Genesis G70 - MT Car of the Year

[MX793]

I believe my JGC has a fairly high stall speed.  It tends to use it as a cvt and unlocks the torque converter to handle more load before downshifting... Results in a smooth mushy throttle response

The Jetta is like that.  In fact, when accelerating from a stop, it doesn't lock the torque converter until you hit roughly 30 mph (which is just before it shifts into 4th).  The sensation is similar to an upshift, but if you watch the gear indicator in the dash, it doesn't change.  Then a split second later you'll sense another "shift" when it actually engages 4th gear.  I attribute the car's horrendous city fuel economy to the lack of lockup at city speeds.

Does it not lock up based on load, as in locking up 3rd for example and then unlocking/shifting to 4th and then locking?  I believe that is how my wife's/daughter's '09 Escape works.  It's a 6 speed and seems to lock up in lower gears in slower traffic.

G37 does the same thing, esp. with the most recent AT flash. Kinda annoying IMO.

I did not know old TCs didn't have lock up. Learn something every day

Lockup TCs didn't hit the scent until the 4sp ATs of the '80s. Prior, high stall converters were always a huge trade off.

It will lock up even later if I'm accelerating hard.  In "normal" acceleration (which is probably a tick slower than the average car around here accelerates to 30 or 40 mph), it locks at around 28 mph, just before shifting into 4th gear.  Seems like it will stay locked if I drop below 30 mph, but if I dip into the throttle very much at that speed, it immediately unlocks again.

But will it lock up in 3rd under mild acceleration?

Not that I've noticed.  When I'm driving the parking lot roads at the business park where I work (15 mph speed limit, I go no more than 20, have to slow down to 10ish for speed bumps), I don't think it ever locks.

I was puzzled by all the times that it seemed that the transmission was shifting on my wife's '09 Escape.  It seemed to have more than 6 speeds. I haven't done any research, but after 4th, it seemed that the converter would lock.  Maybe someone knows.

The locking/unlocking of a torque converter can feel like a gear change.  Were it not for the gear indicator in the dash on my Jetta, I'd swear it upshifts 6 times when accelerating up to highway speeds.

The way I understand it, it locks up based on the delta between the engine RPM and transmission input shaft being below a certain threshold.

I havent noticed the alfa ever unlocking the tc while driving... It definitely makes for more of a sporty and manual feel

No wonder manual got such better gas mileage. I don't recall the G being lazy with lockup though

Manuals usually had an extra gear too.

Good info. I've not kept up with reviews of this car and they're not sold in Europe as far as I am aware. Hyundai is definitely capable of building a sports sedan. Still interesting that they are offering a stick in this car in a class where manuals are dying out.
