First Time Tundra owner, Love it but has a Trans issue 2714

Recently purchased a 2008 Tundra 2wd,5.7L with 155K miles. Soon after 2714 code popped up along with the check engine and the VSC light flashing, was able to reset it and popped up a week or so later. I noticed when it came back on was under acceleration, had a shutter between gears, then was driving funny like it wasn't sure what gear to be in for about 1/2 mile. Shipped her over to Toyota and they said that code for solenoids means you need a new transmission for $5,700 and it will take 5 weeks to get it. Shipped her over to a transmission shop, they tore it apart and told me it needs a rebuild for $4,000. Took there word for it and had them do the work. Got it back and and twice now it has kicked off the same code for 2714, VSC, and check engine, I wanted to puke each time I saw the lights come on and both times had the same shutter under acceleration while trying to find a gear. She is going back to the trans shop tomorrow, reset the light and she drove home tonight just fine? but gather it will be back on shortly...figure one of two things either the trans wasn't done properly or worse to think that the trans has never been the issue?
Any thoughts would be much appreciated!

 

What was touched in the rebuild? was every thing replaced from torque converter to clutches to solenoids or did they just do clutches? the P2714 Shift solenoid code doesn't exactly mean the solenoid or Trans is bad (but to be clear it does sound like the replacement or full rebuild was need) all the electronics communicate through wire and connectors if that signal can't get to the other part the Computer will flag a fault at the part it can't communicate with or has a fault related there. So it could be issue up stream from the Shift solenoid that was the original culprit and driving on P2714 will destroy the clutches in the transmission which sounds like what happened.
Most likely what happened is either they just read the code and told you what it was or they ran the tests which would show it was bad and never bothered to check the actual connection at transmission since the transmission showed the signs being burnt out which would also trigger the P2714

 

I’m having similar symptoms with my 07 5.7L 4x4. I’m the original owner and it’s at 206K miles. My truck first went into limp mode on Christmas Day. I brought it in, had my mechanic clear the codes, and scheduled a transmission drain and refill. He said there was no metal shavings in it, the fluid was a little dark, but clean otherwise. I’ve been driving it since then with no CEL or limp mode. It’s definitely not driving right- it feels like it’s dropping into too low a gear too soon. There’s a slightly noticeable amount of resistance while coasting and slight loss of power up hills. Weird thing is, when I drive it in manual (or S), I can get through the gears just fine. What does that mean?

 

with out the DTC its hard to guess I have been scrolling a while now and haven't found any thing that stands outs. a Tech Stream device could figure out if there's any thing wrong by doing the test. As for the (S mode) it operates slightly different and uses different logic over regular (Drive Mode) same with (Tow Haul Mode) it uses a A.I calculated approach. but the fact it hasn't throw a DTC again tells me either it happened to fix it self (like maybe the dirty fluid confused a sensor ) or it was intermittent short that's just been lucky enough to not touch any thing else or the part failed in a such way that it gives of acceptable parameters so its not throwing a DTC

 

Thanks. Sounds like you already know, I’ll write it for everyone else- P2714 is Pressure control solenoid D performance or stuck off. My truck had a few other codes along with it:
P0761 Shift Solenoid C performance or stuck off.
P0894 Transmission component slipping
C1201 Engine/ EV control system fault
I don’t think I need a transmission replacement either, but how do you find the person that can accurately diagnose the problem? And after all that diagnosing, is the difference in cost that much more (plus the cost of not having my truck available for work)? Tough spot for sure.

 

I’m not trying to hijack your thread, but since we’re having the same problem, maybe both of us asking questions can get us a better answer. Good luck to both of us.

 

What kind of fluid did they pit in the trans?

 

He used the recommended Toyota fluid. My mechanic is good about that.

 

No Worries thanks for all the Help we can get...
My trans had what I was told a complete rebuild, new solenoids, clutch, and torque converter for about $4K.I wasn't present at the shop to have seen how the internal parts looked at tear down as the shop is an hour away, but I sure wish I could have been there for that moment...
The Truck Drove fine for about a Week then had that same shutter under acceleration and drove like it was searching for a gear and the dreaded lights come on(is this any variation of a limp mode?). I get the engine code 2714 with the solenoids but curious if its common for the VSC light to come on as well? I cleared the code and initially the check engine light went out but the VSC light didnt go out until I drove about a mile down the road?
The other odd thing is that once it gets through the initial episode I stop restart the car and it seems to drive just fine?

 

The next steps are going to be things like trying to measure the resistance of that particular solenoid on the TCM side of the harness to see if that looks correct, then possibly to try to manually command that solenoid in techstream or with a really fancy scan tool. For both of you, your transmission may have been totally OK and you just have a wiring issue to chase. It's also not impossible that the TCM is suspect. If the solenoid resistance appears at the TCM connector as it should but the TCM does not appear to be able to actuate it, then the TCM would be a bit suspect.

 

Thank you for that. Hopefully I can find someone to trace that path for me. Replacing the entire transmission is really a last resort. I suspected a wiring problem from the beginning. I’ll post what I find out.

 

Thanks for the info! any thoughts on the VSC light that comes on in tandem with the check engine light?
Truck is at the shop currently, will post any updates...

 

The other lights are coming on because of the other issue. They don't mean much on their own.

 

Give John a call at IPT Transmission. He was a great help to me when I had a shudder in my truck. They are in New Jersey pretty much experts in this stuff.

 

That's a normal Tundra trait. All my life I've driven domestic automatics and they seem to "freewheel" when coasting. When I bought my Tundra I noticed it doesn't. It'll even downshift a gear if brakes are applied coasting downhill. A built in "jakebrake" if you please..

 

I love the “jakebrake” in Tennessee my V6 downshifts automatically makes some cool noises with the dual exhaust. Never realized it wasn’t normal until I drove my friends 4.3 Silverado. Very different trucks that’s for sure but I’ll stay with my Yotas!

 

No, this resistance is something different. I’ve been driving this truck for the last 14 years, and what I’m experiencing is definitely related to the problem. It’s akin to being in too high a gear when needing to accelerate slightly with a manual transmission. Which, I’m sure, is exactly what the issue is- it won’t shift at the right moment. Interestingly though, if I put the pedal down a bit more, it will downshift and drive right. If I accelerate quickly from a stop, it doesn’t lag or drag at all. All the power is still there when the RPMs stay high.

 

10-4, understand. Good luck getting it back to 100%

 

Well I got the Truck back from the transmission shop on Thursday, not sure what they did this time? but the truck drove great for that day the next morning drove about 1/2 mile and noticed she wasn't shifting on from 3rd gear? just went and went in that same gear. I stopped turned the Truck off, let her warm up for a minute and drove fine after that. Then had the exact problem this morning getting stuck in 3rd gear except this time it kicked off the check engine/vsc/ and skip lights. Didnt get to pull the codes as I just drove her to my mechanic and left her...pretty frustrated as this is the third time going back after the rebuild...

 

Welcome from NY.

 

Welcome from LA (Lower Alabama)! If it turns out to be something much less than the tranny, I would have a serious discussion the the tranny shop owner.

 

Hope the OP and others with this issue are still on.
Did either of you change anything electrical prior to this happening?
I recently replaced my battery and head unit on my 2011. The next drive, P2714 appeared. It's a long shot, just asking.
