For a few years, at least in my area, there was a issue with the tcc solenoid. It involved not only replacing the solenoid( dropping the pan and unbolting from the valve body) but also flashing or updating the control module.once both repairs are complete you should have no problems. A good dealer will help you out.

SOURCE: Trouble code P1740 on 1999 Dodge Ram 2500

I had the same code on my 2001 dodge 2500. The truck wouldn't shift from 3-4. I pulled the trans pan off and replaced a broken spring ($2.00). It is behind a thin plate with 3-4 small torq screws. You don't have to remove the valvebody. Only took me 45 minutes to fix.

I would like to give thanks to Jeff Russel from Teal automotive. He said this is a very common problem. He sells any part for any automatic Transmision and his prices are very affordable.
Here is a link to the website.

Hope this helps.

This code means that system to lean, bank 1.
some of the possible causes to make this code set are
1. intake or exhaust leak,
2. problem with the air system.
3. MAF (Mass Air Flow sensor)VAF sensor (Volume air flow sensor)
4. fuel pressure/pump
5. injector(s)
6. HO2S (Oxygen sensor)

SOURCE: i have 2 engine codes for a 2001 dodge ram 1500

I have never seen P0000 but P1740 is a standard autotrans code it should have another code with it,P1740 just tells you that the fault is in the automatic transmission.

SOURCE: what is this code P1404 on the dodge ram 1500 mean

That code is the EGR. I'd start by checking for a bad connection on the EGR plug-in. Pull the connector off and inspect each individual terminal inside the plug and the connector pins inside the EGR valve.
I found this solution at another forum on this issue. It worked on my 2001 Grand Am:

"Many GM built cars have a tendency to have the 'Check Engine Soon' light come on as a result of DTC code P1404. P1404 is described as EGR valve pintle stuck open, which in most cases is a false alarm. I had this happen with my '01 Grand Am. A little bit surfing on internet reveals that GM has a solution for the problem, a re-flash for the car's computer.

A software re-flash as a fix kind of indicates that the vehicles with this problem were built with it but I don't think GM will be re-flashing cars outside warranty for free. They will want their $100 for it.

Some hands on people I found had purchased a new EGR valve and changed it but the problem remained.

Possible reason (very likely) for the false P1404 code is that the plastic piston of the EGR valve position instrument (LVDT?) wears over time and starts reading a different position at valve closed than what it was when the EGR valve was first installed.

When the car was built and the computer circuits energized for the first time the computer learned the EGR valve closed position signal from the valve position instrument that is built on top of the valve itself. Over time, when the instrument wears, a slightly different signal is sent to the computer and when it differs enough from the 'Valve Closed Signal', that the computer had learned, the trouble code P1404 is set and the 'Service Engine Soon' light comes on.

Replacing the EGR valve with a new one does not necessarily fix this problem because the 'Valve Closed Signal' between valves is slightly different and it is just pure luck if your new valve would give a 'Valve Closed Signal' close enough to your original valve's signal not to set the trouble code. This is why the new EGR valve 'Valve Closed Signal' must be re-learned by the computer.

So, what this all means is that if the P1404 is a false code meaning that the valve pintle is not stuck open, then new 'Valve Closed Signal' can be re-learned by the computer using the old valve.

For fixing this problem the tool you need to have is a simple OBD II code scanner that can be used to erase trouble codes. There are many scanners of different price range on the market. I purchased one from AutoZone for about $90.

A code scanner is a very handy tool to have and I recommend everybody who is just slightly hands on type of a person to get one. It will end up saving a lot of money over time.

The fix goes like this:

1. Disconnect the wire harness from the EGR valve.

2. Turn key ON and erase the trouble code(s) from the car's computer AND TURN KEY OFF IMMEDIATELY WHEN THE SCANNER SAYS CODES HAVE BEEN ERASED. DO NOT TURN KEY ON BEFORE YOU RE-CONNECT EGR WIRE HARNESS.

3. Re-connect EGR wire harness and your problem should be fixed.

I learned this fix from OBDII.COM where carfixer and kozloski discussed it and I think kozloski was the one who provided the solution, so thanks to them.

There was also other people stating that this fix really works. Now I have joined this group of people as I got mine fixed using this trick also.

I believe erasing codes with wire harness disconnected and turning the key OFF right after P1404 code has been erased re-sets the 'Valve Close Position' reading in the computer and triggers computer to re-learn position next time the key is turned ON.

If you don't have an OBD II scanner and don't want to buy one some car part stores may erase the code for free, but if you have it done there you must tell them about turning the key OFF at the right moment. Other wise the re-learn process does not take place.

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.

Got a p1740 code, idot light went off when... 2001 ram 1500 sport


There was a Technical Service Bullitin (TSB) out(TSB21-11-00) for this problem. It applied to 00-01 trucks with a 46RE built before 08/01/00 It had to do with replacing a pressure boost valve cover in the trans. That was after only performing some tests with the DRBIII first to rule out trany wear causing the fault.
TSB's are written for the dealerships by their respective manufacturers. They usually cover a problem that has occured enough times under warranty to warrant giving the dealership a heads up on the problem and how to fix it.

Here is a link to the TSB I posted:

P1740 trouble code on a 2001 Dodge Ram 1500


There is one solenoid assy with two solenoids on it. One for the TCC and other for OD. in my experience, P1740 is caused by a couple of things. The torque converters are a subject of trouble for one - I always replace them - the other are the input sealing rings on the input shaft. Older designs leak pressure. Always replace with the plastic - **** end type which is the update today. P1740 has nothing to with the governor solenoid or sensor
