SOURCE: do i drain the transmission fluid before removing

there is not drain, so you just drop the pan and try not to get soaked in fluid, i use a plastic garbage can lid with holes drilled in it to catch the fluid, this is the best way, and yes the solenoid is mounted to the bottom of the valve body inside the transmission, only way to access the part is by removing the trans pan.

SOURCE: how do i know if its my tcc solenoid and not the

If the solenoid is stuck so the torque converter remains locked, the transmission will not be able to shift down and the engine may stall when you slow down from highway speed. This seems to be the most common problem with this part, and it shows up primarily in prolonged high-temperature running.

If you can get the vehicle into reverse with a locked torque converter, you may have to maintain a minimum speed to keep from stalling the engine - not a safe situation.

My experience with hanging TCC solenoids is that they usually release the clutch if they are allowed to cool for a few minutes, if they don't release when the engine stalls.

If the TCC is not locking the torque converter, there will be no difference in high-speed performance when you disconnect the TCC solenoid. If the TCC is working to this extent, disconnecting it will cause a lag in acceleration and loss of gas mileage in high gear. Unfortunately, this is not a completely definitive test; it does not rule out a malfunction in the torque converter clutch mechanism.

I have a 2001 aurora and code p1860 p1860 came up what is this and how much to fix


P1860 All GM - TCC (transmission Torque Converter Clutch) PWM Solenoid Circuit Electrical.
P1860 Description The Torque Converter Clutch Pulse Width Modulation (TCC PWM) solenoid valve controls the fluid acting on the converter clutch valve. The converter clutch valve controls the TCC application and release. The solenoid attaches to the control valve body within the transmission. The solenoid receives ignition voltage through circuit 239. The Powertrain Control Module (PCM) controls the solenoid by providing a ground path on circuit 418. Current flows through the solenoid coil according to the duty cycle (percentage of ON and OFF time). The TCC PWM solenoid valve provides a smooth engagement of the torque converter clutch by operating during a duty cycle percent of ON time.
When is the code detected? When the PCM detects a continuous open, short to ground or short to power in the TCC PWM solenoid valve circuit, then DTC P1860 sets. DTC P1860 is a type B DTC.

Possible causes - Faulty Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid
- Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid harness is open or shorted
- Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid circuit poor electrical connection. Unless you have a factory manual and very good auto repair skills this is best left to an expert. It is a messy dirty job that requires removing the parts inside the transmission for testing..

My 2004 chevy suburban is giving a code po740 and po743. I'm Redington that it may be the torque converter clutch circuit. Any thoughts? How difficult would it be to replace myself?


Not hard. If you have to do it on the ground, it is messy. You have to drop the transmission pan. Buy an internal harness, it comes the the TCC solenoid attached. On the passenger side remove the heat shield. Unplug the transmission control plug. Drop the pan, start at the back and work your way around both side. It will start leaking. Slowly remove the front 3 bolts, let the pan drain. don't remove them completely. At a point, push the pan back up and hold it, remove the last bolts, then dump the rest of the fluid. Remove the filter. Under the transmission control plug, there is a solenoid to remove to get it out. Remove the plug and a 8 mm bolt has to come off with a clip, then pull the solenoid out( don't loose them). Look at the harness and see how it is laid out. The TCC solenoid is in front. You have to remove another solenoid to get it out. It is held in with a clip. Look, you see it. Do not loose this clip. Reach up in the slot and pull the clip out( small screwdriver or pick), pull that solenoid out and remove the bolts holding the TCC solenoid. Pull the TCC solenoid out. Reinstall in the reverse order. This sounds like a lot of work. I do them in about 30 minutes on a lift.

2001 Saturn where is the transmission control solenoid


The TCC is located in the Transmission. You can gain access to the TCC or the Lock-Up Solenoid by removing the Transmission Pan and you will see 4 Solenoids there along with the 1/2, 2/3 and 3/4 Solenoids.

1998 saab 960 s po743


P0743 - Torque Converter Clutch Circuit Electrical
Symptoms - Engine Light ON (or Service Engine Soon Warning Light) Possible causes - Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted
- Low transmission fluid level
- Dirty transmission fluid
Tech notes This is an electrical problem code. Could be a problem to the harness to the TCC solenoid, the TCC solenoid connector or the TCC solenoid it self.

Dashboard message - service engine soon ?? my local service station said it said - torque converter


That is located in the transmission and can be very expensive to repair/replace - Do NOT take to Amco! Did he also tell you the exact electronic code? Uusally, the code will say more than just torque converter.

Have you noticed any hesitation when you are starting to move; in reverse on on a hill - any noticeable slipping?

Will not go in reverse, could it be transmission or transfer case?


gm transmission have known for transmission reverse drum failure or a sensor called tcc solenoid. For the reverse drum you have to remove the gearbox and it's an esxpensive fix and for the solenoid you just have to remove the tansmission pan and there are gonna be all the solenoids, look for the tcc solenoid and change it. The sensonr cost around $50. Hope this helps

Where is the tcc solenoid on a 1998 mazda mpv 2 wheel drive?


The TCC Solenoid is buried in the transmission, in the valve body. You need to take it to a transmission shop for a problem with the TCC Solenoid.

P1744 enginge code tcc solenoid circuit


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.

Tcc switch 1996 pontiac grand am


There are 4 solenoids in the transmission, they are all supplied 12V through a common pink wire, and grounded individually by the computer. There are two solenoids for the tcc, one is called the tcc application solenoid, the other is the tcc PWM (pulse width modulation) solenoid. I'm not positive, but I believe the PWM solenoid faciitates the smooth engagement and disengagement of the tcc, but the application solenoid controls the bulk of the hydraulic pressure. If you want to check the resistance of these solenoids, the application solenoid is grounded through the tan/black wire, so you should see aproximately 28 ohms resistance between the pink wire and the tan/blk wire as they go into the transmission. The tcc PWM solenoid should have a resistance of about 12 ohms and you would measure this between the pink wire and the brown wire. The transmission should be electrically disconnected when you do these tests.
