This code usually comes on when you have a bad tourque convertor solonoid problem, not the tourque convertor itself. You may notice it when the car is running and you come to a stop or when you are taking off a lot of times it feels like a dead spot in the transmission.

Good Luck and I hope this helps you. Allen

Is it necessary to drain torque convertor on


For routine services this is virtually never done. Just the oil in the pan is changed. It can be done , and normally costs a lot in fluid to flush the convertor. I had to do this once when getting my Toyota trans serviced at half the recommended miles and finding the fluid black. I now to normal more frequent services.

How to drain and fill transmission fluid in 2012 chevy malibu?


GET NEW GASKET AND FILTER FOR TRANNY ALONG WITH THE FLUID (BEFORE YOU BEGINE)
GET A LARGE FLAT DRAIN PAN.
PUT CAR UP ON 4 JACK STANDS.
place drain pan under tranny pan.
undo tranny pan screws - allow one corner to hang lower than the other corner (to allow fluid to drain) slowly remove them all.
Its messy! empty tranny pan into drain pan. set tranny pan to the side. undo the filter clamp, carefully remove the filter - set into the drain pan, remove the gasket around the tranny body/tranny pan.
Clean tranny block surface with clean cloth. install new filter, install clamp tightly. Clean tranny pan, place gasket onto pan and then reinstall tranny pan. (this only change the fluid in the tranny body and pan) If you wan the fluid out of the torque convertor you have pull the pan under the torque convertor and turn the convertor so you can get at the drain plug. Allow fluid to drain into drain pan. Reinstall drain plug and pan. (you will need a lot of fluid) Check manual for qty. Place car back on to ground/floor. Refill tranny through filler tube. Do not start the engine until oil is at full mark, and when you do start it do not all it to run for than 4 minutes - stop and add more fluid and check full mark again (repeat until no longer sinks below full mark. gently test drive around you block -- come back and check level while engine running. Top up if needed.
Siphon out excess above full mark. Test drive around 3 block,
come back check full mark. Because the torque convertor was emptied it can take a while to get all the air out it.

My Ford Focus 2006 4 cyc has an engine code PO741 on my OB2. What does that mean?


P0741 Torque convertor clutch circuit failure,it is located in the transmission valvle body, it is attatch to the valve body you can remove it seperately as long as your going to own the Ford focus you might as well get use to replacing these all the time,very common transmission issue with todays car. By the way it is sensitive to worn transmission fluid,when you dont service often these are suspectable to failure.

My check engine light was on and the transmission acts like it doesnt wanna shift. i had it scaned to see what codes it was throwin and they said that it was the transmission torque converter stuck on.. Am...


You will need to take it to a shop to have your torque convertor solenoid and circuit checked.The torque convertor solenoid has a ball ans seat in it and the ball gets stuck at times and lets your convertor stay engaged. the solenoid shouldn't be more than 50.00 and about 2-3 hrs labor cost,plus top off trans mission fluid.

Transmission light cod P0740


PO740 is a TCC/lockup code.TCC stands for Torque Convertor Clutch.In between the engine and transmission is a torque convertor.Inside the torque convertor is a clutch.This clutch engages to eliminate slippage inside the torque convertor.When a malfunction occurs in the system,which is activated by solenoids,and a computer,a TCC code will set.There is a diagnostic route specifically for that code,to determine if the malfunction is electrical,mechanical,or hydraulic.

Vibration in 1998 town car


The transmission in your car is the 4R70W model,and i've rebuilt hundreds of them through the decades,and the vibration you are likely feeling is in the torque convertor.I call it the "washboard effect",or at least that's what it feels like,running over an old timey washboard,and it can also be described as a shuddering sensation,or chattering.Inside the torque convertor is a clutch that engages to eliminate fluid slippage within the convertor,thus making it more efficient,resulting in better fuel mileage.This clutch becomes weak and slips,and that is what is felt.In most cases,the vibration is felt at speeds of 40 mph and higher.Ford and Lincoln dealers have a Technical Service Bulletin (TSB) out about this,and they advise changing the fluid by dropping the pan,and pulling the drain plug in the torque convertor,changing the fluid to a Ford specification fluid,and adding a highly friction modified supplement to the fluid to prevent the washboarding.In most cases,it solves the problem,but in some cases the torque convertor must be replaced.Good luck
