan what do these mean & how to fix them?


P1800 is the VIAS system. Most likely the intake runner control vacuum actuator is defective. Where did you get the ABS info?
P1273 NISSAN - Air Fuel Ratio Sensor 1 Bank 1 Lean Shift Monitoring.
Possible causes - Faulty Air fuel ratio (A/F) Sensor 1 Bank 1
-Intake manifold or vacuum hose leaking (check this first)
- Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted
- Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
- Fuel pressure
- Faulty Fuel injector
- Faulty Air Flow Meter
If all seems ok then replace the cylinder bank number one O2 sensor and the bank two sensor, replacing only one sensor can lead to another check engine light. These are the sensors before the catalytic converter.
