To start the ignition, depress the brake pedal and turn the key. To accelerate away from a standstill, depress the accelerator pedal like you would in an automated vehicle. In some tiptronic gearbox configurations, the transmission moves the first two speeds for you before allowing you to switch to manual mode.

What you should know about Tiptronic
One can easily discover frequent, acrimonious disputes about the advantages of manual versus automatic gears by browsing automotive journals and websites, and nowhere is this more evident than in the realm of sports vehicles. The 997 Turbo S and 991.1 GT3 are two examples of cars Porsche decided to only offer with the PDK transmission (launched with the 997.2 generation), therefore the 911 hasn’t been exempt from such arguments.
But since the transmission we’re talking about here was the first to give the Neunelfer a true automatic (as opposed to the Sportomatic, which was released in 1967 and was a manual transmission with the clutch controlled by a microswitch in the gear lever), that problem is more recent. Tiptronic made its debut in the 964, a car that already represented a generational shift for the 911.
The four-speed electro-hydraulically controlled Tiptronic gearbox, which was created in collaboration with ZF and Bosch and debuted in 1988, was dubbed “revolutionary” by Porsche at the time. It was a typical torque convertor transmission that seemed to provide the best of both worlds: when in “Drive,” it would automatically shift ratios as with any other automatic transmission, but by sliding the selector lever to one side, the driver could engage in manual shifting by pushing the lever forward to change up or backward to change down.
The mode or gear that was chosen was displayed on the speedometer. The variety of ratios was larger than was genuinely desirable because the Tiptronic ‘box only had four speeds, but Porsche somewhat compensated for this by giving it a “Intelligent Shift Programme.” One of five shift programmes that altered gear change points according to whether the driver wanted to cruise or get the most performance was selectable from an ECU that monitored inputs such vehicle and engine speed, throttle position, and longitudinal and lateral acceleration. Additionally, this electronic control has other advantages, such as preventing gear changes at inconvenient times, including when cornering, and preventing over-revving by automatically upshifting at maximum revs.
Porsche Tiptronic gearboxes are they trustworthy?
Why is the Porsche Cayenne lacking a PDK whereas the Macan has one? Why does Porsche still produce a Tiptronic when the PDK transmission is so much better?
As PCA’s technical director, I get asked these inquiries frequently. Understanding the differences between the two broadcasts will provide the solution. They both have automated transmissions, therefore there isn’t a clutch pedal. A Tiptronic is also widely renowned for its dependability and need for little maintenance, despite the fact that the PDK is quite sporty and quick to shift.
The Tiptronic has the strongest resemblance to a “typical” automatic transmission. Although it’s simple to write it off as a “slush-box,” Porsche has benefited greatly from it. Manually shifting through the gears is possible, but choosing a lower gear at the incorrect rpm won’t hurt the engine. The torque converter is what it has in common with other automatic transmissions, like the one in your dad’s Buick. The torque converter doubles the torque when transferring power from the engine to the transmission. Towing high loads effectively requires torque converters. The Macan has a lower tow rating than the Cayenne principally because of this. The Cayenne is rated for 7700lbs, however the Macan is only rated for less than 5,000lbs. This video provides a better explanation of the torque converter’s operation.
The Porsche Doppelkupplungsgetriebe (PDK) transmission functions somewhat like two gearboxes combined into one, with one clutch engaging even ratios and the other engaging odd gears. The software is so clever that it already has the next gear selected and ready for you to shift into. The shift mappings are modified in the Sport and Sport Plus modes, along with the suspension dampening and throttle response. Shifts happen more quickly, and if the automatic transmission is on, the engine revs up more before upshifts. Many drivers have realized that letting PDK handle the shifting is the quickest method to navigate curves.
Porsche initially used the renowned 956 Le Mans prototype race vehicle for PDK testing. The fact that PDK maintained the car on boost throughout upshifts was a significant improvement.
The two gearboxes that make up the PDK transmission are thoroughly explained visually in the video link below, explaining why it shifts so much more quickly than a Tiptronic.
Tiptronic is only available in the Cayenne lineup, which includes the incredibly sporty Cayenne Turbo GT, when looking for new Porsches. The Panamera is the only Porsche with an automatic transmission option other than PDK.
The Tiptronic originally made an appearance on the 964 in 1991, subsequently on the 968, according to the used car market. Mercedes-Benz provided the automatic transmission option for the 928. Along with the 986 and 987.1 Boxster models, the Tiptronic option was still available with the 993, 996, and 997.1 models. The Porsche PDK transmission made its début in 2009 in the 997.2 911 and 987.2 Boxster/Cayman, becoming the only automatic transmission available for the two-door sports car models. The Tiptronics have demonstrated to be extremely durable and dependable. Simply replacing the fluid as directed in your owner’s handbook constitutes maintenance. Although the PDK is just as dependable, track-day drivers should do more frequent fluid changes.
What does Porsche’s Tiptronic do?
The function that enables the driver to manually manage an automatic transmission is known by the brand name Tiptronic. The technology was created by the Porsche firm in 1990 and was first only installed on Porsche vehicles.
Porsche Tiptronic has two clutches, right?
Porsche unveiled their first automatic transmission way back in 1968. Porsche introduced the Sportomatic transmission in order to appeal to the market that didn’t want to manually change gears.
This transmission wasn’t an actual automatic. The driver was able to change gears by operating a vacuum-controlled clutch with a gear lever similar to one found in a manual transmission car. The absence of a clutch pedal was what made a difference, though. This transmission, which was utilized in Porsches up until 1980, represented an early attempt at a semi-automatic transmission.
