Piston Slap: Garbage In, Garbage Out!

Stefan writes:

Dear Sajeev,

I am the last person who would want to be even peripherally involved in you losing your job or impeding that great Lincoln rebuild. I am a loyal reader of TTAC and “slavishly” read your column.

My Subie is just touching 120,000 miles. It has been a really great, reliable ride and I fortunately have a good dealer and private mechanic for the routine issues that pop up.

I want to keep the car as long as possible. I do oil changes and the roughly 60,000 mile recommended scheduled service on time. The engine sounds good, has good (for a Subie) pick-up, averages 20 to 23 miles per gallon, and still has a tight body. I anticipate the need for new shocks at some point soon and a muffler/cat replacement.

Piston Slap: Are You Jagsperienced?

Sajeev,

Hopefully you can offer some light at the end of the tunnel for an issue that a friend has with her 2004 Jag X-type. The car is in great shape for its age and all was well until the bad news came regarding the transfer case. The car recently started acting up and the local Jag dealer diagnosed a failed transfer case with a part price of 3,600 with 6+ hours of labor.

I’m not Jagsperienced so I have to take their quote at face value.

Piston Slap: Justy-fied Freestylin' Over CVTs, Part IV

Mark writes:

Hello,

I enjoy reading the piston slap series.

I have a 2009 Altima with the 2.5 4 banger and the CVT transmission. I’m not a big fan of the CVT, but it works ok and gets decent mileage. I bought this car as it was the cheapest car I could find that fits 4 adults and qualified me for the cash-for-clunkers handout. I didn’t expect to keep it long or pile the miles on it this quickly but now it has 90k on it. I mostly drive it without any passengers as we now have 3 kids and the minivan gets used for family duty (just had one kid when we bought the Altima). I’m trying to decide if I should hold onto it or sell it – it’s kind of at that point where if I keep much longer, I’ll probably end up driving it into the ground.

Piston Slap: Divorced Sleeper Flew The Coupe?

Hello, Sajeev!

I need your wisdom and sound advice, Kind Sir. After what could be called a much needed separation from my wife (undoubtedly the beginning of a very long divorce proceeding), I purchased myself a vehicle. A 2006 Accord Coupe v6 6-Speed.

Piston Slap: Byzantine Transmissions in Frozen Highlands

Mehran writes:

Greetings to you Sajeev and your evil twin Sanjeev, (yeah he’s dead to me – SM)

First of all thank you very much for answering my other question, just to give you an update on that, I ended up not buying the extended warranty. Now we recently bought a 2012 Toyota Highlander Limited to replace my wife’s old car(V6, 5 Speed automatic with the towing package which adds the trans cooler) it has 34K miles and this one has the extended warranty (100K or 2019). The issue that we have with the car is as follow, after a cold start (in the morning) if I put it in any gear (D or R) something funny happens, the transmission acts funny, it goes in and out of the gear couple of times. For example if I want to back-out of the garage when I put in R and give it a little gas it starts going but for a quick second it seems like that the transmission dis-engages and then re-engages and the tachometer jumps from 1K to 3K. If I wait about 10 sec after I start the car and then put in gear everything is OK.

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

Aaron writes:

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).

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.

Piston Slap: An STI With A "C. Diff"???

Hello Sajeev+Piston Slap Audience,

A few weeks ago I saw something strange with my lightly-used-never-abused 2005 Subaru WRX STi — A “R. Diff Temp” started flickering on the dashboard.

Piston Slap: Demand Satisfaction…via YouTube?

TTAC commentator hidrotule2001 writes,

Sajeev,

I’ve got an intermittent, befuddling problem with the manual transmission in my 2011 Ford Fiesta: The shifter will periodically refuse to move into 4th gear.

This usually happens 10-15 minutes after the car is started, and mostly during warm weather (but I’ve never been able to consistently reproduce the behavior). When i say it refuses to move into 4th gear, I mean with the clutch fully engaged (peddle to the floor) attempting to move the shifter into 4th position feels like trying to shift into 1st gear when going 60 miles an hour; like there is some sort of synchro problem.

Moving the shifter back to the neutral position and trying again doesn’t change the behavior (the shifter never gets far out of the neutral position to begin with). Down-shifting to 3rd, and then trying to shift again does get rid of the problem (at least so far), which is why I haven’t been able to demonstrate it to the dealer.

The car is 100% stock, and only has 10.5k miles on it. I’ve done some searching on various forums and the closest I’ve found is a couple of posts on Mustang forums with similar issues where the transmission fluid was low, but I’ve had that checked and everything is within spec.

Any ideas on what might be causing this? The problem is an annoyance right now, but I wonder if it might indicate an underlying issue that could get worse as time goes on…

Piston Slap: Honda Slushbox Fail...Averted!
Jonathon writes:

I’ve been remiss about getting results back to readers. I took the car to the Honda dealer who pushed hard for the power flush . . . only to have the technician do the 3X manual flush. Turns out that only some 2003 V6 Accords have the available connections to handle power flushing.

Results? The transmission has been Smoooooooooth ever since — how could it NOT be when the old fluid looked and smelled like old, overcooked coffee? Because the final draining still smelled a little off, I’ll probably do yet another tranny drain with the next oil change.

Thanks for the advice.

I've read that the new CHIPS act which is supposed to bring semiconductor manufacturing back to the U.S. is so loaded with DEI requirements that companies would rather not even bother trying to set up shop here. Cheaper to keep buying from TSMC.
