P0735 Gear 5 Incorrect Ratio

Transmission

P0735 means the transmission is slipping in fifth gear.

In fifth gear, the input and output speeds don't match the fifth-gear ratio: the transmission is slipping in fifth or not completing the shift.

Can I keep driving? Not if you can avoid it.

Drive as little as possible. Slipping wears the transmission quickly.

Common causes

  1. Low or burnt fluid
  2. Worn clutch pack for fifth gear
  3. A shift solenoid or valve body problem
  4. A speed sensor reading wrong

Symptoms

  • Slipping at highway speed
  • Engine revs flaring on the shift into fifth
  • Limp mode

What to check first

  1. Check fluid level and condition.
  2. Check for solenoid or speed sensor codes.
  3. Look for service bulletins and software updates.
  4. Have a transmission shop diagnose it if needed.
