Anything is Possible... (photo courtesy: http://theinspirationroom.com)

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).

Hey Sajeev!

A question for you and B/B. Especially during cold weather my Trooper gets a ’clunk’ shifting from 1-2 (it’s a 4 speed automatic) and then back down. This coincides with a CEL. It doesn’t happen all the time. There are other times (even during cold) where the truck runs normally – no clunk, no CEL. Checking the CEL code and it indicates all four oxygen sensors (replaced last year); when no CEL no code to read.

My first thoughts were it might be time for ANOTHER transmission. But my brother says no, it has to be electrical since it’s intermittent. Any ideas where to start? (Read More…)

ZF 9HP Transmission, Picture Courtesy of Land RoverIn a week we will post our first full review of the all-new and all-controversial 2014 Jeep Cherokee. The new Jeep isn’t just raising eyebrows for the love-it or hate-it styling. Or the resurrection of the Cherokee badge. Or the constant delays in production. Or the transverse mounted engine. Or the lack of solid axles. None of that laundry list seems to cause as much discussion around the automotive water cooler than ZF’s 9HP 9-speed transmission. Click past the jump for a deep dive into the tranny with more speeds than my bicycle. If you don’t want to explore transmissions in detail, don’t click. You have been warned.

Sajeev,

I’ve got a small conundrum for Piston Slap.  Winter is fast approaching and for those of us in the mid-Atlantic states this is a serious affair. My winter beater has been my trusty (but not rusty) ’98 Saturn SL/auto/164K, which in the spring started showing its age and developed transmission issues after seven years (and roughly 80K) of ownership. I’ve let her sit most of the summer save starting her up and driving her around the parking lot every 7-12 days but I’ve been trying to put off the inevitable investment of Bennie bucks. This evening I was offered an ’00 Subaru Outback/auto/186K to replace it for $2500 inc four new cheap tires and inspection. (Read More…)

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…)

Hi Sajeev,

I enjoy your columns and thought I would get your input regarding what I should do with my current vehicle, a 2002 Acura TL 3.2. I purchased the vehicle new almost 12 years ago. The Acura has about 200,000 miles on it and is still on its third-transmission. As we all know, the transmission used on this vehicle was problematic but seems to be running okay. The car is very clean inside. (Read More…)

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.

Sajeev,

I have a quick but also possibly interesting question: in new VWs with DSG, the LCD info on the dash will tell you exactly what gear number you are in. Obviously with this particular transmission it’s necessary to do this. but why can’t other cars with conventional transmissions, either automatic or manual, have this small but useful feature? have other cars featured this?

Given the sudden multiplication of available gears in upcoming transmissions which have been a hot topic on TTAC recently, maybe it should be mandatory in a future sedan with an 8 speed transmission.

Also, FYI, my phone autocorrected your name to Sanjeev.

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…)

Hi Sajeev,

I have a transmission issue, but to mix it up a little, it’s not attached to a Honda.  This is my dad’s 1999 Dodge Dakota with the 3.9 liter V6 boat anchor.  When shifted into drive, it will move forward but will not shift itself out of first gear.  Moving the column shifter does nothing.  Reverse gear works fine. The level and condition of the trans fluid is good.  The truck isn’t worth much as it’s a 2WD regular cab (worthy of a scarlet A in New England), but here’s the thing: it only has 74,000 miles and is in otherwise good shape.  (Read More…)

TransmissionManOutIt wasn’t that many decades ago that imported cars— any imported cars— were considered fairly exotic. I’ve dredged up memories of some very funny 1980 Aamco ads that deal with that subject, and the internet has obliged by providing those very ads for us! (Read More…)

GM and Ford will be working together to bring 9 and 10 speed transmissions to market. Reuters reports that the two companies will jointly develop the gearboxes for both front and rear-drive applications, and expect to use them in cars, trucks and SUVs.

What do the Volvo XC60 and Lexus RX F-Sport have in common? Not much. Yet. Today’s vehicles aren’t just built on “modular” platforms, sharing parts with other vehicles from the same manufacturer, they are also “parts bin creations.” You’ll find the same power mirror switch in a Chevy, Jeep, Peugeot, Citroën, Lancia, Lincon and many more. That’s because car parts are like Lego pieces, made by a handful of car parts companies and designed to be everything for everyone. It’s cheaper for everyone to design one switch, one control module, one key fob and just alter some of the plastics and a connector to suit your new car design.

These days, with scrappers paying $240/ton (the going rate in Denver; I hear it’s similar elsewhere) for cars and steel car parts, we’ve seen an explosion in the numbers of guys cruising around in hooptied-out minivans, pickups and the occasional bicycle with trailer, looking for metal. The older parts of the Denver urban core, where I live, have alleys between streets, and so the scavengers (I call them Jawas) spend their days patrolling these alleys in search of stuff they can turn into cash at the scrapper. It turns out that these guys can smell a transmission as they pass by, even one that’s behind a gate and barely visible. (Read More…)
