how to resolve P0700 code in Ram 1500 DT (2019-Present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Check and Change Transmission Fluid

• Step 1: Remove the transmission fluid dipstick and check the fluid level. If low, add the correct type of transmission fluid (consult owner's manual).
• Step 2: If the fluid is contaminated, drain the old fluid by removing the transmission pan bolts and carefully lowering the pan.
  • Tools Required: Socket set, fluid catch pan.
• Step 3: Clean the pan and replace the filter if applicable. Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (typically 10-15 ft-lbs).
• Step 4: Refill the transmission with fresh fluid through the dipstick tube.

3. Inspect and Repair Wiring/Connectors

• Step 1: Visually inspect wiring harnesses leading to the TCM for any signs of wear or damage.
• Step 2: Use a multimeter to check continuity and resistance in the wiring. Repair or replace any damaged wires or connectors.

4. Replace Transmission Control Module (if necessary)

• Step 1: If the TCM is faulty, locate it (usually found near the transmission).
• Step 2: Disconnect electrical connectors and remove the TCM from its mounting.
  • Tools Required: Socket set, screwdriver set.
• Step 3: Install the new TCM and reconnect the electrical connectors.
• Step 4: Reconnect the battery.
