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: Reporting on The Oil Report

Greg writes:

Sajeev, first let me thank you for your interesting article on Mazda rust last year. Ultimately I bought the Accord, which to me seemed to have the superior (and quite lovely) stick shift, even though the Mazda is reputed superior in that department.

I decided for kicks and giggles to get my oil tested by Blackstone, and I thought this might be a potential article for Piston Slap (not my adventure, but the practice of having it done).

Piston Slap: Riddle Me This, Timing Chain Rattle

But wait…there is less???

As the Christmas Spirit draws near and Pistonheads relax with thoughts of good vehicular cheer…screw it, I’ll get to the point:

Can timing chain rattle on start-up magically resolve itself after a mere tune up?

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).

Hello Sajeev,

I have a question related to maintenance on a 2011 Kia Optima SX Turbo. It currently has 45k miles, and I have owned it for only 4 months (had 20k when I took ownership of it). As you can see, it is driven a whole lot, almost exclusively on the great interstates of the Southeastern US of A. I average 5-6k per month. I am an outside sales rep. and drive from SC to MS and everywhere in between weekly.

My question is this:

Piston Slap: Throwing (Ignition) Parts at a (Fuel) Problem?

Hey Sajeev,

Long time lurker here. Since you asked so nice, here’s a problem that I haven’t managed to troubleshoot myself, and so far my own searches & forum postings haven’t nailed an answer. My girlfriend drives a 99 Mazda Protégé. If driven for an extremely short distance (like from the street into the garage), it will not start the next morning. It turns over just fine, but doesn’t catch.

  • Bruce Purchased (in 2024) a 1989 Camero RS. I wasn't looking for one but I picked it up for 1500. I wanted to only pay 800 but the fellow I bought it from had a real nice family and I could tell they loved each other. They needed the money and I had to give it to him. I felt my heart grow like the Grinch. Yes it has the little 2.8. But the write up does not represent this car. It has never been messed with, all original, a real time machine. I was very fond of these 3rd gen Cameros. It was very oxidized but straight, interior was dirty but all there. I just retired and I parked in my shop and looked at it for 5 months. I couldn't decide how to approach it now That I can afford to make of it what ever I want. Resto mod? Engine swap? No reason to expect any finacial return. Finally I started just doing little things. Buffed and polished the paint. Tune up, Fluids. I am still working it and have found a lot of joy in just restoring what I have just the way I found it just fixed and cleaned up. It's just a cool looking cruiser, fun to drive, fun to figure out. It is what it is. I am keeping it and the author of this critical write up completely misses the point. Mabey the point is what I make it. Nothing more and nothing less.
  • George Now that the Spark And Pretty Soon Gone is the Mirage I really wonder how are you going to get A low rental price when getting a loaner car for the week or more? Cars that are big as spark usually cost 5 to 10 dollars a day for use in a week rental agreement.Where as a SUV like a Equinox or a Rogue Midsize SUV would cost about 20 to 30 dollars for the same length of time of lease and since you’re getting more space leasing is going to be very expensive.

  • FreedMike I do tip my cap to Musk for at least talking about pushing the edge technologically. But I'm betting no on this question, at least for the near-term future. This vehicle requires two technologies - no-driver-control autonomous driving and inductive charging - that aren't nearly mature enough right now, and they can't be willed into maturity by Musk.
