It requires a trannie flush machine..usually.

I used to rent cars from my local AAmco for business. I had a good relationship with the owner and he advised me NOT to power flush the tranny, just drop the pan and change the fluid. He said it loosens too much stuff and clogs the screen down the road.

DO NOT DO A FLUSH. Like the previous guys said, it clogs up the filter once you do it, and kills the transmission in worst cases.

Those high school dumbasses working in Uncle Eds and stuff like that just do what they are told. They tell you that it is recommended, but it is recommended if you want to risk getting a new transmission.

So what's the best way to go? Just change the filter and refill the fluid?

The only time you don't want to do a flush is if you have gone a long time before having a flush(70-90k miles or more) It is very important to flush your transmission as long as you have been doing it regularly, at least every 30k. I flush my trans fluid every 15k. It still shifts like new, doesn't shift hard at all. My trans fluid has never even been dirty. Toyota used to reccomend every 15k. Then changed it to every 30k. The main reason for transmission failure is due to lack of periodic fluid changes. The old transmission fluid heats up faster than newer fluid. If you are driving your car harder than normal or have forced induction I'd rec. installing a trans cooler and doing your flush every 15k.

my 98 i4 camry is @ 72k. no this would be the first tranny flush.

and by flush i was only going to change the fluid. not Power Purge wash it.

so should i go ahead and do it? or am i gonna fuck up the tranny?

How bad does the trans fluid look? Do you see any metal shavings in the fluid. make sure to drop it on white paper to get a good visual on the color. If it's very dark I would just do a drain and fill and change the filter. Then do the same thing every 30k. Do not flush it if it is very dark and has metal peices in it.

seeing as you know alot about tansmission fluids and such mine has had it done before my my parents. and i dont know when it was last done. i have driven it for the past 15k. now yesterday i went to a shop to do an expirement and they checked my trans fluid and it was dark not with metal pieces tho. so will it be ok to do a flush?

thanks

Check the shops records that your parents brought the car to usually. They should have the records in their computer system. I'm guessing if your parents did it every 30k then worst case scenairio you went 45k on the fluid. You should be ok to flush it. Especially if you don't see any metal pieces in it. It would also be a good idea to have the pan gasket and the filter changed this time around.

OK... You guys are really into your myths! There is nothing wrong with flushing a transmission. If you flush a dieing transmission, it will die. If you don't flush a dieing transmission it will still die. The point is that you've waited too late and the transmissino is about to fail either way. Also, niether means of flushing a transmission "power flushing" forces fluid through your transmission at some super rate to clean it. Pump inlet flushing machines use the transmissions own pump to flush the fluid while cooler line fleshing takes the fluid comming from the torque converter.
Pump inlet flushing is better.

You can only change about 1/4-1/3 of the transmission fluid in toyota AT's by draining the pan. It normally takes 12-15 quarts to fill a Toyota AT.

trdcamry2003 is right on. If the fluid has metal flakes in it, the transmission is dead, it's only a matter of time b/c you've already ground it up. Otherwise, change it every 30,000m.

I bought my Camry with 70K on the clock and changed it when it hit 155K on the clock. I didn't have any problems and the fluid still looked pretty damn good. Changed to a Purolator tranny filter and I think it will last; not saying that I'm going to wait that long for the next change.

But at least I change the oil every 3000 miles.

wow, whens the last time you filled a dry transmission?

7-8 quarts max in mine, including the torque converter.

who told you 12-15 quarts? expecially in a camry. you realize that almost 4 GALLONS of fluid you're talking about here. we're talking about a tranny, not a radiator.

[Rasco]

I've never done a tranny flush with the machine before. But I do change the fluid and filter once in a while. The transmission is still running good tho' on m 92 camry.

I heard if you have any leaks the power flush would make it worse because of the pressure increase. And that all the crud coming out might clog the transmission filter.

I was thinking.....I really want to clean/flush my transmission because Im also rebuilding my motor at the same time.

I wanna get that power flush. Then once I get it back I plan to drop the pan and change the filter myself and and then add a B&M cooler.

What do you guys think? Is this ok? Or will it cause other problems besides the filter being clogged?

Also....are there other transmission fluids you guys recommend for high mileage cars?

Thanks
