i have an 06 auto w/ 31k miles, and need to get the tranny fluid changed. i called several dealers in the area to see which has the lower price. I found two but one is telling me to get it flushed and one is telling me to drain/refill, flush is not good for the tranny. If drain/refill is just what i need then id rather do it myself.

 

why are you getting your tranny done anyway? not needed until 60k+ anyway so you got plenty of time to worry about it. the dealer just wants your money os they will do what you tell them to do. also know that if you do it yourself and your tranny messes up afterwards, you just voided your warranty.

 

High mileage cars have been know to have problems after a total flush so my mechanic recommends just a drain and fill. Lower mileage cars should have no problem with a flush. As Z04 stated, 31k miles cars don't need anything.

 

Flush it. Drain and refill won't get all your old fluid out, there's still quite a bit left in the TQ converter.

 

so a flush is basically waste of money

 

anything under 60k+ milage is a waste of money.

Reading Comprehension FTL.

 

doing any change to it now is a waste of money

 

are your comments based on your experiences, according to manual change tranny fluid @30k but doesnt say flush it. well i'll just drain /refill it

 

I believe that is with severe use for 30k.

 

ALL flushes are a COMPLETE waste of money. I have been in the automotive service industry my entire life and am currently a parts and service rep for a major automotive manufacturer. I feel really sorry for customers who pay for flushes of any kind. More often than not, they create problems and most of the manufacturers have written policy stating that a trans or engine failure will not be warrantied if it has every been subject to a flush, Nissan included. Just FYI.

BTW, dealers hate that manufacturers do not condone flushes. flushes are VERY profitable. the only thing flushed is your wallet.

 

This is why you buy a 6spd Tranny, Less expensive and easier to work with.

 

always has to be one that has no clue WTF they are babbling about. please do a search on all the problems (and replacements) for the 6MT then rethink your statement

 

i think you need to reread it. the service manual states that the transmission fluid should be checked/inspected at 15, 30, 45, 60k, not replaced. if you meet the criteria listed in the note (copied below) then you change it every 30K

 

I need more info on this. My car has 53k miles on it now and had it's first drain & fill 5k miles ago at a private shop. I had it done because the dealership told me that the fluid was dirty and needed a flush last time. The private shop recommended a drain only so I went with that. Well, I just got another oil change today at the dealer and they say it's dirty and needs a flush, which is $260. I'm at a loss on what to do. So should I get a flush? Or get another drain & fill or is the dealer just flat out lying to my face? How do you even check the auto fluid?

 

you don't check it. sounds like the dealer just wants money because my service guy never even suggests it with mine though it is a 2004 i bought Nov 2003 and just barely have over 42K miles on it. when they do fluid checks they always show me the fluid compared to the old (i am right there when they do this in the pre service bay)

 

Drain and fill is fine.. when you do a drain and fill, the fluid will be noticebly cleaner and more of a bright red. A flush is generally b/s to make extra money... we dont even have a flush machine for trannys @ our shop.

Its good to do fluids more often than not, preventive maintenance is cheaper than repairs... so I would definitely do it at 30k. I replace my tranny/diff fluid every 10k or so....and im not just saying this because im a nissan dealership tech

 

Most of the guys who claims they'll do a flush is probably just draining and refilling anyways. And then charging you an extra 100$.

Don't be one of those who takes there car into the dealer, gets quoted a 1000$ for maintenance and goes with it. With an auto I would definitely just do it around 60k.

When the blind lead the blind, it's seriously a problem. Here is the facts about flushing versus dropping the oil in the pan only. A flush done regularly will prolong the life of the transmission BECAUSE you remove majority of the friction material contaminates from building up and increasing the clutch band wear. Unfortunately, if you choose to wait till 60k miles.... the clutch bands wear excessively due to a "silt" like fluid. Because of this, the bands are now permanently worn and adapted to this silt like fluid. A complete flush will cause the clutch bands to not be able to grip effectively anymore because clean fluid is now too slick. If you choose to flush, you have to flush often to minimize this. For the common pan drain and fill, that works okay, but in the end the clutch bands will all be worn to ***** around 180k - 250k miles. Since engines usually break down at that time, the pan drain and refill works out the best.


If you disagree with me about the flush; get some 1000 grit sandpaper and sand down paint in soapy water. notice how the sanding gets gradually more abrasive if you don't keep applying the soapy water. if you constantly dip the sandpaper into the soapy water you notice that the sandpaper last much longer. the friction material on the clutch bands are the same except they will slip if they have been excessively worn due to prolonged unchanged transmission fluid.

Audi transmission are notorious for this kind of wear. With Audi YOU NEED TO FLUSH it every 20k miles or you will regret it.


If your 350z is already past 30k, it's technically too late to do a flush. If you did a flush and now your transmission slips badly. Put Lucas transmission fix into it. Their additives will resolve the slipping. Eventually the clutchbands sort of adjust again. I've saved a looooot of people headaches due to their irresponsible high mileage flushing with Lucas Transmission Fix.
