Piston Slap: A Fusion of Transmission Fluid Services?

Mike writes:

Hi Sajeev,

I bought my 2008 Ford Fusion V6 AWD about two years ago from a Ford dealer. At the time, it had about 65,000 miles. I’m now at 85,000 miles. I also bought the three-year extended warranty (one year left).

Despite my usual aversion to buying extended warranties, it’s proven to be a sound investment. I’ve had a few things (including an oil leak) fixed for free (minus deductible). The warranty has already paid for itself. The dealer I used for the warranty service (not the purchasing dealer) gave me a few free oil changes and some credit on an account, so I’ve been going there for routine oil changes/tire rotations.

At the last oil change/tire rotation, I noticed they didn’t check the transmission fluid. I asked them to do so. The technician checked the fluid: it was at the correct level, but getting dirty. I asked if I should change it and he mumbled, “If you don’t do it now, don’t ever do it. Transmissions get used to the fluid and replacing it might ruin the transmission.”

Hi Sajeev,

I do a more through job at the time of purchase, but every year after I do a drain/refill on the radiator and replace some transmission fluid by using my fluid extractor to vacuum up as much ATF as possible through the dipstick tube.

I know that I’m not getting all the fluids exchanged this way, but my question is how much of a positive impact is this regiment actually having on my cars? Am I just wasting my time? I haven’t suffered a mechanical failure since I started doing this, but I don’t know if that proves much.

Keep in mind that the vehicles I tend to own are 20 to 30 years old.

  • DenverMike When was it ever a mystery? The Fairmont maybe, but only the 4-door "Futura" trim, that was distinctively upscale. The Citation and Volare didn't have competing trims, nor was there a base stripper Maxima at the time, if ever, crank windows, vinyl seats, 2-doors, etc. So it wasn't a "massacre", not even in spirit, just different market segments. It could be that the Maxima was intended to compete with those, but everything coming from Japan at the time had to take it up a notch, if not two.Thanks to the Japanese "voluntary" trade restriction, everything had extra options, if not hard loaded. The restriction limited how many vehicles were shipped, not what they retailed at. So Japanese automakers naturally raised the "price" (or stakes) without raising MSRP. What the dealers charged (gouged) was a different story.Realistically, the Maxima was going up against entry luxury sedans (except Cimarron lol), especially Euro/German, same as the Cressida. It definitely worked in Japanese automaker's favor, not to mention inspiring Lexus, Acura and Infiniti.
  • Ronnie Schreiber Hydrocarbon based fuels have become unreliable? More expensive at the moment but I haven't seen any lines gathering around gas stations lately, have you? I'm old enough to remember actual gasoline shortages in 1973 and 1979 (of course, since then there have been many recoverable oil deposits discovered around the world plus the introduction of fracking). Consumers Power is still supplying me with natural gas. I recently went camping and had no problem buying propane.Texas had grid problems last winter because they replaced fossil fueled power plants with wind and solar, which didn't work in the cold weather. That's the definition of unreliable.I'm an "all of the above" guy when it comes to energy: fossil fuels, hydro, wind (where it makes sense), nuclear (including funding for fusion research), and possibly solar.Environmental activists, it seems to me, have no interest in energy diversity. Based on what's happened in Sri Lanka and the push against agriculture in Europe and Canada, I think it's safe to say that some folks want most of us to live like medieval peasants to save the planet for their own private jets.

  • MaintenanceCosts There's no mystery anymore about how the Japanese took over the prestige spot in the US mass market (especially on the west coast) when you realize that this thing was up against the likes of the Fairmont, Citation, and Volaré. A massacre.
