Myth or truth about ATF fluid changes?
Watching Scotty on this topic is he full of bull or does he have sense when it comes to ATF fluid change? My car is going to be needing that in 7,000 kilometer

You're also forgetting a group, lawyers.LeisureSuitL wrote: ↑ I would lean towards trusting the word of an experienced, (and honest) mechanic over than of an engineer.
Engineers do their due diligence to design how something is supposed to work, whereas a mechanic will see how things actually work.
Often the two paths diverge radically. This is why we have car reviews and mechanics that break down what cars were designed well and what cars were designed poorly.
PS. I also trust Scotty.

I'm living through this right now... Bought a used minivan with 120,000 km and found out afterwards that the previous owner did a transmission fluid flush (all fluids actually) right before selling it because he wanted the new owners to have a worry free vehicle. Guess what has started slipping that never slipped before?!? Had the van for 8 months and the hotter the transmission gets, the worse it slips but only from a dead stop. Fluid doesn't have enough 'grit' for the torque converter... Gonna try Lucas transmission fix and hope it solves the issue....sickcars wrote: ↑ +1 I agree with what hes saying here.
If you maintain it properly at the recommended intervals or slightly sooner it will last a long time. If you wait until you have 150k to change the fluid/filter then you will likely run into an issue.
My parents bought a used car a few years ago, it had over 100k on it. Well the transmission was never serviced so we took it to change the filter/oil and it actually started slipping a bit going from 1st to 2nd. We drove it for half a year or so but it was the same, we ended up doing the service again to see if that would help but actually made it slightly worse. Shortly after we traded it in but perfect example of what hes saying.

very common problem..to boot..unless you bought the vehicle new..you don't know the true mileage (very easy to roll back odo these days)...there is a line for tranny service and when crossed..you have to be very carefull...no flushes...careful and gradual drain and fill...maybe 2 litres at a time over months of use...you dont want to disturb built up varnish and clog all those little channels...doing it gradually will save headaches later.kr0zet wrote: ↑ I'm living through this right now...

As for Scotty, he's dead on this one.

This is not the first time I have heard this argument, but I'm not 100% convinced.engineered wrote: ↑ Lifetime fills really only mean for the lifetime of the warranty, because that's all the car makers care about. If you want your car to last, change all fluids regularly.

That is not only illegal, and fraudulent (if not reported). It's also very difficult to do for any modern car.

difficult my arse!...takes about 10 minutes and a laptop (and from $150-300)...especially on newer cars...angryaudifanatic wrote: ↑ That is not only illegal, and fraudulent (if not reported). It's also very difficult to do for any modern car.

ODO was not rolled back, it was a private sale from the original owner with all service records, and a co-worker. He took it into the dealership for an oil change and was talked into a transmission flush, engine flush, coolant flush all because he was selling the vehicle and it would 'add value' for the new owners peace of mind. He spent 1/4 of what I paid for it on his last service visit, which was suppose to be an oil change. It just sucks that the transmission flush may have been what is causing the problems now...cardguy wrote: ↑ very common problem..to boot..unless you bought the vehicle new..you don't know the true mileage (very easy to roll back odo these days)...there is a line for tranny service and when crossed..you have to be very carefull...no flushes...careful and gradual drain and fill...maybe 2 litres at a time over months of use...you dont want to disturb built up varnish and clog all those little channels...doing it gradually will save headaches later.

Fraud (misrepresentation) is a violation of the Criminal Code of Canada. If you sell a car, you are required to check a box that states something along the lines that the mileage was not altered.cardguy wrote: ↑ difficult my arse!...takes about 10 minutes and a laptop (and from $150-300)...especially on newer cars...
also...where is it in the criminal code...and why wouldn't the police charge a curbsider when both the former owner (whos name was still on the ownership) and myself (the buyer) had the curbsider dead to rights on a roll back
..cop said it was a civil matter..not criminal

when was the last case of this and how severe was the punishment...also does this apply to regular people selling "as is"?angryaudifanatic wrote: ↑ Fraudulent misrepresentation is a violation of the Criminal Code of Canada.

Extended warranties are also just money makers for the dealers. Statistically you will need less in repairs than the cost of the warranty over that period. A lot of those also require regular servicing, so more profit for dealer.angryaudifanatic wrote: ↑ This is not the first time I have heard this argument, but I'm not 100% convinced.
Why?
Well, automakers are now selling more factory endorsed, or factory recommended extended warranties. They have to live with the costs of their own decisions. Audi, as an example, allows one to buy an extended warranty to 10 years, 200k total. Mercedes, 7 years, 160K.
So I'm not 100% convinced that automakers only care about the 3 or 4 year new vehicle warranty here.

There's a reason class action lawsuits exist - the chance of an individual suing a carmaker successfully on his own is pretty much absolutely zero. Do you have the $50K your lawyer will want just to file such a suit? And if you did win all you would get is a free transmission and some jugs of tranny fluid to put into it. The carmaker just has to claim owner negligence was responsible for the transmission failure. They'll win every time - they'll have dozens of experts who will swear that the fluid wasn't responsible for the failure and they'll carefully explain how they determined some form of customer negligence was.angryaudifanatic wrote: ↑ Let's say that ZF states their transmission fluid is lifetime, and that the cause of a failure after 8 years ended up as being identified due to a lack of changing out the fluid - then, well, ZF is going to be on the hook after the carmaker gets sued by the customer.
