tiptronic any good??

[dporsche74]

hello guys,

I am about to look at a 91 911 tiptronic trans, I was wondering how does it the tip work , is it any good are they still a slush boxes, , This will be my first auto and liitle nervous, does it work well any known problems, , any inout will be great
Also if it has the tip is it still prone to the dual mass flywheel problems

thanks

the tiptronic transmission is nothing more than a regular, old school slushbox (i.e. torque converter) automatic transmission.

I do not believe it uses a dual mass flywheel. From my understanding of what the dual mass flywheel was for, it wouldn't make any sense in an automatic, which does not have a clutch. The torque converter would seem to take up any vibration issues, making a dual mass flywheel unnecessary.

The tiptronic is pretty standard autotrans stuff, I don't think it has any known problems.

The first Porsche I drove was a very early yellow targa tiptronic. It was a blast to drive. It sounded great, cornered exellent and freed up my right hand for contact sports

The sound and handling will be the same as a manual car. As stated above, "Tiptronic" is just Porsche's marketing name for an automatic transmission.

I find them boring.

better than a Spurtomatic... or not?

Porsche's new PDK is a whole different animal.

Isn't that what was being said about tiptronic when it came out and I seem to recall sportomatic getting good press as well

Sort of.

To me, if it has a torque converter, it's a plain automatic. I can't stand the lag between the shift command and the tranny actually engaging the next gear.

A torque converter also saps throttle response.

The new PDK has no torque converter, so we'll see......

(mine will still have a clutch pedal)

Generally, I am sure the tip's are fine drivers. You might notice they are also very inexpensive as compared to a manual trans, same year/condition. WHY? Probably because most P owners want to shift gears.
If you want one for daily driving in stop and go traffic and want to hang onto it for a while, presuming everything else checks out, its your choice and money. Resale will be a bear. Whatever you do, make sure you know about each year's foibles. Is this 964 a C4? I'd avoid it if it is, manual or tip.

looking at 3 964 , all the same price range, two are c2 tips and one is c4 manual ,
do noticed the tip are usally 40% less then manuals

Go drive it and tell us what you think.

IMO, you should match the tranny to the power curve of the motor. High revving motors with no guts down low makes for a poor auto tranny experience. For this reason, I prefer manuals in Porsches.

In Corvettes or other high torque at low rpm V8 vehicles, I prefer an auto.

If you plan to track it- manual no doubt.

Well, maybe... but that was because those were the best offerings of the time.

An excerpt from my PDK review on Autoblog:

"Technically speaking, the new PDK is a conventional 7-speed manual gearbox with two electronically-controlled clutch packs. One multi-plate clutch pack controls the odd gears (and reverse), and the other controls the even gears. As one clutch pack is engaged, the other disengages the previous gear and readies itself for the next shift (up or down). Gear selection is done manually via twin sliding levers on the steering wheel (push forward to upshift, pull back to downshift) or with the console-mounted shift lever. It can also be completely automatic as engine electronics shift gears based on engine speed, engine load and vehicle speed. The PDK in standard mode shifts smoother than the outgoing Tiptronic. However, when the console-mounted "Sport" button is depressed, the shifts are accelerated to outpace in speed and feel those of the even sportier Tiptronic S. In "Sport Plus" mode, shifts are blindingly fast – they include a swift kick in the back with each upshift (Porsche engineers realize that hundredths of a second count on the track or in an autocross, so they didn't want to leave anything on the table).

Introduced nearly 20 years ago, Tiptronic was at best an electronically controlled transmission with a torque-converter. At worst, it was a slow-shifting slushbox vehemently shunned by enthusiasts. In a complete reversal of trend, Porsche expects enthusiasts to prefer PDK over a traditional 6-speed manual transmission. Shake your head in disbelief, and then read on... First, the lightning-fast shifts with PDK best even the quickest manual or Tiptronic gear change (e.g., a 6th to 2nd shift took 1.05 sec with Tiptronic S – PDK drops it to just .42 sec). Second, there is no tractive-force interruption with PDK (no measurable loss of power to the pavement). Third, overall acceleration is quicker with PDK (Carrera S Coupe launches 0-60 mph in 4.5 sec with a manual, just 4.1 sec with PDK). Finally, PDK is absolutely consistent lap after lap. Few drivers, if any, can match that.

The new dual-clutch PDK leaves manual transmission junkies in the Dark Ages, and more than a bit miffed about the future of their century-old gearbox. Soccer moms will want the PDK for its smooth and seamless shifting, improved fuel economy, and reduced engine noise. Enthusiasts will choose the PDK for its shift speed, consistency, and lack of power loss to the wheels. Only passionate "traditionalists" who insist on three-pedal shifting for the sheer visceral enjoyment will choose the slower, less efficient, and more cumbersome 6-speed manual. Like the cranks on car windows being replaced by electric lifts, Porsche's dual-clutch spells doom for the manual transmission – regrettably PDK proves its days are ultimately numbered."

torque converter = slush box

these things are like putting CIS on a sports car
