Fixing the Manual Swap Codes
Well have been working on cleaning up a few things, and am looking at a temporary fix (short of an ECU swap) to get rid of the codes that pop from the manual transmission swap. Can someone with an I4 Swap, and others who have also done the swap, verify/confirm the codes that are popped?
Here are the relevant codes that pop for me:
P0743 Torque Converter Clutch Circuit Electrical
P0753 Shift Solenoid A Electrical
P0758 Shift Solenoid B Electrical
P0763 Shift Solenoid C Electrical
P0768 Shift Solenoid D Electrical
I'm guessing that the ECU is just looking for a certain voltage range for the different circuits, and if we can just provide a steady voltage to each, then the ECU would act as if all is well.
So far, from the service manual, the Torque Converter Clutch Circuit, and apparently all the Shift Solenoid Circuits should have a reading between 2.6ohms and 3.5ohms.
All the wires appear to be on connector B-38:
Pin 3, Red, Under-Drive Solenoid Valve
Pin 4, Red-Yellow, Second Solenoid Valve
Pin 5, Blue, Overdrive Solenoid Valve
Pin 6, Red-White, Low/Reverse Solenoid Valve
Pin 7, Yellow-Red, Torque Converter Clutch Control Solenoid Valve
Underdrive Solenoid: Resistance between pins 3-9 should be at 2.7 - 3.4 ohms
Second Solenoid: Resistance between pins 4-9 should be at 2.7 - 3.4 ohms
Overdrive Solenoid: Resistance between pins 5-9 should be at 2.7 - 3.4 ohms
Low-Reverse Solenoid: Resistance between pins 6-10 should be at 2.7 - 3.4 ohms
Torque Converter Clutch Control Solenoid: Resistance between pins 7-10 should be at 2.7 - 3.4 ohms

Pins 9 and 10 appear to go to a power source.
