P1740 on Nissan
Torque Converter Clutch System Fault (Manufacturer Specific)
P1740 on Nissan vehicles indicates torque converter clutch system fault (manufacturer specific). Au7o has documented this code across 1 Nissan model — most commonly on Rogue. This is a manufacturer-specific transmission code indicating a fault in the torque converter clutch (TCC) system. The torque converter clutch mechanically locks the engine to the transmission at cruising speeds to reduce slippage and improve fuel economy; the computer controls it with a solenoid and monitors whether it locks and unlocks correctly. This code sets when the system doesn't behave as expected — for example, the clutch fails to lock, slips, or the control circuit is faulty. Symptoms can include shudder, poor fuel economy, higher RPM at cruise, or a transmission that won't lock up. Typical repair costs on Nissan range from $3,000 to $8,000, depending on the specific model and root cause.
Common Causes of P1740
- •Faulty torque converter clutch (TCC) solenoid
- •Worn or failing torque converter
- •Low, dirty, or contaminated transmission fluid
- •Valve body wear or stuck valve
- •Damaged TCC solenoid wiring/connector
- •Internal hydraulic pressure loss
- •Faulty transmission control module (TCM)
P1740 on Nissan by Model
Nissan Rogue(1 issue)
- JATCO CVT judder, shudder, slipping and complete failure2014-2018
The second-generation Rogue uses a JATCO continuously variable transmission (RE0F10x family) that is widely documented to judder/shudder during light acceleration (typically 25-45 mph), exhibit a 'rubber band' rubbery hesitation from a stop, overheat into limp mode with sudden loss of power at highway speed, and in many cases fail completely before 100,000 miles. CarComplaints lists 111+ power train complaints for the 2014 model alone (severity 10/10), and Nissan accumulated well over 1,000 transmission-related NHTSA complaints across the generation. A class action (Stringer v. Nissan / related Rogue-Pathfinder-QX60 settlement, final approval March 2022) extended the CVT warranty on 2014-2018 Rogues from 60mo/60k to 84mo/84k miles and provided repair reimbursement.
