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).

Engine downsizing is all the rage. Making the engine smaller increases fuel efficiency, reduces emissions and cuts vehicle weight. With ever tightening fuel economy legislation in the United States and CO2 emissions regulation in the European Union, mainline manufacturers are turning to turbochargers like never before. In 2009 just 5% of cars sold in America sported turbos, and that 5% consisted largely of European brands like Volvo and BMW with a long history of forced induction. By 2013 that number had more than doubled to 13%. Honeywell expects the number to rise to 25% in the next four years and the EPA tells me that by 2025 they expect 90% of cars sold in America to sport a turbo engine. With turbos becoming so ordinary, what’s a turbo pioneer like Volvo do to keep a competitive edge? Add a supercharger of course.

Sajeev,

Thank you and the rest of the TTAC staff for providing the community with an entertaining and genuinely informative automotive website. I’m a long-time reader, and hope you can answer some questions I had about my wife’s 2009 G37 S 7AT. (Read More…)

Sajeev:

I was recently greeted with the warm, orange glow of a check engine light on my 2002 BMW 530iA with 93,000 miles. I took the car to AutoZone and had the code read. It’s a P0741, which indicates a failing torque converter. This is apparently a common issue on E39s with the ZF 5 speed automatic, as the seals in the torque converters tend to deteriorate.

Mr. Mehta,

My apologies if this has been covered, but I’m looking for advice on my soon-to-be out of warranty 2008 GMC Acadia. I’m at 64K and 4.8 years, so bumper to bumper is gone but power train is still good for a few months. (Read More…)

Hey Sajeev,

A few months back you helped me sort out a plan of action for my Ford Fiesta transmission problems, and I have another stick-shift quandary I thought you might have some insight on.

My second vehicle is a 2003 Ram 1500 (bare bones work-truck, standard cab, manual everything), which I’ve recently been doing a lot of maintenance on (new plugs, pads, rotors, u-joints, carrier bearing, and a few other things). One issue I haven’t been able to sort out is an odd grinding/squealing I get when the car is in gear at high rpms (3000+) with the clutch peddle fully depressed (on the floor), something akin to what you hear if you come off the clutch with the shifter only part-way into gear.

Sajeev,

In a couple recent Piston Slap articles you’ve mentioned that when driving car with a manual transmission its most efficient to accelerate with the engine near its torque peak, then cruise in the highest gear possible. This raised two questions in my mind: (Read More…)

For 2013, America’s cheapest car will get another bit of unloved technology to go along with its continuously variable transmission.

Not sure if this would be appropriate “piston slap” fodder or not, but here goes:
Our blossoming family recently expanded to five. My wife and I, and a three year old, a 20 month old and now a 2 month old fill up the house. We occasionally travel with our 75 lb dog. Knowing the Volvo Turbobrick would not handle the cargo/dog/people, and the PT Cruiser remains the most reliable vehicle ever built (even if the timing belt changes are a big pain) we decided to sell the Volvo for something more appropriate, if a lot slower and FWD.

Enter the Freestyle. We routinely get 28 mpg on trips, parts are cheap, we have lots of cubbies for kid’s junk and the car seats fit easily. I purchased a high mileage (150k) example that was a one owner (ish) with all receipts. It was a fleet car for some guy who then bought it when his company was done with it. It had the CVT replaced at 118k miles with a remanufactured transmission from Ford, installed at a dealer.
