SOURCE: These codes comes out P0741

Your torque converter is not locking up.
The solution is to have the torque converter replaced and the transmission serviced.
Hopefully, you are still under warranty and can get it repaired it for free.
If not, it can get pretty expensive.

SOURCE: Torque Converter Clutch Circuit/Open

hello there

The problem is with the gear oil. To keep ahead of the rest BMW started what they call life time oil for their gear boxes, though that sounds great it doesn't really work in reality, they have now gone back to recommending a gear oil change every 60k miles.

In short you need to change your gear oil and soon, the oil in your gear box is no longer effective and will damage the gear box. You'll need about 5 litres for your car and costs around £15 a litre, expensive stuff!! I had the same problem with my 328i auto, the dealer was clueless and kept quoting the lifetime oil, I changed the oil and the problem has gone and it's so much smoother.

Hope this helps, please don't forget to rate me.

SOURCE: P0741 Torque Converter Clutch Circuit Performance

it's either the tcc solenoid inside the valve body not engaging or the converter itself is on it's way out probably due to bad seal.. change that also if you go the converter route..check also the ground to the solenoid and make sure it's getting enough voltage. make sure the fluid is up to date and flushed before all of the above. and remember after solenoid install car wont drive right for a few miles until computer picks up new solenoid or get new transmission installed

unfortunately this means you need to get yourself to a trusted transmission repair facility very quick. the torque convertor on your vehicle is not operating the way it should. this is going to be an expensive repair, i tell you this so your not suprised. but do your homework and find someone with a great reputation for their work. dont take your saab to just anyone. these cars can get really screwed up without the right people workin on it. the transmission will need to come out.

My 2007 dodge with 5.9 diesel is showing engine malfunction light and error code of P1740, failed TCC or overdrive solenoid. The truck seems to run ok in overdrive but I don't understand what the TCC...


Code P1740-Torque converter clutch did not lock up when the PCM sent the command. Enabling conditions: No engine or transmissions codes are present, vehicle speed was under 70 MPH, TPS was under 33% open. When the PCM commanded the torque converter to lock, no change was detected in engine speed. Blocking action: This code can block the following monitors: none.

Testing: Check torque converter solenoid for proper operation.

NUMBER: 21-11-00
GROUP: Transmissions
EFFECTIVE DATE: October 02, 2000
SUBJECT: 46RE Transmission MIL Due To DTC P1740 - TCC or OD Solenoid Performance
OVERVIEW: This bulletin involves the replacement of the transmission pressure boost valve cover plate.
MODELS: 2000 - 2001 (AB) Ram Van 2000 - 2001 (AN) Dakota 2000 - 2001 (BR/BE) Ram Truck 2000 - 2001 (DN) Durango

NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 46RE TRANSMISSION BUILT BEFORE AUGUST 01, 2000 (MDH O8O1XX).

SYMPTOM/CONDITION:
The customer may complain of a Malfunction Indicator Lamp (MIL) illumination. Upon further analysis, it is determined that the MIL is caused by Diagnostic Trouble Code (DTC) P1740 - Torque Converter Clutch (TCC) or overdrive solenoid Performance. Other than the MIL, the customer may not notice any other condition with the transmission.

This condition may be caused by an intermittent and momentary TCC disengagement condition. The transmission valve body pressure boost valve cover plate has been revised with a larger size orifice hole to address this condition.

NOTE: THE DRB III(R) MUST BE OPERATING AT RELEASE LEVEL 50.4 MDS2 SYSTEM CIS CD2067 OR HIGHER (AVAILABLE THE WEEK OF OCTOBER 2, 2000) IN ORDER TO PERFORM THE REVISED TORQUE CONVERTER CLUTCH STALL TEST. DO NOT USE EARLIER VERSION STALL TEST TO DETERMINE CONDITION OF THE TORQUE CONVERTER CLUTCH.

Yellow check engine light came on; code; P0741 refers to possible torque converter problem. car runs fine. what else could it be?


Audi code P0741 Torque Converter Clutch Circuit Performance or Stuck Off, THIS IS IN MOST CASES A STUCK TORQUE CONVERTER LOCK UP CLUTCH, U MAY NOT EVEN NOTICE THIS AS ALL GEARS WILL WORK JUST NO TORQUE CONVERTER LOCK UP, U WILL NEED TO VERIFY THE TORQUE CONVERTER CLUTCH CIRCUIT IS OK AND IF SO REPLACE THE TRANSMISSION TORQUE CONVERTER.
