The "TCC release switch malfunction" typically refers to an issue with the Torque Converter Clutch (TCC) system in a vehicle's transmission. This malfunction indicates that the switch responsible for engaging or disengaging the torque converter clutch is not functioning properly, which can lead to poor vehicle performance, slipping, or overheating. It may trigger warning lights on the dashboard and could result in reduced fuel efficiency or transmission issues. Addressing this malfunction usually requires diagnostic testing and potential repair or replacement of the faulty components.
P0740 = TCC (Torque Converter Control) Circuit Malfunction.
The tcc switch (tcc brake switch) is located under the dash near the brake pedal. The tcc solenoid is located under the side cover in the transmission/transaxle. The tcc switch (tcc brake switch) is located under the dash near the brake pedal. The tcc solenoid is located under the side cover in the transmission/transaxle. The tcc switch (tcc brake switch) is located under the dash near the brake pedal. The tcc solenoid is located under the side cover in the transmission/transaxle.
The TCC *solenoid* for my 1985 (very similar, probably the same) is inside a cover plate on the side of the transmission (AT125?). There are 12 or 16 bolts that hold the plate on, and the TCC solenoid is inside there. Not hard to do, just hard to get to without a lift.
Im going to assume the code you have given is PO740 on the obd2 scan tool? PO740 is a TCC circuit malfunction
Code Make Description P1887 Ford Four-wheel drive control solenoid circuit failure P1887 GM TCC Release Switch Malfunction P1887 Mazda Four-wheel drive control solenoid circuit failure As its a Daewoo possible the middle one as its a gm engine Can you tell me where the obd 2 connector is on your car
check tcc switch, torque converter switch.
Is it located inside of the side transmission pan
its on left side of trans behind side pan
The TCC switch is located next to the brake switch at the top of the brake pedal, under the dash.
I have a 97 Dodge and I'm getting the same code which means "solenoid switch valve latched in TCC position" Tryin' to figure it out myself!
A TCC (Torque Converter Clutch) solenoid switch is typically not under vacuum; it operates using hydraulic pressure from the transmission fluid. The solenoid controls the engagement and disengagement of the torque converter clutch, allowing for improved fuel efficiency and smoother driving. While vacuum can be relevant in other automotive systems, TCC solenoids primarily rely on electrical signals and hydraulic pressure.
Not sure what a TCC (Torque Converter Clutch) sensor is. There is however a TCC relay and a TCC solenoid. The TCC relay is found in the relay/fuse center and the TCC solenoid is located inside the transmission.
