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.

Long time listener, first time caller. I have a 1982 Oldsmobile 98 Regency Brougham, that last summer I ripped the 307 out of. It now has a Chevy ZZ4 crate motor, backed by a TH 350 transmission. (Gasp! My hero!!! – SM) (Read More…)

Sajeev,

My winter car is a 2001 Focus, 170k, duelcam, with a stick. At about 155k the original clutch was replaced. A year and a half later the replacement clutch was replaced. Now the car is in my hands, roughly a year from the previous replacement, and the clutch is in dire need of being replaced. My local trusty mechanic does not do engine and tranny work because he doesn’t want business to back up with tear downs. That’s fine, but I asked his advice anyway. (Read More…)

As noted in a triumvirate of TTAC reviews, the Scion iQ is a fun little box that’s hobbled by a somewhat crappy CVT transmission – though, it should be noted, not to the “’Tis but a scratch” extent that the SMART is de-limbed by its godawful gearbox. The above text message was received from my wife after she drove one briefly.

Naturally, after telling her how disappointed I was in her total lack of ethics, I felt rather pleased. When I met Katie, she was a dedicated cyclist and transit-taker who hadn’t bothered to get her driver’s license until her early twenties. With a series of Acura mid-sizers rotating through Dad’s driveway, she regarded the car as either an appliance or a necessary evil.

And then, along come I with my idiotic fervour for the things. Sure, I gave up my first car for the engagement ring, but when we got married I bought a Ford Escort GT with a 5-speed and set out to teach my new wife how to drive it.

It wasn’t easy. There were frustrations and setbacks, tantrums and whining and sometimes I thought the tears would never stop coming.

She wasn’t that thrilled about it either. (Read More…)

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… (Read More…)

My 1999 Ford Ranger XLT is starting to come under some serious wear. I got it a while back and thought it was good enough, an upgrade considering my dog grew to be 70 lbs and didn’t fit into the back of my immaculate 1996 Acura Integra hatchback. I needed to upgrade in size so I did.

Now, this truck came with a few ridiculous caveats. With 140k on the clock, it’s starting to enter my personal danger zone for cars. Additionally, it had a big tow package on it, a 2 inch body lift and big 33” by 12.5” tires on it. Did I mention it has the smallest 3.0 V6? The previous owner did not regear the truck and therefore it’s a bit sluggish. Upon inspection of the truck after removing the bumpers, which were improperly re-installed after the body lift, it looks like whoever did the lift cut parts of the frame near the rear of the truck. It’s looking worse and worse.

Sajeev,

I always enjoy reading Piston Slap and want to ask about my truck, a 2007 Nissan Frontier with the VQ40DE (4.0L V6), 6-speed manual, and 42k miles. Sometimes the truck will rattle while accelerating at around 2200 RPMS. This only happens after completing a long freeway run (an hour or more) and occurs in every gear regardless of throttle position. The noise goes away after a few shifts or always after the truck has been shut off and restarted. It has been going on for 6 months or more (it took me that long to figure out how to duplicate it) and doesn’t seem to be getting any worse, plus it doesn’t trip any check engine lights. I can’t imagine how to replicate the noise for the dealership service department. Any ideas? Computer issue with the air/fuel mix maybe?

This is a quote from Nissan’s specs for the current Sentra SE-R Spec V: “6-speed close-ratio manual transmission with dual-mass flywheel.” Ok, so I am interested in buying one of these top dollar Sentras, but would like to know what a “dual mass” flywheel is. The Spec V is the only Sentra with it. Thanks!

I have a 2000 Kia Spectra GS manual with about 97k miles on it and lately it’s been doing something really weird. I’m pretty sure it has to do with the clutch. When I upshift the engagement is very rough, especially below 3k rpm. It kind of lunges forward and stops and forward again then finally picks up roughly around 3k rpm and the rest of rev range is smooth. On top of this there is also the matter of the tightening the belt for the power steering because it squeals at full-lock and fixing the brakes because I’m pretty sure the rotors are warped and need new pads and shoes.

So actually my question is whether I should actually fix these things since — and I’m going out on limb here — the repairs probably cost more than the car is worth. I’m in grad school and will be for the next year. As a result, I have very little money to go out and get another car, though my parents said they could help me out if I really need it. I’m not really attached to this car at all even though I learned how to drive with it. I just don’t see that many options for my tastes: I like manny tranny wagons and hatchbacks. Should I use my parents money while I still can?
