Replying to: jayman6 (Nov 03, 2009 10:26 am) The conditions my Highlander had the vibration/shutter were in slow acceleration. I could reproduce very easily when going up hill or on an on ramp that had a slight elevation grade.

Replying to: vttaco (Nov 03, 2009 12:18 pm) sounds like the exact same problem and you reckon that changing the fluid fixed it? Did they use a different/special kind (did they reprogram the computer). Here's my conspiracy theory : the computers are programmed to leave the factory and change up to 5th real early at low revs, this helps them meet emissions regulations etc, then, after 1000 miles or so, they change their shift pattern to make it more driveable (at the expense of emissions) - far fetched?   how many miles have you done now?

Have had my Highlander a few months, It has continual transmission problems which Titus Will says it cannot find anything wrong. History: going slowly up steep little hill, car dead stops, gives a HUGE clunk, bang, I am slammed against seat, then it starts to go again. Diff day: cannot get out of park, only thing that worked was taking my foot off brake. Diff day: On hills, free wheels forward and backward (like your driving a clutch and don't know how). Transmission hestitates for a dangerous few seconds when trying to merge into freeway traffic, so instead of speeding up you are slowing down while transmission tries to shift. This hesitation occurs most of the time, especially when car is cold. Transmission problems are intermittant so I am thinking its a computer problem?? Not a mechanic, just a single pissed off mom with a bad car. Replies to this message: minnesnowta1 (Nov 04, 2009 11:28 am) alotawatts (Nov 26, 2009 3:02 am)

Replying to: parkerf1 (Nov 04, 2009 10:48 am) First, who is Titus????   Second, what kind of Highlander do you own. New or used?? 09/10 Sport/Limited AWD or base FWD? Engine, V6 or 4 cyl.   Third, does your Highlander have DHA (Down Hill Asst.) If you are using this on the road, don't. It's for off road, rough terrain use only.   It does sound like you have issues however. Replies to this message: alotawatts (Nov 26, 2009 3:02 am)

Replying to: stevied5 (Nov 03, 2009 7:17 pm) hi guys. i got exactly the same problem with my 2009 V6 4WD Sport which i bougt it last week. it now has 200miles on it and still does the vibration thing. also it has the following problem.   while drining in "D" position, if i let go of the gas, the transmission downshifs quickly. as a result, the car slows down very quickly as appossed to keeping rolloing that you would expect. if i switch to "S" position, the slow down would be much more natural.   My dealer says its a normal thing while the vehicle is breaking in. but i just wanted to make sure if anyone else have the same issue and if this is related to the 'vibration' problem also.

Replying to: kevincooks (Nov 06, 2009 8:52 am) my dealer said the same, and a number of others here have had the same problem, mine cleared up as did others, but I did notice it slightly once again last night but it occurred at 1100rpm which was very low engine speed but previously it occurred at 1500 rpm, I genuinely believer this is a running in issue or computer learning issue but I'm waiting a little longer to record a verdict I currently have about 850 miles on mine and the effect is a LOT less and harder to reproduce even when you are trying to provoke it. Because the car is so quite and smooth, you do notice it compared to something less refined. I also noticed that shifting into sport mode altered the change up points and the problem went away

Replying to: stevied5 (Nov 01, 2009 4:49 pm) I did the same thing stevied5! I was thinking the same thing (maybe I got a lemon../maybe this is why I got a great price on this..) and I did the same thing - trying to figure out if it's the road on every vibration or noise. Alas, it has calmed quite down and is such a pleasure to drive. Now I look at it with pure excitement as opposed to that same disdain feeling I had before. I love the HL now.   -mccartsj Replies to this message: wwest (Nov 08, 2009 4:04 pm) mccartsj (Nov 23, 2009 1:15 pm)

Replying to: mccartsj (Nov 07, 2009 7:52 pm) Until the battery fails, is disconnected, or replaced, and the engine/transaxle firmware reverts to the factory default parameters. Some engineer has picked a default parameter on the "wrong" side of conservative, too far in favor of FE apparently. Replies to this message: mccartsj (Nov 23, 2009 1:15 pm)

Replying to: wwest (Nov 08, 2009 4:04 pm) Well, I disconnected the battery at about 3,500 miles when I installed my Toyota tow hitch (you have to install a fuse and other electric components). It hasn't reared it's face after that, so I'm pretty sure that isn't an issue.

Replying to: minnesnowta1 (Nov 04, 2009 11:28 am) Titus Will is a dealer in the Seattle / Tacoma WA area It would help if people would specify year and engine !!!!!!!!!
