What is the upshift delay code for automatic transmissions?
It is the upshift delay codes P1700 and P1701. These codes would only apply to the mechanically controlled automatic transmissions used before 1996. Those transmissions used a throttle pressure cable (control pressure) for determining shift points under various loading.
What does it mean when upshift delay is not working?
It simply means that the upshift delay function is not working. The s/o valve is cheap – less than $50, but the problem is 95% of the time a vacum leak in the switch over valve itself, which is located on the side of the transmission.
Where is the upshift delay switch over valve located?
The most common cause is a vacuum leak, hoses on the vacuum supply check valve going to the switchover valve. The switchover valve is mounted on the firewall behind the brake master cylinder. It has a black wire going to it (electrical) and a green hose (vacum). You can apply vacum to the green line to see if the upshift delay valve holds vacum.
What to do when your transmission is stuck in limp mode?
The majority of the time, the problem is not as grave as you may think. If your transmission is stuck in gear and you are far away from home, try this: Pull over and turn the car off. Remove the key. Do not press the gas pedal or any other buttons on the car. Wait 20 seconds. Start the car and drive to see if it is out of limp mode.

What does p1700 mean on a powertrain control module?
P1700 Meaning The Powertrain Control Module (PCM) monitors the Transmission Control Module (TCM). The Diagnostic Trouble Code (DTC) will set when the TCM determines that is an internal transmission problem. If other DTCs are present, diagnose, and repair them first.
What are the possible causes of a p1700 code?
P1700 Possible Causes 1 Check for codes in Transmission Control Module (TCM) 2 Faulty internal component 3 Faulty Direct One-Way Clutch
When does the diagnostic trouble code ( DTC ) set?
The Powertrain Control Module ( PCM) monitors the Transmission Control Module (TCM). The Diagnostic Trouble Code (DTC) will set when the TCM determines that is an internal transmission problem. If other DTCs are present, diagnose, and repair them first.
