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.”

Piston Slap: Liberal Bleeding, Flushing Brake Fluid

Gregg writes:

Sajeev,

I have a 2006 Tacoma with 50K miles and anti-lock brakes. I feel it is time to change the brake fluid as a preventative maintenance measure. I have the tools and have bled numerous non-antilock brake systems and have done some research into what it would take to fully refresh the fluid. Some forum people suggest the usual bleeding procedure followed by causing the antilock feature to react by stopping quickly on a dirt road or similar circumstances and then re-bleeding the system. Also mentioned is using a code reader to actuate the antilock system.

Piston Slap: Sucking At Fluid Changes?

Longtime TTAC Commentator ajla writes:

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.

Piston Slap: Chronic Xterra Maintenance?

m koonce writes:

Sajeev – you wanted questions, I have questions! First – I love your column. Great advice, and well written. Now my question(s).

  1. I have a 2009 Nissan Xterra 4wd, X model, 52k miles, and no problems except door squeaks and rubber molding which wont stay attached but that’s trivial. My question is, when should I have a “tuneup” done – i.e., change the spark plugs. Should I wait until Nissan’s recommended mileage (105k miles I think), or do it sooner? And should I replace all the coils at the same time (I presume the truck has a coil-on-plug ignition setup)? What else should I have done at the same time?
  2. Re: same vehicle: at 36k miles (May 2013) I did a transmission fluid dump and refill at local dealership, and did the same again at 49k miles in May 2014, again at dealership. My plan is to continue this dump and refill procedure every year for as long as I own the truck. Am I on the right track here? I’ve also had all other fluids replaced, except brake fluid which will be replaced when I have a brake job done.

Thanks for your advice, and keep up the good work.

Piston Slap: Crystal Ballin' With Yo Tranny! (Part II)

Hey Sajeev,

Huge fan of TTAC and the piston slap articles. My problem is that I noticed my car(2007 honda civic)would shudder, under light throttle and low rpms especially when going up a slight slope. This usually happens at 30km/hr or 40km/hr. I took it to the honda dealer(4 months ago) and he said the torque converter(tc) needs to be replaced(300 for tc plus 900 for labour and stuff).

Vellum Venom Vignette: Of Portal Handling Pleasures

Hi Sajeev,

G’day from Down Under. Big fan of the Vellum Venom column of yours. Car design, and more importantly the smaller details of car design have always fascinated me, even though I couldn’t design a car if my life depended on it. The first bit of design that really hit me was the first appearance of BMW’s “Angel Eyes” on the E39 M5.

Anyway, I’ve always wondered when and more importantly why have the “pull-type” door handles become the norm?

Piston Slap: An Inappropriate Grab?
TTAC Commentator flipper35 writes:

Hi Sajeev,

We have a 2000 Dodge Durango 2WD with rear abs (hub assembly is different than if the front had abs if it matters) and 165k miles. It has been a pretty good truck with few issues but we do have an annoying one that came up. The truck isn’t a commuter for me, just for the occasional errand that my wife needs to run or when the whole family goes somewhere so it gets driven a couple times a week just a few miles on the highway into town and back. The issue is the brakes.

Ok, you asked for input and I’ve got a question about my 2003 Cadillac CTS. I figure I’m more likely to get a reliable answer from you and the best & brightest of TTAC than the goof balls at Car Talk (this letter is from February-SM), so I’ll ask.

Piston Slap: Dreading "The Dreaded" ATF Flush?

Jackson writes:

I own a 2001 Nissan Maxima and a 2006 Corvette, both purchased new w/cash. I know the Maxima with 105,000+ miles has had two ATF services, which included the “dreaded ATF Flush”. So far the thing keeps running, only issue (unrelated) was a Cat replacement (99,000) and 3 O2 sensors around the same time.

The 2006 Corvette at 5 years and 42,600 miles is due for a coolant service and I see that the ATF service is 50,000 (harsh) or 100,000 (normal). So far expenses have been limited to gas, once a year oil changes and a set of tires at 26,000 due to some aggressive driving, aggressive factory camber settings and a shard of metal. It’s been spotless so far besides a squeaky roof panel which has been solved by periodic application of Super Lube to some contact points. Should I do an ATF flush for the vette? It would be a BG machine. It’s a warm weather commuter for me (42 miles round trip per day of which 26 is highway miles on which avg. speed 75 mph which is just 3 days a week).

I have taken it on 6 long trips over the years as well as weekend cruises. I do use the paddles about 30% of the time, but do not really hoon it so much the past 2 years after getting 3 speeding tickets in 6 month period…which I fought and is another subject. So please advise.
