I have these codes coming up p0700, p1684, p0562, p0218, u0156, uo184 and I am wondering how much the fix will be and how serious it is? Also, wondering if the electronic control board is okay?
Do you
have the same problem?

Good morning my name is Roy and I will assist.

The 700 and the 1684 are together. It indicates a loss of battery power to the transmission. Below is the description.

Did someone remove a battery cable either with the engine off or running?

Roy

P1684-Battery was disconnected.
For the transmission circuit diagram, refer to wiring diagram information.
When monitored:
Whenever the ignition is in the run/start position.
Set condition:
This DTC will set whenever power-train control module is disconnected from fused B+ or ground. It will also be set during the DRBIII(R) battery disconnect and/or quick learn procedure.

Possible causes:
Battery was disconnected

- Scan tool battery disconnect performed.
- PCM was replaced or disconnected.
- Quick learn was performed.

Okay, here is the 218.

As far as an estimate, it is impossible to give you an estimate until diagnostics are done and the failure determined. That will need to be done by someone with a scan tool. Diagnostics start at about $100.00 and up depending on the amount of time it takes to find the failure. Codes do not identify bad parts just failed systems. That is why diagnostics need to be done. Below is the description of the 218.

Roy

P0218-High temperature operation activated
For the transmission circuit diagram, refer to wiring diagram information.
When monitored:
Whenever the engine is running.
Set condition:
Immediately after a overheat shift schedule is activated when the transmission temperature exceeds 127 C or 260 F.

Possible causes
- High temperature operation activated
- torque converter clutch slipping/not activating
- excessive time idling in gear
