Toyota Sienna 2011 - Transmission issue??

I have same issue with 2012 awd. Any suggestions?

Any suggestions on what is wrong? Seems as though they are all about remove and replace at Toyota as opposed to fixing. This mentality drives me nuts. The tranny can't be all bad being so new, I have to replace the whole tranny with a factory "rebuilt" for $5000+ so you can replace a cheap $100 sensor or solenoid in my old one and sell it to the next guy as rebuilt for $5,000+. "Its a Sealed transmission requires no maintenance" says Toyota Dealership. What a scam, Toyota sure has changed in the 2000s, figured out they were missing out on all that sweet, sweet repair cost money Ford and General Motors have always enjoyed! Jerks.

We have a 2011 and now it's 2018 with just under 40k miles. It needs a new transmission already. So sorry that I got a Toyota.

I just had the same issue with a 2012 AWD Sienna as well. At 77K this Toyota says I need to replace the transmission with a 'reman' for $6000 due to an 'internal component failure in the transmission' out of warranty. To Debrand, Cshells, and Joell, please call Toyota Corporate Customer Service at 800-331-4331 and relay your experience if you have not already done so. When I called, they 'logged' my concern and said that Toyota 'declined' to take any further action as they did not have a 'trend' of other logged concerns from customers with transmission issues for this vehicle.

Yesterday I just experienced the same issue on my 2011 AWD with 96K miles. Engine OK but Transmission not responding. When shifting in drive or reverse moved for a few seconds and stopped moving with no check engine light on. This morning before towing the car to the dealer turned on the engine and same situation with only difference being the Check Engine and AWD lights on. I took it to the dealer and they said the transmission is blown out. They confirmed that there is no transmission leak and said some mechanical failure inside and can only replace transmission. I called the corporate customer service to make sure the report is logged in. I have been driving only Toyota and Lexus over last 30 years and usually keep them until they break. This is the first time I experienced a transmission failure. No other issue with my other cars. This is very disappointing ....

I had the same problem today. I was told by the repair shop that the transmission computer quit working correctly and has been shifting my car into the wrong gear as I drive, without me being aware of it. Because of this, the entire transmission is destroyed and needs to be rebuilt. $1,000 for the new computer and $4,500 for rebuilding the transmission.

I need to replace transmission too but mine are over 170k

I have a 2012 Toyota Sienna AWD and the second transmission went out needing a third. Same symptoms as original post. No warnings only a squeal for a split second and then loss of power to the wheels. First trans bad at 50,000 (Toyota replaced) Second trans bad at 80,000 (Toyota only warranties 1 yr it’s been 2yrs. They aren’t covering the second, offering to split the costs). 1-800 corporate customer service not returning calls. Toyota is no longer the company that made its name.

Second transmission replacement this week on my fleet of Siennas and third within one year. the three Siennas were either just under or over 100k miles. We do not put too many miles on these vans as they are only used to transport children to and from school. Two trans. jobs on '14 models and today's trans job is on a'13. All FWD. As a fleet owner, I made a decision to pay more for Toyota for its reputation in reliability. Sad to say this brand is not what it used to be. After taking this sienna to 3 different Toyota stealerships in my area, they all refuse to diagnose the transmission because there are no codes. Third gear slips, red lines before going into fourth. If gentle on the throttle, will shift smoothly. Tried to catch the problem early on before it gets worse. No dealership would diagnose. Said because there are no codes, they cannot touch the transmission. Having a reputable trans shop in my area rebuild it it for just under $2k.

This is ridiculous. We have a 2011 Sienna Ltd. AWD with about 39k miles and our transmission just went out. Was going up a steep driveway and just suddenly went out and the van just started rolling back.

My 2014 Sienna transmission went out at 85,000. Fortunately I had the extended warranty which covered it. This happened very suddenly also. This was my first Toyota because I heard they were so good and lasted forever without repairs. I don’t see this is a good sign. Also I hear a lot of road noise which has always been a problem from day one. Not happy about that either. Not sure I would buy another one. Well not to mention the fact that it did not come with a spare tire. Pretty hard to fix a flat tire out in the middle of nowhere without a spare tire

Replied on here 5 months ago with the second transmission going out on my 2012 Sienna AWD. Now the dealership diagnosed a engine rattle as a disintegrated bearing (unspecified) and engine needs replaced ($12,000). That makes a total of 2 transmissions and now a motor under 90,000 miles.

Hi I just bought a 2011 Toyota sienna awd le and it showes 2 faulty codes p0500 and p0746 one is speed sensor and one solenoid code any one with the same problem?

I also have a 2011 sienna. I bought it used with just under 90,000 miles. Within a few months the transmission failed. Replaced it and it failed again within a few weeks. Luckily the warranty covered that. Now, 3.5 years later the transmission failed again!!! I have always exclusively purchased Toyotas for their longevity...not anymore.

