I own a 03 Camry with 33k on it. I look all over my service manual, but I didn't find change trasmission at any milage or any time. I open the hood there is a sticker on the dipstick it says "No need to change transmission fluid." Last time I had 30k service the delaer recommand me to change the transmission fluid, is it a good advice?

Toyota's new fluid is supposed to last longer than 30000 mil unlike Dexron III. Although even when the transmissions ran Dexron III, it never gave a definitive schedule for changing the fluid under normal conditions.

I'm still changing my transmission oil at 30 000 miles though. I don't know how well GL-4 holds up...

most mechanics i talk to say flushing your tranny is a bad idea & can cause damage. on top of that i dont know any car makers that actually recommend it. If you change your trans fluid regularly i don't think its neccesary.

Gen 5's use Type T-IV transmission fluid. I've seen NUMEROUS cars with about 30,000 miles where the fluid was burned badly. The fluid should be inspected at regular service intervals and changed as soon as it's noticed that the fluid condition is deteriorated.

Gen 6's DO NOT have a "locked" transmission and should also be inspected and the fluid changed as needed.

Not all cars are the same, and not everyone drives under the same conditions.

Interesting. My gen 5.5 is at 26K miles now and the fluid is still bright pink and smells fine. I try to check it at the same time I pull my oil dipstick. I'll keep an eye on it and change it when the time comes.

many new toyotas have a locked tranny that you cannot change the fluid in.............but toyota can:rolleyes:
my 05 DC Tundra is one of the lucky ones. they said that it would need changing at 100,000 miles.
You can change the fluid, you just don't know how.

I don't know how to fly a helicopter, but I wouldn't tell people that they can't be flown just because I don't know how.

It's IMPOSSIBLE to damage a transmission by simply flushing it. The machine doesn't produce NEAR the pressure that the transmission itself produces. Most "mechanics" probably do believe that. However, I prefer the advice of a professional "technician" instead. Car makers don't recommend cleaning the throttle body, fuel injectors, alignments, etc. That doesn't mean that they shouldn't be done.

Flushing the fluid or simply doing a regular service (drain and fill), depends on the condition of the fluid. If it's in very poor condition, flushing is recommended the help exchange nearly all of the fluid.

I know alot of carmakers, toyota included, tell you to never change the trans fluid. I believe this is simply false, as the carmakers have their own agenda and we car owners have ours. we want our cars to last forever and they want to sell us as many new ones as we can buy.

Kind of mutually exclusive i think but thats just my opinion - but really no automaker has any serious concern with helping you make your car last longer than 100,000 miles anyway (and some cars are so bad - Ford for instance - you are very lucky to go that far without major repairs, no matter how well you maintain it).

I change the fluid on my 2002 V6 about every 30,000. I have done this on all the cars i have owned, and i have never had transmission work nor replaced a transmission.

I have a 04 camry V6 with 140k miles and a 92 Camry I4 with 260k miles on it. I do drain and fills every 15k miles and am still running the original trannies on both. A drain and fill only drains about 4 qts out at a time. The World Standard Toyotas have the black handles on their dipsticks or they don't have one at all. Some say that it is "Life Time fluid", but until Toyota warranties the trannies for life, I am going to stick with my schedule.

I added a transmission cooler to my '04 at 65k. At the same time I dropped the pan, cleaned the magnets, and replaced the strainer. Then I filled the pan, put the return line from the cooler circuit in a bucket, started the engine, and dumped in new fluid while the transmission pumped out the old fluid. A couple of passes through the selector lever and three gallons of fluid later, I was all done with my flush. It wasn't cheap, but it was a lot cheaper than the dealer, and I knew the work was actually done. The old fluid was black and definitely had been in there for too long.
