I had an automatic (sportshift) Acura and it frequently frustrated me. For example, I'd be in 4th gear and downshifting to 3rd would NOT have overreved the engine but the computer said "No" to my downshift order frequently. And sometimes I'd tell it to upshift and it would take a couple of clicks of the lever to make it happen. Little stuff like that got real annoying. It seemed like it was frequently in the wrong gear compared to what I would have done.(I know the IS tranny is different in that the driver is just telling it the highest gear to use and letting it choose from there.)
To make it worse, my 4th gear was way too tall and gutless for a 5 speed tranny. Someone accurately described it as a 6 speed tranny w/o the 4th gear. There was that much of a ratio gap between 3rd and 4th. Has anyone noticed any gearing defficiencies like that with the 350?

drove it for 5 years, been in the IS for a couple of months
the IS350 sport shift is not going to solve any of your problems
mike, the IS tranny is better all around in all of those areas but you're still going to have issues if you are looking for this to be like a manual shift.

Yeah I've test driven a couple and know it won't be as manual as a real manual. I've been trying to think back to my days with the CL auto, decide exactly what frustrated me about it, and figure out how the IS would act in those situations. I wound up driving the CL is D4 most of the time, then hitting D5 once I was up to crusing speed on the freeway. I could do the same on the IS in sport mode.

I am not a fan of the Manu-matic.
The only thing you can do is control how far it upshifts. IE, if you dont want it to shift to 5th, you set it to 4. It will shift down on its own if you are accelerating hard. then shift back to fourth when you let off or hit red line. When you set it to 4, whe you hit redline you will bounce off the limiter.
Pretty much the exact opposite of what I would want. I want it to downshift when I want to, and upshift when I want it to. However, I wouldnt mind a safety that auto upshifts at redline.
In manual mode, The car shifts up and down as it pleases and will bounce off the limiter. WTH

Hate to burst your bubbles... but the Acura TL, CL, TLS, & CLS sportshift transmissions were such problem children that I have trouble with credibility as an example of a manumatic transmission.
I do notice that I need to anticipate my shifts maybe .25 seconds ahead of time, but I'm sorta used to it by now (in the GS's... the IS is the same way).

there may be a delay on upshifts if your pedal is floored but that is normal. I think it is better performance to have the computer upshift for you with it in "Power" mode then to shift with the paddles. The IS250 is fun to drive with the "revs" up. I like having the redline warning light too. The IS350 is a killer looking for victims if you get my drift....
