Hmmm...regarding replacing the transmission oil, I know that Toyota had oil sludge problems with the 3.0 V6 engine. To cure this problem, Toyota and Lexus offered an extended warranty on some of the older engines. However, to correct the problem with the 2003 and newer models, Toyota insisted that the oil be changed every 5,000 miles.
I wonder if Toyota has a similar problem with the transmission oil on HL? I've always had my HL served at a Toyota dealer, based upon the recommended maintenance schedules. Does anyone know when newer (than 2003) HL are supposed to have their transmission oil changed?

According to the manual for my 2001 F/awd RX300 there is no recommeded servicing of the transaxle for the life of the vehicle. When I discovered my ATF dirty and burned at only 40,000 miles the dealer advised me, and the factory verified, that the ATF needed to be changed every 15,000 miles.
I have heard that this was later revised to say that the ATF condition should be checked at every oil change and only drained and flushed if required.
The HL uses the same transaxle.

Sorry to hear that. Mine is a 02, 4wd, 3.0l and have suffered with tranny oil high temp since it was about 30K miles. Finally this month I found a car shop where the owner involved himself in my car ande recomended to chage oil, it was burnt, black, and replace it with Valvoline synthetic blend ATF.
As always now I have a VSC light on on the dashboard. Itīs suppose to be a calibration procedure what is missing.
Iīll let you all know when we perform it.

I have a 2002 V6 Highlander, 3.0L and for the last 6 months I have a strange problem with my SUV.
When decelerating from over 60Km\h to ~10Km\h, around 20Km\h I feel a shift shock. It seems to happen when it tries to downshift from 2nd gear to the first one. But this happens only when driving over 60Km\h and it's not all the time.
We checked the brakes, calipers, but it wasn't that.
Reading this thread someone was mentioning about a TSB mentioning a re-programing of the ECM.
Before taking my Highlander to the nearest dealer I test drove it again and came up with these conclusions:
- it happens only when I am over 60Km\h, in the 4th gear;
- it does not happen every single time I decelerate;
- if am in the 4th gear and I kill the over-drive before or when starting to slow down, so I manually force the transmission into the 3rd gear it won't give me this shift shock when reaching 20Km\h (when downshifting from 2nd to 1st gear);
- it does not happen if I put in Neutral any time before reaching 20Km\h.
Yesterday I took the car to Toyota dealer and I told them about the issue and that re-programing the ECM might fix the problem. They could not reproduce the noise and at the end they scanned the Engine Control Module and the Transmission Control Module.
They reprogrammed the ECM only and, weird, the service manager told me "it takes one week for the computer to relearn what it has to do". If I program a computer, I teach the computer what to do.
I did not understand his explanation. Can anyone confirm these words to me, please?
Since yesterday I had 4 milder shift shocks so I am not sure if reprogramming the ECM helped or not.
Any previous experience?

I have a 2005 Sienna with the same drivetrain. This engine/transmission combo does do the hesitation, but driving "style" can mitigate the problem a great deal. Try rolling on and off of the throttle instead of stabbing it to the level you want it to be at. A smooth application of throttle works better than quick changes. Also, if you know a hesitation is occuring, hold the throttle steady for a second and let the transmission's brain catch up. It's not perfect, but honestly, I have zero problems with the engine and transmission. I must be trained to drive in this manner and it's not an issue for me.

My HL is the same model as yours, it had the same simptoms but with some diferent causes. Mine was due to an overheating in the tranny. After taking it three times to the Toyota dealer I took it to an independent shop. We discovered that the ATF was blackened, with no viscosity.
I replaced the ATF with Valvoline semi sinth ATF and the over heating and all their simptoms dissapeared.
Now I have a VSC alarm and is what Iīm working on. As soon as I have the solution, I will share with you all.

I also have an 2002 HL. I have however a major problem now. Besides the black ATF, I now have grinding in the tranny. I am down completely.

Sorry to hear that, it seem as if you didnīt have an alarm on the dashboard and the tranny wrecked herself.
Why donīt you make a flushing on the oil and replaced that with a new and clean one.
Maybe is still posibble to have it running again?

sounds like the gears are not where they should be, 1st gear.

I have 170,000 kilometers, aka about 100,000 miles.
Had transmission fluid flushed, cleaner and additives at dealer. They heard noise and indicate its bearings noisy when in reverse. recommend replace propellor shaft. In Canadian dollars its estimates as approx. $2000 for parts and labor plus tax installed.
I only hear it in reverse once and while. Could keep driving until its a real issue.
not very mechanical savy. Looking for advice if I plan on keeping car till I run it into ground is it worth replacing now? What is impact of waiting till it wears more. Is it going to cause other damage.
