We have the codes PO700 and PO741 on our 2005 Subaru Outback. We're told that is a transmission issue code. Trying to get a general idea of how much it would cost to repair this. Any thoughts?

P0741 is for the Torque Converter Clutch solenoid circuit performance / stuck.
P0700 is transmission control MIL request. Probably just a benign secondary code generated when the TCU sends info to the ECU to light the MIL (Check engine light). This will likely go away once the TCC solenoid issue is fixed.

First things first. What is the fluid condition? Is it old? Burned? Cruddy fluid can cause the TCC solenoid to jam and not respond. New fluid may be able to dislodge the solenoid and restore proper operation for about $80 if you can change the transmission fluid and filter yourself.

Worst case you have to replace the solenoid which could be anywhere from $500 -$1000 or possibly more between parts and labor, depending on the labor rates of the shop that does the repair.

If you're a DIY person the solenoids are sometimes easily removed once the transmission pan is off. But this particular solenoid may require removal of the valve body to get access.
