Update: We just got the Highlander back from second mechanic this week. He replaced the transfer case, we went thru the Y-Yard in Effingham, Il which is a salvage yard. They found one in Virginia that only had 40,000 miles ($795). Cost another $800 to have it put in. The second mechanic put in new seals before he installed it. First off I am not that familiar with Highlanders so someone that is may be able to add more. Not sure on different changes between years. So now to the cause. Apparently Highlanders from the 2005-2007 era had an issue with their transfer cases but not enough to warrant Toyota tell the owners(and this were someone more knowledgeable can help out) (and could be other years involved). Supposedly the vent system on those transfer cases are a poor design and get clogged easily, say for instance if you do alot of travel on gravel roads or live in the country. The first mechanic said he sees this a lot in trucks used in the coal mines. When the vent gets clogged the transfer case has no place to breathe when it gets hot. What happens is when enough pressure builds up in the case it will seek the weakest point which is the seal to escape. Apparently this is what happened, all the fluid leaked out and the transfer case of course was ruined. To check the fluid in the transfer case you have to get under the car and pull the plug. The transmission dipstick in the engine compartment only checks the transmission fluid in transmission it self. In our specific case I believe the first mechanic may have forgot to fill the transfer case because there was no evidence where the Highlander was parked each night that there was a leak. It lasted less than 6 months after we got it back from getting the seals replaced the first time. As far as the Highlander now, I have put about 100 miles on it since we got it back this past Tuesday and have had no issues or leaks. The second mechanic said he redesigned the vent someway to help it breathe easier. Hopefully this helps someone else.

My situation is not one of leaks. When the engine is started (cold), all is well. No clatter. As soon as you place the transmission in gear, there's a clatter coming from the lower engine (somewhere). The clatter goes away shortly after - seems when engine is slightly warmed. Anyone have ideas as to cause?
#305 of 315 2002 Toyota Highlander torque converter lockup
Mar 07, 2013 (3:30 pm)
I have been driving this vehicle since I bought it new in 2002. Just over the last month it seemed as though I was running higher rpm's at highway cruising speed than normal (e.g. 2000rpm at 60mph vs 2500rpm). It also did not feel the "shift" from 4th OD to lockup. Had it looked at 1 by a dealership and 1 by a Toyota field tech. They both say the "computer" doesn't detect any problems. I said "can't you just listen/feel what the problem is? maybe the fault codes are not working properly". They said "no, the computer says its going into lockup so it is" but it's not!. any help is greatly appreciated.

Really need help on a very basic question. Could I get some responses on what people are observing as the RPM at 60mph cruising. My vehicle is a 2002 Highlander, V6, AWD.

I have a Garmin SatNav with Ecoroute HD so can monitor speed and engine speed very precisely. I have a 2004 Kluger V6 AWD with well worn tyres.
At 2,000rpm, speed is 110km/hour (68mph) in locked overdrive. With overdrive off, it rises to about 3,000rpm.
That suggests that 60mph should be about 1,750 to 1,800rpm with overdrive on.

I have the same problem and people seem to think it has to do with the catalytic converter. IV been watching YouTube videos of people's cars that make the same rattleing noise as my 2005 toyota highlander all wheel V6 but there is never a clear answer.
#309 of 315 Possible transmission rattle
Sep 02, 2013 (6:21 am)
I have a 2003 4cyl FWD Toyota highlander automatic transmission. When I start there is no rattle but once I move off and come to to a stop about 200 yards away I have a rattle when slowing down, but once the car has come to a full stop it disappears unless i shift the gear lever from park to reverse, then i can replicate it, again very briefly. The rattle will be there for less then 5 minutes then may appear briefly at times but more so when engine is cold. I have check all heat shield and removed some and its not it. I also feel the rattle is possibly from the transmission and not the engine. I don't think it's the timing chain, I have replaced these on other cars and this noise is different, almost like tinny rattle or a lever trying to engage while a something is spinning? Would like to hear from anyone that may have had a similar experience, I have 180000 miles on mine. Cheers, Hyder

I have the same issue. I found an exhaust clamp loose on section from header to exhaust pipe.
#311 of 315 Highlander Transmission problem
Oct 07, 2013 (7:30 am)
I have an 01 Highlander with 165K on clock. Recently a condition began that has me puzzled. When starting cold the transmissions works fime. After about 3 or 4 miles if I come to a stop light or stop sign, when starting off again the transmission does not upshift into overdrive.This condition will continue on until I shut off the engine. At restart the transmission shifts normally again until I come to a complete stop, then again the failure to upshift into O/D. Fluid is clean and at proper levels.. Any clues??Thanks
