Needs a new torque converter. How much will this cost?

P0740 torque converter malfunction
Possible causes
Low or dirty transmission fluid
Faulty torque converter clutch solenoid valve
Torque converter clutch solenoid valve harness is open or shorted
Torque converter clutch solenoid valve circuit poor electrical connection

P0562 charging system voltage low
Possible causes
Low battery charge
Defective battery
Faulty alternator
Problem with belt
Open or shorted system voltage circuit

Not if the engine and suspension also need work. In some areas rust needs evaluation as well.

However if the rest of the vehicle is in reasonable shape, and you do not have money to burn on another ride (who does?) then I would go ahead. Keep the paper and if the vehicle dies too soon, you can resell the auto box.

420 is the catalytic converts. This needs check a bit further. They are costly. 741 tcc lock up for the torque converter. Do or get a transmission service first. Do the transmission first. then look at the cats.

I would venture that it's your torque converter solenoid. I am fairly certain that is what it is. You will need to look at the Haynes manual or a schematic of your car's transmission to see what it takes to get to it. Most cars, it's a fairly straight-forward operation. Cleanliness is paramount with extra care taken when removing the old gasket. I used a new, fine blade metal spatula and safety razor blade to clean the surface off as new. If any small bits of gasket get into any holes, you will need to remove them. I interconnected several plastic straws and the sucked the broken pieces out. With a piece of tissue over the end of the straw to keep from getting ATF in my mouth. It works fine. You should get a fault code reader to confirm my diagnosis. They aren't costly now and then you can clear the fault codes after you replace the torque converter solenoid. Hopefully, it's NOT the Torque Converter itself. These are costly. Good luck :)

drop off the cover under the torque converter and inspect the flex plate that the converter is bolted to. look for cracks in the plate around the bolts . undo the bolts and move the torque converter back towards the gear box and look for cracks around the flywheel bolts.. If all ok then do everything up and have a pressure test done on the transmission to check for internal mechanical failure. Have this done at an accredited auto transmission shop ( not the local mechanic) and as him what the results are and the possible solution. Remember to ask how much to fix the problem parts before you accept that it needs a new box

Hello looks like your looking at a toque converter this is in the bell housing located between the motor and transmission this is what converts the torque once these let go inside you loose your ability to move at all transmission needs to be removed and torque converter replaced

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.

Torque converter?
Catalytic Converter?

Catalytic converter:
Take vehicle to a local muffler shop (not a national chain). They will do a professional job and the cost is much lower than other places.

U have a problem with the electric transmission torque converter clutch, to repair this requires the removal of the transmission, and in most cases a new torque converter.

you sure its missing and not a torque converter shudder . as a auto tech some times its hard for me to tell the difference. it it was missing it would throw a miss fire code not a torque converter code at 126 k sounds the the trans needs to come out and a good tech needs to rebuild it
