When does the torque converter on a GMC Acadia fail?
When does the torque converter on a GMC Acadia fail?
Automatic Transmission Torque Converter problem of the 2012 GMC Acadia 4 Failure Date: 07/18/2020 The transmission is slipping or shuddering under certain conditions. Most frequently noticeable around the shift points between 2nd&3rd, or 3rd & 4th, especially when the engine is downshifting to climb a hill.
Where is the clutch located in a torque converter?
Also, to prevent stalling when the vehicle is at a standstill, the torque converter acts as a clutch between the engine and transmission. At certain speeds, the torque converter clutch (located inside the converter) creates a mechanical connection between the engine and transmission.
What causes a GM torque converter to lock up?
Most of the time it is a stuck Torque Converter Clutch (TCC) solenoid, but this is not the only cause of this problem. General Motors has issued a few Technical Service Bulletins (TSBs) relating to this problem. There is also a specific diagnostic procedure to determine the exact cause of the TCC problem.
Where is the solenoid valve on a torque converter?
Today we’ll be dealing with a Torque Converter Clutch Solenoid Valve. You will see how to locate, remove and test this solenoid valve. The torque converter on an automatic transmission transmits engine torque and power to the transmission. To prevent slippage a lockup clutch is located inside the converter.

What is the purpose of the torque converter clutch?
The purpose of the Transmission Converter Clutch (TCC) feature is to eliminate the power loss of the torque converter stage when the vehicle is in a cruise mode. The TCC System uses a solenoid-operated valve to couple the engine flywheel to the output shaft of the transmission through the torque converter.

Can a torque converter be a problem with a transmission?
It could be a problem with the transmission, or the transmission could be perfectly fine and it could be a problem with the torque converter. Torque converter issues on a lot of older transmissions can be diagnosed by carrying out a stall-speed test. Below we have outlined how you can safely and easily conduct a torque converter test.
