Our jeep 2005 grand cherokee check engine light is on, codes p0740 & p0700 but there are no performance issues.

The P0700 code is an information code that means the transmission control module has requested the check engine light be turned on.
The second code is a problem with the torque converter solenoid. It is possible low or dirty transmission fluid is bringing up this code.
