Lockup TCC Wiring TH700R4InternalWiringDiagram01.jpg (267389 bytes)Engine Diagram Torque Converter Clutch - Engine code says Torque converter clutch system stuck. Probable causes: TCC solenoid failure or check transmission range switch for proper operation.. Connects to the crankshaft at the rear of the engine. Transfers torque from the crankshaft to the clutch or torque converter. routes exhaust gases out of cylinder head and into catalytic converter. oil pan. holds engine oil for lubrication. oil filter.. Torque Converter Clutch. The torque converter clutch creates a one to one connection between the output of the engine and the input of the transmission. This increases fuel mileage and reduces transmission fluid temperatures. This is because of normal torque converter slippage between the impeller and turbine..
Torque Converter Clutch Solenoid. As with most items on a modern car, torque converters do have a measure of solenoids in them that can go bad and fail.. Probably torque converter clutch isn’t working (ie isn’t locking up at highway speed. Normally it should lock up at 45+ mph).The result is slightly higher engine RPM on the highway and worse gas mileage.. An automatic transmission uses a torque converter to pass energy from the engine into the transmission. A torque converter is essentially a tub of fluid secured to the engine's flywheel that acts like an adjustable vise when spinning..
To allow firm shifting without the engagement of the torque converter clutch, place the Co-Pilot computer one setting below the maximum (the right two blue LEDs will be will be on and no check engine light will be set at this point).. Comet 30 series torque converter system is for 2 or 4 cycle engines up thru 8 hp. The model 30 uses a 3/4" top width asymmetric belt. Drive clutches are available for both 3/4" and 1". Location: Engine Compartment Black A - Red B - Black C6 C7 Output Speed Sensor (TOSS) Location: 4L60E/4L65E 2WD - Tailhousing 4L60E/4L65E 4WD - Transfer Case 4L80E - Driver side of case, rear sensor. Economy/Performance (Optional) Location: Dash mounted toggle or rocker switch C8 Torque Converter Clutch (TCC - common) Location: Next to TCU.
The major components of a torque converter are: the impeller, the turbine, the stator, and the lock-up clutch. The impeller is part of the torque converter housing, which is connected to the engine.. The torque converter in an automatic transmission serves the same purpose as the clutch in a manual transmission. The engine needs to be connected to the rear wheels so the vehicle will move, and disconnected so the engine can continue to run when the vehicle is stopped.. Unfortunately, this torque converter clutch is automatically unlocked whenever the driver removes his foot from the accelerator, essentially letting the truck freewheel down a hill with little engine braking. For towing a heavy trailer, it would be nice to keep this clutch locked while decelerating, giving much more effective engine braking..
- Torque converter clutch solenoid valve circuit is open or shorted - Transmission internal mechanical problem The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM).. The whole concept behind a torque converter is to relieve you of the need for a clutch. The way that this is facilitated is the “stall speed”. Stall speed allows the engine to idle while barely applying any pressure to the rest of the drivetrain..
