Lexus GS 2013+ :: 2015 Shift Solenoid / Torque Converter Code Appeared
May 14, 2015
I picked up a 2015 gs350 f sport in atomic silver / black. I'm excited to pull out of the parking lot and get on the road! Yeah, not so much. As I take a turn onto the road I notice it's very sluggish, like starting off in third gear sluggish. I eventually get up to speed and wander if the floor mat is stuck under the pedal or something, whatever. anything but the car is broken.
I eventually get up to speed. Everything is fine. I don't accelerate hard because the the car only has 12 miles on it. Otherwise it drives like it should. Off the freeway and at a stoplight with an incline. Start to go, same thing. I pull over, turn the ignition off and back on. Car is fine.
So later that night (43 miles on the ODO) CEL and Trac off lights up. Car will not get up over third gear. Make it another 2 miles home and park it. I'm pretty distraught.
Took it to the dealership, don't know what they are but 2 fault codes came up. One for a shift solenoid and another having to do with the torque converter. Under 100 miles on the ODO!
So I'm with a red ES loaner car. Never seen it on a brand new car.

I have a 1997 Dodge Avenger ES that reads code P0743 Torque Converter Clutch Solenoid. I've replaced the transmission control module, and filter. I've called the Dodge dealership and asked if the new transmission control module needs to be programmed. The service department said "Possibly" I said "Well it's shifting better than before. If there wasn't any firmware on it what would it do?" He said "My guess it that the car wouldn't shift." I asked if the Torque Converter Clutch Solenoid visible once you remove the filter. He said "I'm not sure." Clearly, my car isn't going there. Then asked to be transfer to the Parts department to see if there was a part called Torque converter clutch solenoid. That answer was "No" there isn't a part listed called "Torque Converter Clutch Solenoid". What should I do or try?

How can I fix the P0741 engine code? Vehicle has 100k mileage.
Some of the on and off symptoms: loss of power, doesn't go over 40mph on the bridge, rpm dramatically goes high at low speed, lower mpg.
I did a tune-up: [URL] .... 2Bplugs, engine, coolant, [URL] .... 2Bfluid, steering, ignition coils, short ram intake filter cleaned.

Where is the plug on the transmission to disconnect the TCC solenoid? I am trying to diagnose a lockup issue and need to disable the clutch from engaging for a test run.

I recently purchased this truck so I don't have any history on it. It's the V10 motor, automatic, 4 wheel drive, with a crew cab. I took it to Advance Auto to have them read codes and it came back with torque converter solenoid fault and 2 other codes related to that part. I didn't get to see the actual code numbers.
I've talked to 2 transmission shops and they said they could throw a solenoid pack into it, but that it might not even fix it. The truck drives fine, shifts fine, the tranny oil looks and smells fine, so I'm tempted to not worry about it until something else happens.
The truck has 217,000 miles on it...

I bought the car with 117k and never since my possession bothered to service it. Why? I kept putting it off well at 165k I said heck ill do it. Currently at 170k my gear wont shift past third and its reoccurring almost daily. When I first bought it it was intermittent. I think the late service messed it up. Here's the thing, aamco will open up my pan and look at my solenoids which is 250ish.

The problem is that it appears the torque converter is locking up so early even right after getting into second gear at speeds between 20km/h and 40km/h. This causes shuddering/rattling coming from under the hood. If I am not mistaken a torque converter should lock up at speeds 80km/h+. I've never seen this behavior on any car before. I'm not sure what kind of damage is being done either by all this shuddering and rattling going on with the transmission. I feel that this should be something that needs to be addressed via some software update. Is there any software update in regards to this issue?

I have a 2007 Sonata, performs flawlessly, my wife's 2011 Elantra, not so much. We've had issues with her car from the get-go. The Elantra has 32k miles on it. About 15k miles ago the dealership reprogrammed the transmission. Problem seemed to be fixed, to a degree. Hiccup here and there.
Last night when my wife came home from work she said it was shifting hard. I just shrugged it off. We came in to town, about 5 miles down a busy highway. 55mph, no problems.
Car sat for a couple hours. We got in the car to come home, buttery smooth first few shifts to 35 mph. Car had probably been running about 5 minutes. Pulled out onto highway, shifts 1-2 fine, 2-3 holds about 2500 rpms, won't shift, won't shift, BAM! repeat 3-4, and I believe 4-5. I was so shaken up I didn't count. I pulled off and took the back road and it continued to do it for about 3 miles. It almost feels like the torque converter is locking up. Someone mentioned a transmission temperature sensor, but that is only in Sonata's, no one has seen it in an Elantra.
By the time we got home, the car was shifting normal. This morning I get in it because now my wife won't drive it, and it works fine. Works fine all day.
Go into dealership, they say everything is fine, they called Hyundai, they say nothing wrong, come back when you have a problem.

I have an issue to where every once in a while my truck will not shift and when it does shift it slams into gear, and my overdrive light flashes and then I'll turn the truck off let it sit and crank it back up and it drives fine and the overdrive light is off. It shifts normal and smooth other than when this happens. Not sure if it is my torque converter or maybe a solenoid or what. My truck is an 07 f250 6.0 with 192,000.

