how do I fix P0700 code on my Ram 1500 DT (2019-Present)?

Solution

1. Preparation

• Gather necessary tools and parts. Ensure you have a clear workspace and access to the vehicle's onboard computer.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Inspection and Replacement

• Tools Required: Transmission fluid pump, funnel, socket set.
• Remove the transmission dipstick (if applicable) and check the fluid level.
• If fluid is low or burnt, drain the old transmission fluid using a fluid pump.
• Replace with manufacturer-recommended transmission fluid (e.g., Mopar ATF+4).
• Refill the transmission to the proper level.

3. Wiring and Connector Inspection

• Tools Required: Multimeter, socket set.
• Visually inspect the wiring harness leading to the TCM for frays or breaks.
• Use a multimeter to check the continuity of the wires from the TCM to the transmission.
• Repair or replace any damaged wiring or connectors as needed.

4. TCM Testing or Replacement

• Tools Required: Scanner capable of reprogramming the TCM (if replacement is needed).
• If the TCM is faulty, remove it from the vehicle by unbolting it and disconnecting the harness.
• Install a new or refurbished TCM and reprogram it according to the manufacturer's instructions.
• Reconnect the battery terminal.
