#2701 of 3687 1999 Sienna Transmission Failure
Nov 26, 2003 (11:15 am)
My 1999 Sienna Transmission failed after 99,000 miles. Fortunately, I had an extended warranty and I was covered except for the deductible. I replace it with a factory re built one. This had a three year, 36,000 mile warranty. I heard a loud whirling sound coming from the wheels. When the mechanic opened up the transmission, he found shavings inside. The pinion gear had begun to wear, and it was grinding the mating gear. I was glad we were not stuck out in the middle of no where. I wrote Toyota, and they said there had been no recall on this model. I have owned Toyota's for twenty years, and this a first for me.
I bought the car new. The car and transmission was perfectly maintained at the dealer ship the whole time. I even bought the extra cooler for the transmission, even though I never towed with the van.
After reading other comments, it looks like other owners have been experiencing the same thing. All I am asking of Toyota is have they found a generic problem, and are they going to fix it on future models?

The new brake drums really aren't going to do the trick. So after spending $400 in useless stuff, you now can spend about $15 on a fix. The magnets I put on mine work perfectly. I put mine on the backing plate or the round stationary plate that attaches to the axle...not on the drum itself. The problem is that there isn't enough mass on the backing plate and when you hit the brakes it causes the backing plate to hit that resonate frequency, therefore causing feedback in the form of a squeal. With the magnets, you're adding extra weight to the backing plate, changing it's resonate frequency. Try the magnet trick, you'll be surprised.

When I got my 3rd transmission, Dealer told me is a new model and ordered from Japan. My 2nd replacement was a re-built, only lasted a little over 1 year. Go back to your dealer and see if you can get a newly design replacement. Although I got no history of how well it will work.
#2704 of 3687 DVD volume very low
Nov 27, 2003 (6:28 am)
Picked up my 2004 Sienna XLE Limited w/DVD & Navigation yesterday. Overall, it is AWESOME! Only problem seems to be that the volume of the DVD through the sound system is very low. The volume is fine through the headphones. Has anyone ever heard of a problem like this?
I know that some systems require tuning the radio to a particular FM station in order to hear the DVD through the sound system, but with the integrated Navigation system, there is a separate mode for the DVD.
#2705 of 3687 New 2004 Sienna with Tire Thumping Noise
Nov 28, 2003 (12:07 pm)
I have just purchased a 2004 Sienna. On the second day of driving, a thumping noise and vibration have developed. This thumping is directly correlated with the speed of the vehicle. The dealer said it is probably because the steel belt on the front tire(s) (they are Dunlop SP4000 tires) have deformed from sitting too long in one position from storage. However, if this was the case, then why didn't I feel this thumping on the first day of driving? I didn't think the 2004 Sienna would have to be stored very long before being sold.
Has anyone experienced this problem?
Is the dealer correct?
Thanks in advance.
#2706 of 3687 Transmission reliability solution--synthetic oil?
Nov 29, 2003 (7:35 am)
I am in the market for a van since mine was totaled by a driver running a red light and am interested in the Sienna but the reports of a lack of transmission reliability concerns me. Some who have posted here recommend changing transmission fluid every 15k which seems excessive. It seems the problem is due to the van's, and others based on a car chassis, extra weight overstressing the transmission which has not been upgraded/redesigned to account for it. Would using synthetic transmission fluid such as Royal Purple/Red Line, or others, increase this reliability such that a replacement of fluid at 50k be performed with no ill effects?
#2707 of 3687 New 2004 Sienna whistling sound during decelaration
Nov 29, 2003 (2:46 pm)
When I take my foot off the gas (of my new 2004 Sienna LE),I hear whistling/humming noise & then the moment I put my foot back on the gas the sound stops. This is observed only at freeway speeds and is really annoying. Is anyone else experiencing this? Didn't approach the dealer yet. Thanks for your time.
#2708 of 3687 New 2004 Sienna radio gets on during a sharp U turn
Nov 29, 2003 (2:57 pm)
I noticed this once while taking a sharp U turn in my 2004 Sienna - the radio gets 'on' all by itself . I wasn't using any of the players (cassette/CD/radio) at that time. It was quiet & the moment I took this swift U turn the radio started to blast.
Anyone experienced this ? Not talked to the dealer yet.

Are you sure that in the flurry of hands around the wheel that you didn't hit one of the controls on the wheel center?

When we had our Avalon transmission repaired for the second time, I asked the service manager if he would recommend a synthetic ATF. He was pretty quick to say that a synthetic would void any warranty. Since we've run into Toyota being a stickler on the warranty thing in the past, I would ask your service manager and see what he says. I would get him to give it to you in writing, too.
