Where the tcc pwm solenoid goes in my cutlass ciera 3.1 1995, inside the transmission or outside?

SOURCE: 2002 Sunfire TCC Solenoid replacement

hi..the transaxle converter clutch . tcc. uses a solenoid -operated valve located in the automatic transaxle to mechanically couple the engine flywheel to the output shaft of the transmission through the torque converter.that reduces the slippage loss in the converter.reducing emissions.but check the vss first.which is called the vehicle speed sensor.they both work together .if the vss is not working right it wont call on the tcc.
check this out..
thank u..
rate me..

If it is in the solenoid itself, yes. If it is in the wiring or the computer, no. The only way to tell, is to replace the solenoid and turn off the light. Or do some extensive search in the wiring harness.

it should take approximately 4 - 5 hours plus the cost of sensor

DTC P1744 is "TCC - Excessive Slip Detected During Full TCC Engagement". Which means that the Torque Converter Clutch (TCC) is disengaged or the EPC pressure is at the minimum.

The most likely cause is a sticking or bad TCC solenoid inside the transmission. You can check the connector at the transmission to make sure it is clean and tight and that it is not damaged in any way.

If the TCC and wiring is okay, then pressure testing of the transmission will need to be done.

A new torque converter from Ford is about $265.00 and about 4 hours labor. Throw in a $40.00 TCC solenoid and I don't think it'll be more than $700.00 at worst.

If the pressure test is good then it's just going to be the $40.00 tcc solenoid and the cost of the transmission oil and filter changed which should be around $150.00

Good luck and hope it's just a loose wire harness to the solenoid which would cost $0.00 and just your time to locate the break in the wire. The other thing to, is to add a transmission fluid additive that would restore the clutch pack in the transmission and Torque Converter.

Hi, the likely problem is that your torque converter clutch (TCC) solenoid has failed and will no longer engage the clutch. However, it may be worth a try to have your transmission fluid flushed and the filter replaced, if you haven't done that recently. There is some small chance that will fix the problem. The TCC is a device in the transmission that locks the engine to the transmission once you reach highway speeds of at least 25 mph or higher. The purpose of the clutch is to conserve fuel and reduce heat in the torque converter. The car will run fine without the TCC, but will get slightly less highway mileage. There is no harm or safety concern with driving the car as it stands now. However, if you intend to keep this car and drive a lot of highways miles, it may be worth the expense to have it repaired. (you could check your mileage to see how it's doing without the clutch) The repair should be done by a transmission expert, as there are several possible reasons it has failed--I'm only guessing it's the solenoid but would HAVE to troubleshoot to be sure. The repair can be done by any reputable transmission shop--it does not have to be done at the Cadillac/GM dealer. That said, I do recommend you shop around a bit if you want to have the car repaired, as there is considerable variation in the approach to this repair. It is possible to replace the solenoid without removing the transmission, but some shops may claim you need a complete rebuild. Make sure to tell them your trouble codes--that was very helpful to me. Please let me know if you have any questions, and thanks for using FixYa.