My girlfriend's 2001 cavalier has about 160k on it and about a week ago it started shifting harshly accelerating to highway speeds and the CEL came on along with the traction control/abs warning light. I pulled the OBD2 code and it was P0742, Torque Converter Clutch Circuit Stuck On. We took it to the transmission shop down the street the next day and they wanted $600 to diagnose. We called 'shenanigans' and decided she should take it to her regular shop. On the drive over the transmission shifted normally. Both shops noticed that the transmission cooler lines were rusty and seeping, but neither thought it was the cause of the problem. The shifting issue hasn't recurred even after a couple hundred miles during the week. She hasn't had the transmission fluid changed and doesn't know if it had been when she bought it about 80k miles ago. It seems to me that pre-emptively draining the fluid, changing the filter and refilling, especially to check for debris in the fluid, would make sense, especially if it was debris jamming the circuit that caused the error code in the first place.

I am getting a single code - P0753 that comes on now and the van will not shit into 4th gear. It re-appears after clearing the check engine codes in 5 seconds. That seems to be the "A" or 1-2 shift soleniods (or wiring).
Can you get to the shift solenoids after dropping the transmission oil pan or do you have to pull off the side housing cover - that seems like a much more difficult job?
Of course, I will replace both of the solenoids if I can get to them. I will do it myself if I can get to them after dropping the pan but don't know if I will be able if that side cover has to come off.
What is the location and if I should be able to get that drivers side cover off if that is where they are?
I think the 1998 Venture's tranny is the 4T60-E.
I have a 1000+ mile road trip coming up soon so I got to get this fixed shortly. I guess I am glad this didn't happen in the middle of the trip though.

I'm trying to find information about replacing solenoid in my transmission. I have pdf of repair manual, and it doesn't have much information regarding transmission.
I have a p0766 code, and I think I need to replace Shift Solenoid. Does Technical Information Service Cover this with subscription.

Code P7081
Do I have to drop the valve body to get to the shift solenoid? Is there only one solenoid? Anything special or tricky I should know about?

I have a 98 camry with code p0755 - shift solenoid valve#2 malfunction.-What are some of the most common causes. How to test it ,the issues that cause this and what to do also after replacing it if bad? Also are these to be replaced in pairs with both 1st -2nd shift and 2nd to 3rd shift .
If I have high miles on it will adding the 2 -3 quarts of new fluid give me issues as to mixing with the old and part breaking up in transmission(I've heard a lot happens when u replace very old fluid with new or flush it fully)..will be replacing filter also but not the rest of fluid still in transmission at this time. Looking for a link a pic. of the exact location on transmission inside pan .of it(looks similar to other shift solenoid near it )...

My old 97 f-150's 4R70W started slipping.....so I just installed a rebuilt 98 f-150 unit that had about 10,000 miles on it and also has a transgo shift kit. Got it finished today....and.....
I have an check engine light code p0750 "shift solenoid A malfunction"........when leaving from a stop in Drive, the truck starts going in 2nd gear and just skips 1st gear all together. If I manually shift it, then 1st works fine and shifts through all the gears fine.
But in Drive.. it skips 1st. What to do? or what could be the problem? Where is this solenoid? Can I swap the one out of my old tranny into this one without pulling the whole tranny apart? (I don't mind dropping the pan though...) Or could i have a bad connection somewhere maybe?
Also....When the tranny shifts from 2nd to 3rd the rpms jump about 500 rpm before they drop...kind of seems excessive. Could this be caused by the shift solenoid A malfunction?

I just bought my car a few weeks back in July. I noticed that the seats appeared to be hotter with the A/C on. It turned out, I was right. With the seat heaters OFF and A/C ON, the seats would get hot.
I've posted an infrared video here .... Infrared showing seats of 2015 Lexus IS350 F-Sport - YouTube
For reference, I also made a video of normal heating (e.g., seat heat ON) ... Infrared of normal seat heating - 2015 Lexis IS350 F-Sport - YouTube
And you can see that the heating areas are different.
The dealer says this isn't happening. 2015 IS350 F-Sport

I have two codes P0760 and P0755, malfunction shift solenoid B and C, today I took it to Hyundai here in queens ny, I was told that It would cost e 2684.00 to fix my issue, I can't believe that if those two codes are the problem why would it cost 2684.00 ? Where are these solenoids located?
The car feels like your one of the flintstones, it's stuck in 3rd gear and cant get out, then it jerks when it tries to shift, tranny oil is fine not burnt like if the clutches are gone.

2005 Ford F250 4x4 XL 5.4L 5R110W WITH 177,600 MILES... Tow Haul light flashed after 78 miles (along with other codes) after purchased. I purchased it used. While driving transmission would stop pulling as if it went into neutral and slam back into gear, at same time Tow Haul light be flashing...
Code is P0760 shift solenoid #3, I read from the forums on the site one caused could be the ground wire. We installed a ground strap from battery to tranny
Still does the same.
I have a shift solenoid ordered if needed, knowing the location of #3 solenoid in the tranny is the key to not having to keep dropping the pan. I love this site and have been reading it for long time.