The Tiptronic automatic, which was a ZF product, was the next. Porsche altered the ZF transmission to make it more responsive and athletic. Like modern automated vehicles, it also had a manual mode. The Tiptronic transmission was first employed in the 911 of the 964 generation in 1991, and it has since undergone modifications.
Porsche’s racing engineers had been working on a dual-clutch transmission known as the Porsche Doppelkupplungsgetriebe, or PDK, during this time. Porsche eventually installed the PDK transmission in production vehicles starting in 2005 after nearly 30 years of use and development in racing.
What is a Tiptronic 8-speed transmission?
The eight-speed tiptronic is a traditional torque-converter automatic transmission, and one of its greatest strengths is how smoothly and comfortably it shifts. Shifts in gear are smooth, impulsive, quick, and incredibly adaptable. It is a common feature in cars from Audi with longitudinally placed engines. The engine always runs close to its ideal operating point because of the eight gears’ minimal rpm jumps between them. Unwanted engine vibrations are balanced out by a rpm-adaptive torsion damper, allowing for economical driving at extremely low engine speeds.
The torque converter lockup clutch with integrated damper is another component that significantly contributes to the efficiency ensemble. The lockup torque converter connects the transmission and engine directly when driving normally. In some circumstances, it operates with limited slip, which when combined with the built-in damper allows for very low engine speeds without experiencing vibrations. Even though the “D” stage is still selected, an internal clutch separates the transmission from the engine when the car is stationary to prevent oil circulation losses in the converter. The clutch closes instantly once the driver lets off the brake, and the torque converter’s dampening effect assures a smooth drive-off.
Within the gear-shift unit, a compact steel box holds the dynamic shift program (DSP), which manages the eight-speed tiptronic. It makes use of a quick processor. In the “D” mode, DSP determines the ideal shift point on its own. It favors big gears and low engine speeds to facilitate an efficient driving style. The tiptronic’s second shift gate enables human control of the automatic transmission’s operation. This enables downshifting, for example, on winding descents to increase engine braking or to drive extremely sportily. By choosing later shift points, the automatic transmission improves driving characteristics when in sport mode. There is no mechanical connection between the selecting lever and the transmission; all communication is electrical (shift-by-wire).
The Audi start-stop system is compatible with the eight-speed tiptronic. For this, it incorporates a tiny, continuously filled hydraulic reservoir. Its oil capacity, which is around 100 milliliters (0.1 US qt) when beginning after a stop, is pressured by a spring-loaded piston, which is required for drive-off. Within a very short amount of time, the transmission is prepared to begin.
The eight-speed tiptronic includes an electronic oil pump in select Audi models. It takes care of the transmission’s lubrication and makes it possible to engage the gear required for an engine restart following a coasting period. This makes it feasible for the car to turn off its engine while driving when it is not required for propulsion because of mild hybrid technology. A clutch is open near the wheel sets when the car is coasting and the engine is running at idle. The gearbox control device ensures highly comfortable driving starts and recognizes stop-and-go conditions.
Can a transmission be ruined by Tiptronic?
Nothing will be harmed or weakened by it. It is completely acceptable to use such mode IF the car has a shift gate built into the transmission that allows the stick to be bumped up for an upshift and down for a downshift.
What is the mechanism of Porsche Sportomatic?
Sportomatic was essentially a manual transmission with a vacuum-operated single-disc dry clutch. It was a modified four-speed 911 gearbox. The flywheel was replaced by a torque converter, which was designed to smooth the electro-mechanical shifts in the transmission and enable the vehicle to remain stationary while the clutch was engaged.
Can a Porsche be over revved?
In ranges 4, 5, and 6, automobiles with 0% overrevs typically work nicely. Typically, hitting the rpm limits results in Range 1 over revs. Ranges two and above are mechanical over revs but remain within the engine’s internal safety limits. Ranges 4-6 are major and could one day be devastating. A Range 4 or higher vehicle will not be CPO’d by Porsche.
Remember that each rev lasts 0.00833 seconds at the rev limiter (7200 RPM), so that your 13,991 Range 1 revs at the limiter took 116 seconds to complete, 63 Range 2 revs took 0.5 seconds, and 21 Range 3 revs took 0.2 seconds.
What is a mistake to avoid when using an automatic transmission?
You probably believe it’s preferable to keep your car in neutral if you don’t think you’ll be driving for a time, as when you’re stopped at a red light or in traffic.
Also a horrible idea is this. Leaving your automobile in neutral in these circumstances is better for your car even if it could waste gas.
Leaving your automobile in neutral might be dangerous as well. What kind of traffic starts accelerating, for instance. Leaving your car in neutral reduces its movement and speed.
Tiptronic can it be changed while driving?
A query regarding using a modern automatic transmission with the manual option came from a reader. His query is as follows:
“Top Gear PH, hello! In an automatic vehicle, is it acceptable to switch from drive to manual (+/-) while I’m cruising? I’m hoping you can respond to my query. So excited! I’m grateful.”
There is nothing to worry about and you can. This is what these contemporary automatic transmissions with a manual mode are designed to do. It was designed to go from automated to manual mode, even while traveling at a high speed.
A few improvements to the automatic transmission have been made in the last ten years or so. Modern automatic transmissions now have a manual mode that allows the driver to manually shift gears, a feature that was first offered in exotic automobiles. However, unlike a true manual transmission, which uses a pedal to drive a hydraulic or cable-controlled clutch, modern manual transmissions just have switches or a shifter that needs to be tugged or pushed to change speeds.
With these gearboxes, the driver is free to choose a certain gear whenever they want. The ability to select one gear and maintain it gives the driver additional control in manual mode. The more control you have as a driver, the better.
