Car Forum / Toyota / Toyota Cars / October 2007Do you need to flush?
Interesting: http://autotechrepair.suite101.com/article.cfm/040206 My Toyota dealer charges $169.45 + tax for transmission serice. I quote "Using state-of-the-art machine, one of our technicians ill clean and flush harmful deposits from your car's transmission. Thos servie cleans the transmission filter, screens, valve body and torque converter while removing the contaminated fluid and replacing it with new transmission fluid." Its funny they don't have anything on their brochure about simple drain and fill of ATF every 2 years. > Interesting: > > http://autotechrepair.suite101.com/article.cfm/040206 > My Toyota dealer charges $169.45 + tax for transmission serice. > I quote "Using state-of-the-art machine, one of our technicians ill > clean and flush harmful deposits from your car's transmission.

Gee, the better learn to spell better. Words like will, this, sevie are not that hard to spell and can be caught with a spell checker. If the dealer can't even put up posters without misspellings, why would anyone trust them to work on their cars?

The difference in this method and the simple drain-and-refill method is that they connect the machine to the tubes that send transmission fluid through the radiator, then they pump fresh fluid through backwards. This takes the crap out of the screen and pushes it into the recovery sump on the machine, and replaces the fluid through out the transmission with fresh fluid. Simply draining and refilling leaves passages and the screen filled with old fluid and debris. > My Toyota dealer charges $169.45 + tax for transmission serice. > I quote "Using state-of-the-art machine, one of our technicians ill [quoted text clipped - 9 lines] >> >> http://autotechrepair.suite101.com/article.cfm/040206 > I had my transmission flushed that way for $70. > [quoted text clipped - 5 lines] > fresh fluid.

Is this an example of fixing something that isn't broke? Jeff >> The difference in this method and the simple drain-and-refill method is >> that they connect the machine to the tubes that send transmission fluid [quoted text clipped - 8 lines] > > Jeff I don't think so. The fluid normally makes its way through the transmission and collects crap. The screen traps that crap as soon as the fluid re-enters the transmission from the radiator. If the flushing machine was connected to pump fluid backwards through the transmission, then the crap on the screen should be dumped into the sump on the machine without contaminating any of the rest of the transmission. >>> The difference in this method and the simple drain-and-refill method >>> is that they connect the machine to the tubes that send transmission [quoted text clipped - 10 lines] > > I don't think so. I think the keyword is "think." The bottom line is that neither of us knows for sure. What I do know is this: 1) If you flush your transmission regularly, it will last a long time. 2) Dislodging dirt is not a good idea, because it may not be properly removed from the engine. 3) No one has shown a net benefit to the people buying the service. However, there clearly is a net benefit for the people selling the service. > The fluid normally makes its way through the transmission and collects > crap.

Yet we don't know that what "should" happen does. So I think this is a waste of money. Jeff >>>> The difference in this method and the simple drain-and-refill method is >>>> that they connect the machine to the tubes that send transmission fluid [quoted text clipped - 31 lines] > > Yet we don't know that what "should" happen does. Well, assuming that people that do the job have any sort of pride in a job-well-done, they will connect the hoses properly so that the intended result actually happens. Having said that, I paid $70 for the service on my car, and I did not have to crawl under it and take the entire transmission pan off. Even if they did not do what they said, the worst that would happen is that the new fluid would be pumped through the screen that already had caught the loose crap floating around inside the transmission. The sh.t on the screen was not pumped backwards into the rest of the transmission. Waste of money depends on how much money is involved. Since I found a place to get the job done for $69, $169 plus tax at the dealership is a waste of money.

A lot of them around here are charging around $135 for the flush, and round $100 just for the oil change. I'm also confused though, because some people are telling me that my car uses a transmission oil filter, similar to the oil filters they use for the oil, and that needs changing too. Then other people tell me it's just a screen. Wish I knew which it was. ( 93 DX Wagon - 1.8 liter EFI ) >"Jeff Strickland" <crwlr@verizon.net> wrote : > [quoted text clipped - 65 lines] > >( 93 DX Wagon - 1.8 liter EFI ) It is a screen. You could do it yourself and save a bunch. Get a siphon and suck what you can out the dip stick and replace it with Toyota fluid each time the oil is changed. After about 4 or 5 times of doing this you will have essentially new fluid. I can get about 2 3/4 quarts out this way.

