Best to clear the computer codes & see what codes if any come back. You will need a scanner that can clear codes to do it .. Or if there is an Auto Value around you they can do it.
If P1738 returns I would bring the car back to the transmission shop.
I put the code details below.
P1738: Problem in 2nd Clutch Pressure Switch Circuit
P1456: Evaporative Emission Control System Leak Detected Small Leak
- Missing Fuel cap - Incorrect fuel filler cap used - Fuel filler cap remains open or fails to close - Foreign matter caught in fuel filler cap - Incorrect fuel tank vacuum relief valve - Leak is in line between intake manifold and EVAP canister purge volume control solenoid valve.
P0766 - Shift Solenoid D Performance or Stuck Off.
Check in THIS LINK the test and solution procedure.
Both codes are related to the Direct clutch (5th gear). Code 2703 states
to change out the solenoid (SSPC-D)and clear the code. If the codes
come back then you must overhaul the trans and repair the leaking or
slipping direct clutch.
p0217 is coolant over temperature. the fan clutch may be slipping or the thermostat is bad. changing the thermostat would probably be the easiest and most inexpensive fix to determine the problem.
Hi Code P 0217 does point to the thermostat but it also points to the wiring, cooling system, and the temperature sensor, to check the thermostat start engine then once the temperature gauge in the car reaches normal the thermostat should open and the top hose that goes into the radiator will warm up quickly as the thermostat opens, if the thermostat is stuck in it's open position the top hose will start warming up before the engine reaches it's working temperature, hopefully i have explained it clearly,
