- Check for any loose or damaged connections in the circuit.
- Inspect the shift solenoid for any signs of damage.
- Replace the shift solenoid if necessary.
- Clear the code and test drive the vehicle to see if the code returns.

FAQ
What is code p1745?
Code P1745 is a generic powertrain code. It’s most likely to be caused by a faulty transmission solenoid, although there are other possible causes as well.
What are the symptoms of code p1745?
There are a few different symptoms that are associated with code P1745, which is a code for a transmission solenoid. Some of the symptoms include the transmission slipping, the engine revving up but the vehicle not moving, and the vehicle jerking when it changes gears. If you are experiencing any of these symptoms, it is important to take your vehicle to a mechanic to have it checked out.
What are the common causes of code p1745?
There are a few common causes of code p1745:
1. A problem with the transmission control module (TCM)
2. A problem with the transmission itself
3. A problem with the wiring or connectors between the TCM and the transmission
4. A problem with the vehicle’s engine speed sensor
How do you diagnose and fix code p1745?
Code P1745 is a diagnostic trouble code (DTC) for “TransmissionSolenoid Malfunction”. This code is set when the transmission control module (TCM) detects a problem with one or more of the transmission solenoids.
There are a few things that can cause this code to set. The most common cause is a problem with the transmission solenoid itself. This can be caused by a short circuit, an open circuit, or a bad connection. Another common cause is a problem with the transmission control module (TCM). This can be caused by a bad TCM, a corrupt software file, or an electrical problem.
The first thing you should do when this code is set is to check all of the connections to the transmission solenoids. Make sure they are all tight and free of corrosion. If they all look good, then the next step is to test the transmission solenoids themselves. This can be done with a multimeter.
If the transmission solenoids test good, then the next step is to test the TCM. This can be done with a scan tool. If the TCM tests bad, then it will need to be replaced. If the TCM tests good, then the next step is to check for any software updates. If there are any updates available, then they should be installed.
If the code still persists after all of these steps have been taken, then the problem may be with the transmission itself. The transmission will need to be replaced if this is the case.
What are the common mistakes made when trying to fix code p1745?
There are several common mistakes made when trying to fix code P1745. First, some people may try to clear the code without first diagnosing the root cause of the problem. This can lead to the code being cleared temporarily, but then returning soon after. Additionally, some people may replace the wrong part when attempting to fix this code. For example, they may replace the transmission solenoid when the actual problem is with the transmission control module. Finally, some people may fail to properly reconnect all the electrical connectors after completing repairs. This can result in the code being thrown again in the future.
