P1740 Dodge Code - Torque Converter Clutch or Overdrive Solenoid Performance Condition

I REPLACED THE P1740 OR TCC SELOINOID AND code came right back... now the mechanic is saying to replace the torque converter ????? truck seems to shift fine to me ??? is he guesssing now or do i need to replace torque converter ???? thank you 2001 dodge ram tk 1500 5.2 motor 2 wd

Get a second opinion. If the truck is shifting OK, then the scanner may not be reading the code properly. Dodge have a service bulletin for the P1740 code problem, the bulletin suggest that a scanner could show the P1740 even if there is no problem with the transmission.

I have a 2000 dodge ram 3500 van and code p1740 came up. the van doesnot want to drive in any gear as if the transmission wasn't there

After replacing my transmission and torque converter I started getting the P1740 code. A friend of mine changed his engine a few months ago and since then he is getting the same code.

TV CABLE. The transmission fluid pressure needs reset. SET TV CABLE TO WOP (WIDE OPEN THROTTLE) BY HAND UNDER HOOD (NOT CAB VIA GAS PEDAL) THEN LOCK TV CABLE. DRIVE SLOW THRU 1st and 2nd gear then punch it (WOT) and not rpm redline out before transmission kickdown. AFTER TEST DRIVE MOVE TV CABLE OUT OR IN DEPENDING ON FIRMER SHIFTS OR SOFTER. ONLY MOVE IN SINGLE CLICKS. 1/4of an inch is to much. TOO MUCH ONE WAY WILL CAUSE SLIPPAGE.

My check engine light came on with the code p1757 and p1740. Is it safe to drive it back gome? Im less than a mile from home..

Yes, safe to drive.

Thank you! I didnt want to drive it and cause more problems anf more expensive fix

One of the transmission solenoids probably got stuck. Make sure the transmission fluid level is OK.

I get a P1740 only in the winter time. 2000 dodge van 1500.

Have you change the transmission fluid since the problem start happening?

I had a P1740 code that came on periodically after a reset. usually 100 to 150 miles later. Shifting was erratic. Would have to nail the throttle at times to get it to go to second gear then would shift very firmly. Any deceleration and it would downshift very hard. Was researching it and trying to find answers. A youtube video said to try the TPS (Throttle Position Sensor) Which I did and my old one was obviously bad as it rattled inside. It didn't fix it but it did seem to help. The problem was less frequent. I tried many other things along the way and I was due for an emissions test so I stopped and aired up the tires for whatever reason. And believe it or not, it's been 105 miles and no crazy shifting at all. I couldn't get more than 5 or 6 miles before when it happened. I have to believe it was somehow related to the rear axle speed sensor screwing with the computer. I honestly have no clue but it fixed it and I am thrilled. The TPS was about $25 and the air was free. Crazy I know but hey, it shifts perfect time after time.

Before I go replacing this $102 part here's my dilemma, 2000 dodge RAM 5.2L 4x4 . With only prior too the light and code read out of P1740 there was no prior signs of transmission probs it shifted fine and operated like it's suppose to and the tranny fluid was clean and at the proper fill level, I believe in preminative maintenance, so with that in mind one faithful day I was driving down the road and all of a sudden it was like I had no transmission RPMS went through the roof as my truck slowed down. Let it sit for a few mins and fired it back up only to drive it for about 1/8th of a mile and the same thing would happen. I'm kinda confused bc every post I've read on the P1740 code no one mentioned there's doing the same as mine is! I'd really like to pin point this issue for what it is instead of buying& $1,000 of dollars worth of parts that's not gonna fix the issue, plus I ain't got $1,000 to waste on it. Please it you know exactly what I can do to fix the RAM may God bless you.

What was the issue? I'm in that same boat right now!

Is tough to tell you exactly what the problem is, every vehicle condition is different. There is a factory service bulletin that recommends replacing the Torque Converter Clutch (TCC) and Overdrive (OD) Solenoid, but if there are no driveability issues. In your case, due to the driveability problems and the age of your vehicle, my only recommendation is to have a transmission shop perform an inspection

I appreciate your advice man. I figured I'd go with the O.D Solenoid and if by chance that isn't the issue I can always return it.

Put in a new od solenoid and new code came up for the PCM? WHAT went wrong? If it was the PCM to begin with wouldn't that come up first?

What is the code number? besides the code, any other driveabilty problems?

