What it means

On Ford vehicles P1762 means the transmission control module has detected that the overdrive band has failed off, so it is not applying when commanded. The module compares the commanded gear and shift solenoid state against input and output shaft speed ratios and sees slip or a ratio that does not match the gear it asked for. It is a hydraulic or mechanical transmission fault rather than an engine fault.

Symptoms

  • Transmission warning or check engine light on
  • Engine revs flare or slip when shifting into or while in overdrive
  • No overdrive or the car stays in a lower gear
  • Poor fuel economy and higher revs at motorway speed
  • Harsh, delayed or inconsistent shifts
  • Transmission may default to limp mode

Possible causes

  • Low or degraded transmission fluid, or the wrong fluid typelikely
  • Worn or burnt overdrive band or clutch components inside the transmissionlikely
  • Faulty shift solenoid or solenoid body, or sticking valve in the valve bodypossible
  • Low line pressure from a worn pump, blocked filter or internal fluid leaks past sealspossible
  • Damaged wiring, poor connector contact or corrosion on the transmission harnesspossible
  • Faulty speed sensor giving a false ratio readingrare
  • Fault within the transmission control modulerare

How to diagnose

  1. Read all stored and pending codes and note the freeze frame data, including speed, load and gear commanded
  2. Check the transmission fluid level, condition and smell, and confirm the correct specification for the model; the procedure depends on the transmission fitted
  3. Inspect the transmission harness and connectors for chafing, fluid ingress, corrosion and bent pins
  4. Check for other transmission codes, such as solenoid or speed sensor faults, which narrow down the cause
  5. Review live data for input and output shaft speed, commanded gear and solenoid states during a road test to see when slip occurs
  6. Check for technical service bulletins or calibration updates for the specific model and transmission
  7. Carry out a line pressure test following the manufacturer procedure for that transmission
  8. If the above is clear, drop the pan and inspect for debris or friction material, then assess the need for internal inspection

How to fix

  • Correct the fluid level or replace degraded fluid and filter using the specified fluid
  • Repair or replace damaged wiring and connectors on the transmission harness
  • Replace faulty solenoids or clean or replace the valve body as diagnosed
  • Replace a faulty speed sensor if live data shows it is incorrect
  • Repair or overhaul the transmission, including the overdrive band and clutches, if wear or damage is confirmed
  • Update the control module calibration only if a bulletin identifies an outdated calibration as the cause

Can I keep driving?

High severity

Limit driving, as continued slip can quickly burn the band and clutches and turn a repairable fault into a full transmission rebuild. If it must be moved, keep speeds and loads low and get it inspected promptly.
