Welcome! Derf knows all about 08 Vue transmissions. There are several issues.

When a solenoid starts to fail whichever gear or gears that solenoid controls does not work correctly. So if the soenoid for second and fourth goes bad only first and third will work properly.

I owned a 2008 Vue XR for 100 K. Experienced the 35R waveplate failure, which shows itself as shift flares (where you get to the rpms where an upward shift would normally occur between gears, and instead of shifting smoothly, the rpms will increase as the current ger disengages until the moving parts for the next gear get fully into place (so to speak) and take over as the next gear of the tranny to propel the vehicle..You get the increase in RPM because the timing of the gear change is not right.

This can happen for multiple reasons. It does not only occur in the 35R failure, though this is a known issue where the flare occurs on the 3-4 5-6 shift and the shift into reverse (or the loss of reverse). GM had extended warranty coverage for it.

A malfunctioning transmission solenoid could theoretically cause similar behavior in different gears as it may not be actuating completely, messing up the timing of one or more of the gear changes for which it is involved in

I recently took ownership of a 2008 Vue from my sister in law. In August 2017 the transmission was repaired under warranty for the 35R Wave Plate. Less than 1000 miles are on the repair. Yesterday while driving to work while on the highway there was a hard shift. Afterwards the transmission did not seem to want to up-shift. Upon arriving at work I was unable to back into my parking space as it would not shift into reverse. Got the car to the dealer that did the original repair to diagnose. They have indicated that the transmission again needs repair, but the failure was caused by an electrical issue. As the electrical issue was the cause, the current repair is not under warranty. They have estimated $4,500 - $5000 to repair as the electrical issue will need to be identified once the transmission is repaired. I'm trying to understand how an electrical issue would cause the spontaneous catastrophic mechanical failure. Is that even possible or is the dealer trying to get out of performing a warranty repair?

I call BS.

The TCM transmission control Module will very likely have the trouble code stored right now.
And since they had to replace the 35R waveplate, and there is now an "electrical problem" preventing reverse from engaging, by definition they would have been messing with all kinds of internal connections that may exist.
The dealer is basically saying "I fixed the 35R issue, but there's no way your issue could POSSIBLY be related to our rather major dismantling of your whole transmission.

Now in the spirit of fairness, it could be a shift solenoid or line pressure issue in the valve body. I THINK that is internal to the transmission, but it's not going to cost 4K to get at it (disassemble tranny/fix/reassemble tranny)
If it is, then I would agree it is not associated with the 35R repair.

I also take issue with a price quote of $4K to fix a supposedly as yet undiagnosed problem. They are likely subbing it out to a local tranny shop that will diag it in 10 min or less.
$4K is about what it costs to do the 35R repair, most of which is labor disassembling to get to the waveplate, replacing it, and reassembling everything.

funny how the quote is right around the cost of a 35R repair......

Run, do not walk, from this dealer. You are being played for a fool.

Following up after a quick conversation with the service rep he is trying to get more info from the tech. All he could tell me at this time was that there were two codes P2724 & P0700. So I'm off to research those two codes.

Just spoke with the tech. He said the TCM commanded 2 solenoid to activate at the same time and that caused the clutch plates to weld together. After questioning, he said he could take care of the labor, but the parts including a new TCm would be $1,200 plus tax.

Heading in the right direction, but still not sure if we want to proceed or cut our losses.

P0700 is the code that sets when the transmission is telling the ECM "I have stored trouble codes" standard when tranny has codes

P2724 - Pressure Control Solenoid 'E' Stuck On (E or "5")

The Pressure Control (PC) Solenoid Valve is an electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As current flow is increased, the magnetic field produced by the coil moves the solenoid’s plunger further away from the exhaust port. Opening the exhaust port decreases the output fluid pressure regulated by the PC solenoid valve, which ultimately decreases line pressure. The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).

Sounds like, based on the codes, the line pressure solenoid is stuck "on", which, per the above description, means the line pressure is lower than it needs to be for proper operation.

This is completely consistent, as I understand it, with not being able to shift into reverse on most automatic transmissions, as this requires a higher line pressure than is required for the forward gears.
That being said, you need ONE solenoid replaced. If not replaceable individually, you would need a new solenoid pack. If solenoid pack is integrated into the valve body you may need to replace the valve body, but I doubt that.
RESEARCH WHICH ONE OF THE ABOVE IS CORRECT. Your wallet depends on it.
Why you would need a new TCM is beyond me, since the TCM shows no signs of any clutch related errors caused by moving two clutch plates at once.


As for "clutch plates welding together? That is incredibly creative boil sheet. Funny, the rest of the gears are fine, no?
That'd be impossible with those two damn welded clutch plates not letting anything move freely in there.

The dude is just trying to get some $$ back towards the 35R repair, because GM is paying him less than the tranny shop is charging him. No dealer will spot you labor. That's where the money is. He's trying to profit off parts you don't need and will likely put in his parts inventory, not in your trans, then you pay him 1500 for a solenoid that costs, under $100.

Oh look --- 2008 Vue XE V6 Pressure control solenoid!!! https://www.rockauto.com/en/catalog/saturn,2008,vue,3.6l+v6,1440279,transmission-automatic,pressure+control+(epc)+solenoid,17897 (this link will not open the pressure control solenoid sub window, but you can find it in the list on the left)
Pressure Control Solenoid$52.79

Ignorance is NOT bliss.

(Not calling you ignorant -- pointing out that lack of knowledge of anything can cost you thousands of dollars more than it needs to.)
It is admirable that you are taking the time to learn what you need to in order to keep from getting cheated by unscrupulous people.

WALK AWAY.

Research what will be needed partswise to get the new Solenoid. Get some recommendations for some local tranny shops in your area from people with first-hand interactions. There are plenty of honest mechanics and transmission specialists out there -- the difficulty is figuring out which ones they are.

Just my two cents, I had a similar sounding issue at about 110k miles and was able to get the tranny repaired under the extended warranty for the the waveplate problem.