Yeah same as before, it's like there's no gears, I did a lot of research on the code"I'll have to get that code and edit to this message, but it's leaning towards the shift solenoid or the pump orrrr the filter and or the PCM. MY fluid before hand was was still clean looking but had an off smell to it and the day after my OD wouldn't turn off by the switch my trans temp light came on and it smelt as if the tranny fluid was hot... Now in neutral it makes a metal grinding type noise not to loud and quiets down after a few mins but in D or 1,2 it doesn't make a sound.

I just bought a 2000 dodge ram 1500 v8 magnum and my check engine light came on. I took it to AutoZone and the code p1740 ppped up and he said it was the torque converter clutch solenoid then I took it today now he is saying that its the transmission control module. is it the same thing or is it 2 differnet things? Im onfused

Two different things. The torque converter clutch solenoid is inside the transmission, you probably have to replace the torque converter clutch solenoid to fix the problem. I don't think the problem is the Transmission Control Module (TCM).

How did this resolve for you. I have the exact same problem! Jason Liske

okay, so I have a 2001 ram 1500 with a 5.9 and 46re trans. truck has 55k miles and fresh fluid and filter about 10k miles ago. just recently it started intermittently jerking to shift, I think into 2nd gear (not 100% on the gear but I now it's low gear) especially uphill. and I got the p1740 code and can't find any of the same symptoms online. help!

Even if you replace the fluid 10K miles ago, start by checking the transmission fluid level and condition. If the fluid it's already dark and smells burnt, then you may have a mechanical problem.

that was the first thing i did... still full, pink and fresh

According to a national database of repairs, other than the transmission fluid and filter, the Torque Converter Clutch (TCC) Solenoid is the most likely cause of the problem.

I have a 2000 dodge ram 1500 5.9 4x4. I had the transmission rebuilt almost 2 years ago. I dont drive it much. I put on less then 10,000 miles since rebuild. Now they told me they upgraded the shift solenoid because my problem was the TC tire up and kept clogging the sensors. Now some times if I get on it to pass someone the gears slip witch is kinda weird maybe I thought it was just too much on the tranny. It drives and shifts good. If I drive it to work witch is 30 miles. Sometimes it throws the p1740 code. Not all the time. I usually clear it and keep going. That has been happening about 5 or 6 time in last year. Now the transmission is out of warranty. But my question is could a bad ground or electrical connections cause this code to be thrown? I see some weird stuff sometimes that is why I ask. Like the window wont roll up one time or the door looks wont look at the switch a few times I have tried to clean the ground connections but I see a big rust problem with these trucks. So could there be nothing wrong and an electrical problem throw the code? Thank you for your time

I haven't seen an electrical problem setting the P1740 code. So did they did any repairs since the the transmission was rebuilt? there is a factory service bulletin that recommends replacing the transmission valve body pressure boost valve cover plate. The cover plate has been revised with a larger size orifice hole to address this condition.

They haven't done anything to it since the rebuild. I did go out and talk to them a couple of times after the rebuild and the mechanic was the one that told me about the valve body pressure boost valve cover plate how it was recommended to enlarge the holes and he did that when he was rebuilding it. One of the reasons I went out to them was about the first time the code was thrown and they drove it and hooked up their scanning equipment to it and it was showing a system charging problem. Found out my alternator was bad and I replaced it. Later after the code reset it never came up again until months later. Past the warranty stage. Like I was saying before everything operates good just every few months the code comes up and wasnt sure if it could be from electrical problems rather than mechanical. Thanks

I have a 2003 Dodge Dakota 3.9 Liter, 2 wheel drive. My Check engine Light came on. I cycled the ignition 3 times without starting it each time. Up where the odometer reading is came a code P 1740 then P done. My truck has an internal code reader. I am hearing a lot of things about this Code specific to Dodge. It seems to be all over the spectrum it seems to happen in all different types of Trans and engine combinations. So my question if you are getting this code in a 4 X 4 Ram 1500 with a 5 .9 Liter then we can not have the same trans. What is the common link here?? I am thinking it's some type of electrical switch. As my Trans has never shifted worth a crap form the time I bought it and I didn't get any code 3 weeks after I bought it brand new and it wasn't shifting correctly. So what cheap ass part did they hook up to all these different Transmissions that has been failing in each Truck??

According to the factory service manual for your model and year the P1740 means: Torque Converter Clutch or Overdrive Solenoid Performance Condition, which means that the control unit has detected a problem with the Torque Converter Clutch (TCC) Solenoid. If the problem persist, then may have to replace the Torque Converter.