We had a 2014 Sienna Limited AWD with only 72K when the transmission went out suddenly on a road trip, very far from home. The WHOLE tranny needed to be replaced (because it is some "special" "closed" transmission) and the total cost was $7K! We also had to pay for lodging (very expensive as everything was nearly sold out & in mid-summer), and missed out on most of our trip plans due to being stranded for a week. The Toyota dealership shop we ended up at worked with them to have them pay some (they were the ONLY good thing about this whole situation), but we still were out $4K! The warranty had JUST passed! The tranny AFTER fixing continued to leak! We've had it fixed 3 times now (all within the 1 year warranty), and STILL leaking! Unbelievable! The 1 year warranty is about to expire, and it is still leaking, and the shop who fixed it can't be held accountable anymore. Toyota corporate should, but not having much faith in that. We get REGULAR maintenance, at both our local shop & Toyota dealerships, and were appalled! We've owned MANY Toyotas before this (4runner, corollas, Camrys, trucks, an older 03' FWD Sienna), with no issues. We even have a Corolla too, and NEVER had an issue. Not sure if this is a Sienna thing, an AWD Sienna thing, or just a "newer" Toyota thing. Writing corporate, as we are about to purchase another new vehicle, and not sure we will remain loyal Toyota customers as we've been for 20 years now. Anyone have thoughts or experience with other Toyota issues? Other Brand tranny issues?

It looks like the awd is a problem couse I now so many people with the sienna fwd no problem

2013 AWD with 110k, 3rd gear issue with clicking sound and now slipping. Never seen this on any of my other Toys, 5500-6500 replacement cost. Not cool Toyota.

Transmission rebuild is 4,700$ at mister transmission in Canada I had mine in for check and they told me it needs a rebuild after deleting code it is fine for me could this be a problem if you don't change the transmission fluid on time?I bought my sienna used so I don't know the history I got 215.000km on mine

@Jakob - I've gotten to over 206K out of my 2010 Toyota Sienna without a transmission issue until now--at least I expect that is what the issue is as it will not engage into drive or reverse (I can shift it and it registers as shifting - but nothing happens - it remains in neutral) We took a long trip about 6 weeks ago after a tune up - 1300 miles...and have driven it locally since then with no issues until today. We aren't going to get back home without getting it fixed...so no sure what to do at this point. It's been a great car up until now.

Sienna 2011 with 205k miles Just as climbing on a freeway won’t pass 3k rpms and lowers speed from 50 gradually to 30mph. Change ignition coils spark plugs 2nd tranny service. Still has a hard kick at 20mph. After that only fails when climbing the slightest angle climb. On the level areas shifts fine. It’s still no good to me just because I’m in a bubble of 20 miles with no problem.

I have similar issue with Sienna 2011. no warning and transmissino just failed. Dealer suggested to replace it with the manufactured one. very expensive. corporate office is not helpful at all. had 3 toyota in the past but NEVER goign to BUY again. they do not even discuss the issue.

We have a 2011 Sienna AWD that we purchased 6 months ago, at almost 155K miles. We switched from a Honda CR-V. We had a 3 oil change package with the local Honda dealer that we switched to the Sienna to finish it out. On the most recent oil change, the Honda service adviser mentioned there was a small leak on the driver's side of the transmission at the axle seal (Toyota part number 90311A0021); not leaking onto the ground but just around the transmission case. Later that day, we went to visit family about 65 miles away. On the way back, when we were almost home, the transmission slipped twice while accelerating around 35 mph. We made it home taking surface streets while accelerating gently. A couple days later, I called the closest Toyota dealer to see how much it would cost for them to install the axle seal. The young lady on the phone didn't seem to understand what part exactly I was referring to. I then found the part number listed above and gave it to her. She put me on hold to call the parts department, she came back quoting $1793.00 for the part and about $350 for the install. Seeing as the part's MSRP was listed as $17.93, I asked if perhaps there was a decimal error in her quote. She fumbled a little then asked me for my number so she could call me back when she sorted everything out. I obliged and less than 10 minutes later, she called saying she couldn't figure out exactly what part I needed replaced and just said it would be best to bring the van in so they can take a look. My first thought was "uh, yeah, so you can tell me I need to replace the transmission..." Not really in the budget right now... After doing some more research and thinking, we came to the conclusion that the tranmission must be low on automatic transmission fluid. Here is one video that I found very informative: https://youtu.be/cNcecuGzTDg The summary of this video is that these transmissions are very picky about their fluid level and checking/refilling the transmission with the proper amount of fluid is very complicated and requires very specific conditions and/or tools. Being in a bind for time, we decided to have one of the local Toyota dealers do a transmission drain and fill. I got three quotes between $176 and $329. I specifically asked for the transmission drain and fill instead of the transmission flush. The flush is generally more expensive because it requires the use of more fluid (obvious, I know). You may be thinking "why didn't you have the axle seal replaced?" Well, based on my research, these Sienna 6-speed transmissions seem to leak in general. What if that's just a given regardless of whether you replace the seals? I'm hopeful that in 3-6 months I can find a convenient time to put it on a lift and with the right conditions (ATF temperature), top off the fluid myself. All I need to get is a more advanced OBD2 scan tool that can read the ATF temperature. So, long story short, I had the Toyota dealer drain and fill the transmission today (almost 165K miles) and it seems to have resolved the problems we saw a few days ago. No slipping when accelerating aggressively and it seems to shift easier. It also seems more responsive to throttle input. I should also mention that the Toyota service adviser didn't mention anything about the leaking axle seal. You can make your own assumptions as to why not. TL;DR: Check your ATF level often (using the correct procedure) and make sure it is at the correct level.

2012 toyota sienna Driving from NYC to RI engine light show up and transmission started slipping I have changed ATF fluid still show it toyota longway Newport I told them I have diagnosed it it shows bad transmission solenoid they charged me for redignosing and showing me the same cod I told them price for new transmission 6000$ I told them take my sienna for 6k I have to find out how ro replace solenoids
