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

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:

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.

Until then non home owners are relying on public charge and one of my neighbors is in IT and he charges at work. It's call a perk.I don't see company owned delivery vehicles that are EV's. The USPS and the smiley boxes should be the 1st to do this. Nor are any of our mega car dealerships doing this and but of course advertising this fact.I think a great many of the EV haters haven't came to the self-actualization that no one really cares what you drive. I can respect and appreciate what you drive but if I was pushed to answer, no I really don't care what you drive. Before everyone goes into umbrage over my last sentence, I still like cars.

There are no breakthroughs in battery technology coming, the charging infrastructure is essentially nonexistent, and the price of entry is still way too high.As soon as an EV can meet the bar set by ICE in range, refueling times, and price it will take off.
