P0742 on Honda
Torque Converter Clutch Circuit Stuck On
P0742 on Honda vehicles indicates torque converter clutch circuit stuck on. Au7o has documented this code across 3 Honda models — most commonly on Crosstour, Odyssey, Passport. P0742 means the torque converter clutch (TCC) circuit is stuck on, meaning the lockup clutch that mechanically links the engine to the transmission stays engaged when it should release. The computer commands the clutch on and off, and when it detects the converter clutch remaining applied, it sets this code. The classic symptom is the engine stalling when coming to a stop, similar to driving a manual without pushing the clutch in, along with possible harsh shifts or poor fuel economy. It points to a hydraulic or solenoid problem inside the transmission rather than the engine. Typical repair costs on Honda range from $80 to $7,000, depending on the specific model and root cause.
Common Causes of P0742
- •Stuck or failed torque converter clutch solenoid
- •Stuck valve in the valve body (TCC apply valve)
- •Contaminated or degraded transmission fluid
- •Internal transmission hydraulic leak holding the clutch on
- •Wiring or connector fault to the TCC solenoid
- •Faulty torque converter
- •Dirty or clogged transmission filter
P0742 on Honda by Model
Honda Crosstour(2 issues)
- Transmission Shudder and Hard Shifting2010-2015
Honda Crosstour (2010-2015) owners report transmission shuddering, hard shifting, slipping gears, and hesitation during acceleration. The 5-speed automatic transmission experiences torque converter shudder at low speeds (15-35 mph) and harsh shifting between gears. Honda issued software updates for torque converter control, but many owners report issues persist. Transmission fluid flush may help temporarily.
- Transmission Parking Pawl Failure (Vehicle Rolls Away)2010-2015
The Honda Crosstour (2010-2015) has a serious transmission defect where pieces of the ball bearing from the secondary shaft can become lodged in the parking pawl, causing the transmission to slip when put into Park. This results in the vehicle rolling away unexpectedly, creating a serious safety hazard. Honda issued a recall for the transmission control module software to prevent engine stall, but the parking pawl issue persists. Symptoms include transmission slipping in Park, vehicle rolling on incline when in Park, and grinding noise when shifting.
Honda Odyssey(2 issues)
- ZF 9-Speed Transmission Shudder and Harsh Shifting2018-2019
The ZF 9HP 9-speed automatic transmission experienced severe drivability issues from programming defects. Software-controlled dog clutches proved incompatible with Honda's calibration, causing violent shaking/juddering, hesitation when accelerating from stops, and harsh downshifts at low speeds. Multiple class-action lawsuits filed against Honda.
- Torque Converter Shudder (6-Speed Auto)2011-2017
Judder from torque converter lock-up clutch felt while driving between 20-60 mph. Honda determined the judder was caused by deteriorated transmission fluid exposed to intermittent high heat loads under specific driving conditions. Most noticeable during light acceleration when torque converter attempts to lock up.
Honda Passport(2 issues)
- 9-Speed Transmission Rough Shifting and Hesitation2019-2023
The Honda Passport (2019-2023) with the ZF 9-speed automatic transmission experiences rough shifting, delayed shifting, harsh acceleration/deceleration, sudden loss of power, and transmission slipping into neutral unexpectedly. A class action lawsuit alleges the transmission control module (TCM) and powertrain control module (PCM) are miscalibrated, causing dangerous failures. Owners report the transmission downshifting harshly at highway speeds, hesitating when accelerating from a stop, and in severe cases, dropping into neutral while driving. Honda has issued multiple software updates (TSBs) but many owners report issues persist.
- Highway Vibration and Wobble (45-65 MPH)2019-2023
Honda Passport owners report annoying vibration and wobble at highway speeds (45-65 mph). The vibration is cyclical, often felt through the steering wheel, floor, and seats. Common causes include: wheel balance issues (OEM wheels are finicky), tire cupping/uneven wear, driveshaft imbalance, transmission torque converter shudder, and worn suspension bushings. Some owners report Honda dealers dismissing it as "normal characteristic" despite it being clearly abnormal. Road force balancing (not regular balancing) often fixes tire-related vibration.

What does P0742 mean on Honda?▼
P0742 stands for "Torque Converter Clutch Circuit Stuck On." P0742 means the torque converter clutch (TCC) circuit is stuck on, meaning the lockup clutch that mechanically links the engine to the transmission stays engaged when it should release. The computer commands the clutch on and off, and when it detects the converter clutch remaining applied, it sets this code. The classic symptom is the engine stalling when coming to a stop, similar to driving a manual without pushing the clutch in, along with possible harsh shifts or poor fuel economy. It points to a hydraulic or solenoid problem inside the transmission rather than the engine. On Honda specifically, this code is documented across 3 models.
What causes P0742 on Honda vehicles?▼
Common causes on Honda: Stuck or failed torque converter clutch solenoid, Stuck valve in the valve body (TCC apply valve), Contaminated or degraded transmission fluid, Internal transmission hydraulic leak holding the clutch on, Wiring or connector fault to the TCC solenoid. Specific causes vary by model and year — see the per-model sections below.
