Automatic Transmission
After years of dealing with this issue toyota has yet to provide a reason or solution. When traveling at lower speeds the transmission disengages and when you need to accelerate there is a 1 to 2 second delay before the transmission re-engages. Toyota made me service the transmission...no help....then they claimed i needed a software update...which they charged me $80 ...to update their software design flaw.…

He was the only person in the van at the time, the van was not running, there were no keys in the ignition.. Yet somehow, the van's transmission was taken out of park and put into gear. As the parking brake was not set, the van rolled backwards down the driveway, through a fence and into a ravine with the child…

While merging onto a hwy i was leaned forward looking through the side rear view mirror with my right hand beside the seat hanging down. I raised my hand to place it on the steering wheel and my fingers caught on the shifter. The gear shift slid without resistance into reverse and the transmission shifted to reverse and started trying to go backwards. The transmission is completely wrecked and needs to be replaced.…

I have a 2004 toyota sienna, with only 70,000 miles. I suddenly and intermittently lost power steering. It was not total loss--that i could have handled, but it would come and go, even within a single turn. When i turned the wheel, i could not predict how the car would respond. No accident, fortunately, but a couple of close calls. I drove immediately to a t dealer, and they diagnosed a failed u joint and replaced…

I always took my 2004 toyota sienna in for maintenance. The maintenance was performed by midas or toyota. I took the vehicle in for brakes august 2008 and was told a timing belt was needed along with driving belt. I was never verbally told of a problem with the transmission. I took the vehicle back in for service to replace the timing belt, driving belt, and thermostat; still no mention of a problem with the…

I've seen other complaints about the transmission being hesitant and the car surging and slowing unexpectedly. I've had these problems, too. The dealership told me i needed a flash to the computer that would give the car a shift enhancement. They said it wasn't part of the powertrain warranty, but then agreed to do it for the $45 i initially paid them to look the car over. It shifts more aggressively now, but it…

Vehicle hesitates when accelerator is pressed. Vehicle 'surges' at times when brake is depressed. Similar to other complaints noted in this section, my sienna has a rough transmission, tires occasionally spin out with normal acceleration from a parking lot, toll booth, etc. Repeated trips to dealership bring no satisfaction: response from dealer is that vehicle is operating within standards. *nm

The transmission has a delay when running at low speeds and when having to change gears up or down under a change of load condition; like going uphill or passing. Very noticeable when you take your foot off of the gas for a moment, like turning into a street or driveway. The van will jump into a gear like if someone had popped the clutch on a manual transmission. I have had this problem since i have owned the van. I…

I have a 2004 toyota sienna with a transmission hesitation problem. (a problem toytoa denies but there are thousands of complaints about it to dealers) it is dangerous in snowy conditions as the 2 second hesitation results in a slowing down before an abrupt upshift/power surge that breaks the wheels loose in the snow. This then causes the traction control system to engage. I was stuck repeatedly and in many…

2004 toyota sienna xle van. When accelerating from a coast the van hesitates. Have to press the accelerator harder to force a hard downshift. This is very dangerous when a predictable acceleration is needed. It seems like the transmission control gets confused on when to downshift. Probably a result of what toyota has to do to keep the mileage rating up. The number of times this happens are to numerous to count. *nm
