P0742 on Chrysler by model: symptoms, diagnosis and fix
The ZF 8-speed automatic develops harsh shifting, especially in 2nd gear. Valve body is primary failure point. Cold shifting particularly problematic. Chrysler states "sealed for life" but failures occur before 150,000 miles.
Common Symptoms
- Harsh downshift from 2nd to 1st with jerking
- Rough upshift from 2nd to 3rd with RPM spike
- Noticeable clunk when shifting, especially cold
- Delayed shifts or hesitation
How to Fix
Dealer must replace transmission valve body under warranty if applicable. Ensure TCM updated to latest software. Perform Quicklearn procedure after work. Use only ZF-approved fluid.

The ZF 9HP48 9-speed automatic transmission suffers from harsh shifting, delayed engagement, lurching forward, and unexpectedly shifting into neutral while driving. A terminal crimping issue in sensor cluster harness assemblies caused wiring defects. 2015 models are worst; 2016+ have improvements after FCA built transmissions in Kokomo, Indiana. Recall S55 (NHTSA 16V529000) issued.
Common Symptoms
- Hard shifts between 2nd and 3rd gear
- Transmission unexpectedly shifts into neutral
- Lurching forward after downshift
- Delayed engagement when shifting from Park
- Service Transmission warning light
How to Fix
Contact dealer for Recall S55 (NHTSA 16V529000) - provides free PCM/TCM reprogramming and transaxle range sensor wire harness replacement if needed. If ordering 2015 replacement transmission, the system automatically provides improved 2016 unit. Regular transmission fluid services every 60,000 miles.

The first-generation Chrysler 200 (rebadged Sebring) uses the 62TE 6-speed automatic which suffers from solenoid pack failures, valve body issues, and worn sealing rings. Hard shifting, slipping, and complete failure are common, often before 100,000 miles.
Common Symptoms
- Hard shifting or jerking between gears
- Transmission slipping under load
- Delayed engagement from Park
- Stuck in 3rd gear (limp mode)
- Transmission overheating
How to Fix
Solenoid pack replacement (68376696AA) for early symptoms. Full transmission rebuild or replacement for severe cases. Use ONLY Mopar ATF+4 fluid (68218058AC). Change fluid every 30,000 miles.

The 62TE 6-speed automatic transmission experiences solenoid pack failures causing hard shifting, slipping, limp mode (stuck in 3rd gear), and complete transmission failure. The solenoid pack contains 6 shift solenoids, 1 line-pressure solenoid, a temperature sensor, and 5 pressure switches. Most frequent in 2012 and 2014 models.
Common Symptoms
- Hard shifting between gears
- Transmission slipping during acceleration
- Stuck in 3rd gear (limp mode)
- Overheating transmission warning
- Sudden loss of acceleration
- Delayed engagement from Park to Drive
How to Fix
Start with solenoid pack replacement (68376696AA or 5078709AB). If internal damage present, full transmission rebuild ($2,500-$4,500). Always use ONLY Mopar ATF+4 fluid (68218058AC). Change fluid every 30,000 miles despite Chrysler's lifetime claim.

The A604 (41TE) transmission used in 2001-2006 models and the 62TE 6-speed transmission in 2007-2010 models are prone to slipping between gears, hard shifts, and delayed engagement. The A604 has known OE design flaws, while the 62TE commonly experiences solenoid pack failures.
Common Symptoms
- Slipping between gears
- Hard or rough shifting
- Delayed engagement into Drive or Reverse
- Failure to upshift at highway speeds
- Transmission warning light
- Stalling when coming to a stop
How to Fix
For minor shifting issues, a transmission fluid and filter change may help ($150-$300). Solenoid pack replacement costs $400-$800. For severe issues, a transmission rebuild costs $1,800-$3,500, while a complete replacement costs $2,500-$4,500.

The 948TE 9-speed automatic paired with the 3.6L Pentastar V6 has well-documented calibration issues. Hesitation during light-throttle acceleration, delayed 2nd-to-3rd upshifts, and shuddering under load. For 2023+, Chrysler introduced revised valve body and updated shift logic with fewer complaints.
Common Symptoms
- Hesitation during light-throttle acceleration
- Delayed 2nd-to-3rd gear upshift
- Shuddering under load at low speeds
- Harsh downshifts
- Occasional clunk when shifting from Park
How to Fix
Get latest PCM/TCM software update from dealer (often resolves 80%+ of shifting complaints). For 2020-2022, updated 2023 valve body can be installed. Regular transmission fluid service every 60,000 miles.

Frequently asked questions
What does P0742 mean on a Chrysler?
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 Chrysler it is documented across 5 models: 300, 200, Town & Country, Sebring, Voyager.
What are the most common causes of P0742?
The most common causes of P0742 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0742 on a Chrysler?
Published repair estimates on Chrysler range from $300 to $6,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
