THANK YOU I'm not crazy. (Well....)

Like I said, this issue is 'picking nits'. The automatic is good otherwise. Like the quick shifts and how it senses when you are feeling 'frisky', by letting the engine rev.

Despite that, I'm glad my other two cars are manuals!

Also holds a gear through a corner, and if I'm braking on a descent, it downshifts for some engine braking.

Re-read the sequence of events (and recognize that you assumed a couple data -- which, for the record, happen to be incorrect), and you'll realize your implied accusations are unfounded and unproductive.

Should an identical situation occur, let your punk in. I won't. But I'll take less pleasure in triggering my 5-litre exhaust at him, and more in my action toward the reformation of a driver who evidently thought himself superior enough to butt in.

Yours is the MT, no?

By the way, what kind of 0 - 60 time are you getting now in your extraordinary hot rod?

Now I'm wondering about mine. I did read that the R does not have a launch control mode. (Makes sense, considering all that torque.) But now I'm wondering about how to achieve the quickest 0 to 60 in an OEM R AWD.

Anyone?

I measured multiple 3.8s via OBD2 port sensor using S mode, no shifting. Best I could do manual so far shift from 1st was 4.0s (only had one time out with sensor so not a bunch of data yet).

Numbers may not be exactly accurate for all the metrologists that seem to roam these forums but I feel like at least there is solid relativity between the two given I used the same sensor for both.

Love the ZF auto

Never use the stick shift, mainly let it change gear itself, upchanges and downchanges are influenced by many parameters such as throttle position, recent driving style, braking, braking downhill (will select lower gear automatically for increased engine braking)
Cornering , will hold gear.

If I want extra control then I use paddles, I understand the point made by members that the fixed paddle position makes gear changes difficult when significant steering lock is applied but was taught that it's not good practice to he changing gear mid corner so if in manual mode will select appropriate gear before entry to corner then hold gear through corner whilst accelerating, no need to change until corner exit when steering wheel position is in correct place for easy paddle access.

Agree car never starts in first gear unless specifically selected. On my RWD R model first gear starts require very judicious throttle application even on dry roads and P4SS tyres to avoid loss of traction with wheelspin.

Yes. Not many places around here to get an accurate reading. For best results all the nannies need to be turned off and the back end gets too squirrelly to stay in lane, so I rarely apply full throttle in first gear or the bottom of second. One of these days I’ll get it on a drag strip.

I'm sure I'm not the only one on this forum who would love to hear your 0 to 60 time.

I have two situations in my daily drive that require a shift while turning if I'm in a hurry. I just let the rear end wander about and drive through it - but I only have 340 hp... It can also occur when doing 90 degree turns - at least the way I drive.

An auto trans indeed often is only as good as its tune, just like a set of bad tires can kill an otherwise good car!

A lot of it is deficient OEM tires. I swapped to Michelin Pilot Super Sport and later to Michelin Pilot 4S and now traction is only lost only when I do something stupid. Downshifting alone doesn't do it (maybe if I money-shift, but I am not going to try it).

The thing I find with this trans is that starting out slow from a stop the trans doesn't seem to know what to do, car seems to lug some like it can't find the correct gear. Maybe it's operator error, who knows?

The torque converter can be slow to grab. I find dynamic mode helps that, with a bit more aggressive throttle mapping.

That's the second gear start that I was trying to eliminate/work around.

Granted, an upshift from 1st to 2nd needs to come quickly. But at least the F wouldn't be the last one off the line at a traffic light!

Dynamic Sport starts my '14s in first. I have this same tranny in our '17 Ghibli S, starts in first in sport or manual mode. It's tuned different than the Jag but is just as effective.