Yes. I found one at an auto parts store. It has a rubber bulb in the middle with a one way valve. I think it may be designed for gasoline, but it works great for transmission fluid.

Why, haven't you suck stuff in your mouth before?.. just kidding. I posted this question way back but many said just drain from underneath the car, I dont know why now its back to suck the oil from the dipstick? >> Are there siphons that can hook up to the dipstick tube directly? Ones >> with a hand pump, where you don't have to suck the stuff in your mouth [quoted text clipped - 4 lines] >the car, I dont know why now its back to suck the oil from the >dipstick? Cause it is easier to 'suck' or more to the point, siphon it out the dipstick for some of us. Others like to lie on their backs and take the drain plug out of the transmission and pour the transmission oil all over our hands. Works fine either way. I prefer not to get the oil all over me.

But, that's why its called a drain plug right? and a dipstick is just to dip the stick.

Some like it on their backs, some like doing it orally. It was always thus. >> Are there siphons that can hook up to the dipstick tube directly?

Here are a few that look like they will do the job.... http://plumbing.hardwarestore.com/52-302-siphon-pump.aspx I personally use one that looks like the cheap one at the bottom. SignatureScott in Florida > >> Are there siphons that can hook up to the dipstick tube directly?

I may try this instead of using the drain plug. I'm just curious how deep inside the dip stick do you get the tubes, is it longer than the dip stick or about the same length? >> >> Are there siphons that can hook up to the dipstick tube directly? Ones >> >> with a hand pump, where you don't have to suck the stuff in your mouth [quoted text clipped - 18 lines] >inside the dip stick do you get the tubes, is it longer than the dip >stick or about the same length? I just run the tube in till it bottoms out. Longer than the dip stick, but not much. Of course you have to back it back out an RCH so the fluid will flow... The tube is aprox 11/32" outside diameter.

Are they small enough to get sucked out from that diameter? Is the dipstick before or after the filter screen? >> >> >> Are there siphons that can hook up to the dipstick tube directly?

Is the dipstick before or >after the filter screen? If you do it every 10K miles or so, you won't see any dirt. Keeping the fluid fresh is probably the best thing you can do for your transmission. One caveat....make SURE you use the proper fluid for your vehicle. SignatureScott in Florida <snipped> >> >What's the diameter of the tube you use to suck the ATF out?

Is the dipstick before or > after the filter screen? The dipstick/filler tube drains into the transmission oil pan. The screen is above the oil pan on the valve body.

Toyota does not recommend engine or transmission flushes in their maintenance schedules. IMO, engine flushes are a waste of money. The only time I might consider one is if my engine were sludged from lack of maintenance and I was willing to gamble the cost of an engine flush as a last-ditch effort to try to avoid replacing the engine, and knowing that the flush could also finish the engine off. Transmission flushes might be more helpful if they were performed at the automaker's recommended interval for transmission fluid change, but if the vehicle is past the recommended interval, then transmission flushes are more likely to do more damage than good. That said, Toyota's recommendation is for a simple drain and refill, which is what I do for my personal vehicles. I have never had a transmission problem in any of my vehicles. SignatureRay O (correct punctuation to reply) > Toyota does not recommend engine or transmission flushes in their > maintenance schedules. > > Ray O > (correct punctuation to reply) But the dealers always recommend them (well most of them). Doesn't Toyota have some sort of control over the dealers so they don't do unnecessary services? >> Toyota does not recommend engine or transmission flushes in their >> maintenance schedules. [quoted text clipped - 5 lines] > Toyota have some sort of control over the dealers so they don't do > unnecessary services? No, dealers are independent businessmen and set their own prices and sales and service practices. SignatureRay O (correct punctuation to reply) If its yellow, let it mellow, if it brown, flush it down. > If its yellow, let it mellow, > if it brown, flush it down. too bad I'm color blind =) |
