Top 5 Issues 1st Gen Nissan Titan (2004 to 2015)

1. Transmission Problems: Coolant Mixing with the Transmission Fluid

Symptoms of Transmission Problems

  • Lack of engine power
  • Poor shifting
  • Overheating
  • Coolant level is often low
  • Sudsy transmission fluid
  • Dark pudding-like coolant

Another indicator of the coolant mixing with the transmission fluid is the coolant disappearing from the radiator after topping it off.

Causes of Transmission Problems on the 1st Gen Nissan Titan

The transmission lines that run through the radiator can crack, allowing coolant to flow into the transmission.

How to Fix Coolant Mixed with the Transmission Fluid

Check the Transmission Fluid’s Condition

If you need to keep refilling the coolant, it may not be the head gaskets. Check the transmission fluid first.

How to Check the Transmission Fluid on the 2004 to 2015 Nissan Titan

  1. Warm the Engine Up to Operating Temperature

    Warm the engine up to operating temperature to get an accurate reading of the transmission fluid

  2. Park on Level Ground

    Park on level ground away from bystanders or traffic

  3. Remove the Bolt from the Transmission Dipstick Bracket

    Loosen and remove the bolt from the transmission dipstick bracket with a 10mm socket and ratchet

  4. Remove the Transmission Fluid Dipstick

    Remove the dipstick and clean it with a cloth

  5. Reinsert and Remove the Transmission Fluid Dipstick

    Check the condition of the transmission fluid. If there is coolant in the transmission fluid, it will separate in the form of bubbles.

Check the Coolant Overflow Tank for Mud-Like Residue

With the truck cool, remove the coolant overflow tank cap. If the coolant is mixing with the transmission fluid, a mud-like fluid will accumulate around the cap.

Flush or Repair the Transmission and Replace the Radiator
  • If this problem is caught before there is damage to the transmission, replacing the radiator and flushing the transmission fluid will fix this issue.
  • If the transmission is damaged, the transmission will need to be rebuilt or replaced along with the radiator.

2. Broken Clock Spring Wiring

Symptoms of a Broken Clock Spring

  • Air bag light is on
  • Check engine light for code P1654 or U1000

Causes of a Broken Clock Spring

The wiring to the clock spring can fray and break off in the 2004 to 2015 Nissan Titan.

How to Fix a Broken Clock Spring

  1. Clear the code
  2. Start the truck
  3. Turn the steering wheel from stop-to-stop, i.e. a full 360 degrees turn or 180 degrees each way.
  4. If the check engine light and air bag light return, there is likely a problem with the clock spring.

3. Catalytic Converter Failure

Symptoms of Bad Catalytic Convertors or Fuel Pump Problems on the 2004 to 2015 Nissan Titan

  • Lack of power when accelerating

Causes of Bad Catalytic Convertors

Low fuel pressure can damage the catalytic convertors.

How to Fix Bad Catalytic Convertors

Check the fuel pressure. If the fuel pressure is below 51 psi, there is a lean condition, meaning the truck is starved for fuel and the fuel pump needs to be replaced. Not replacing the fuel pump as soon as possible can damage the catalytic convertors.
